Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation General Motors Company (sometimes referred to in this Quarterly Report on Form 10-Q as we, our, us, ourselves, the Company, General Motors or GM) designs, builds and sells trucks, crossovers, cars and automobile parts worldwide and is investing in and growing an autonomous vehicle business. We also provide automotive financing services through General Motors Financial Company, Inc. (GM Financial). We analyze the results of our operations through the following operating segments: GM North America (GMNA), GM International Operations (GMIO), GM South America (GMSA), Cruise, and GM Financial. Our GMSA and GMIO operating segments are reported as one, combined international segment, GM International (GMI). Cruise is our global segment responsible for the development and commercialization of autonomous vehicle technology. Nonsegment operations are classified as Corporate. Corporate includes certain centrally recorded income and costs such as interest, income taxes, corporate expenditures and certain nonsegment-specific revenues and expenses. The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements include all adjustments, which consist of normal recurring adjustments and transactions or events discretely impacting the interim periods, considered necessary by management to fairly state our results of operations, financial position and cash flows. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2019 Form 10-K. Except for per share amounts or as otherwise specified, dollar amounts presented within tables are stated in millions. Principles of Consolidation We consolidate entities that we control due to ownership of a majority voting interest and we consolidate variable interest entities (VIEs) when we are the primary beneficiary. Our share of earnings or losses of nonconsolidated affiliates is included in our consolidated operating results using the equity method of accounting when we are able to exercise significant influence over the operating and financial decisions of the affiliate. Recently Adopted Accounting Standards Effective January 1, 2020, we adopted Accounting Standards Update (ASU) 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" (ASU 2016-13), which requires entities to use a new impairment model based on current expected credit losses (CECL) rather than incurred losses. Estimated credit losses under CECL consider relevant information about past events, current conditions and reasonable and supportable forecasts that affect the collectability of financial assets, resulting in recognition of lifetime expected credit losses at initial recognition of the related asset. We adopted ASU 2016-13 on a modified retrospective basis by recognizing an after-tax cumulative-effect adjustment to the opening balance of Retained earnings of $660 million, inclusive of $643 million related to GM Financial. The application of ASU 2016-13 increased our allowance for loan losses related to GM Financial receivables, net by $801 million and had an insignificant impact to our allowance for credit losses for Accounts and notes receivable and no adoption impact to Marketable debt securities on our condensed consolidated balance sheets. In March 2020, the Financial Accounting Standards Board issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), which provides optional expedients and exceptions for applying U.S. GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. We do not believe the discontinuance of LIBOR will be a significant event for our Automotive arrangements. A substantial portion of GM Financial’s indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. Effective July 1, 2020, we adopted ASU 2020-04 on a prospective basis. The adoption of, and future elections under, ASU 2020-04 are not expected to have a material impact on our condensed consolidated financial statements as the standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on GM Financial's contracts, hedging relationships and other transactions.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies The information presented on Marketable Debt Securities, Accounts and Notes Receivable and GM Financial Receivables supplements the Significant Accounting Policies information presented in our 2019 Form 10-K to reflect the adoption of ASU 2016-13 that became effective January 1, 2020. See our 2019 Form 10-K for a description of our significant accounting policies in effect prior to the adoption of ASU 2016-13. Marketable Debt Securities We classify marketable debt securities as either available-for-sale or trading. Various factors, including turnover of holdings and investment guidelines, are considered in determining the classification of securities. Available-for-sale debt securities are recorded at fair value with unrealized gains, and losses that are not credit related, recorded net of applicable taxes in Accumulated other comprehensive loss until realized. Credit losses are recorded in Interest income and other non-operating income, net. An evaluation is made quarterly to determine if any portion of unrealized losses on available-for-sale debt securities is related to credit losses or whether any unrealized losses recorded in Accumulated other comprehensive loss need to be reclassified. Non-credit related unrealized losses are reclassified to Interest income and other non-operating income, net if we intend to sell the security or it is more likely than not that we will be required to sell the security before the recovery of the unrealized loss. Accounts and Notes Receivable Accounts and notes receivable primarily consists of amounts that are due and payable from our customers for the sale of vehicles, parts, and accessories. We evaluate the collectability of receivables each reporting period and record an allowance for doubtful accounts to present the net amount expected to be collected on our receivables. Additions to the allowance are charged to bad debt expense and reported in Automotive and other selling, general and administrative expense. GM Financial Receivables Finance receivables are carried at amortized cost, net of allowance for loan losses. Provisions for loan losses are charged to operations in amounts sufficient to maintain the allowance for loan losses at levels considered adequate to cover expected credit losses on the finance receivables. For retail finance receivables, GM Financial uses static pool modeling techniques to determine the allowance for loan losses expected over the remaining life of the receivables, which is supplemented by management judgment. The modeling techniques incorporate reasonable and supportable forecasts of economic conditions over the expected remaining life of the finance receivables. The economic forecasts incorporate factors which vary by region that GM Financial believes will have the largest impact on expected losses, including unemployment rates, interest rate spreads, disposable personal income and growth rates in gross domestic product. Troubled debt restructurings (TDRs) are grouped separately for purposes of measuring the allowance. The allowance for TDRs uses static pool modeling techniques like non-TDR retail finance receivables to determine the expected loss amount. The expected cash flows of the receivables are then discounted at the original weighted average effective interest rate of the pool. Factors considered when estimating the allowance for TDRs are based on an evaluation of historical and current information, which may be supplemented by management judgment. Finance charge income from loans classified as TDRs is accounted for in the same manner as other accruing loans. Cash collections on these loans are allocated according to the same payment hierarchy methodology applied to loans that are not classified as TDRs. Commercial finance receivables are carried at amortized cost, net of allowance for loan losses and any amounts held under a cash management program. GM Financial establishes the allowance for loan losses based on historical loss experience, as well as the forecast for industry vehicle sales, which is the economic indicator believed to have the largest impact on expected losses.

In the nine months ended September 30, 2020, the provision for loan losses increased primarily due to increased expected charge-offs and decreased expected recoveries as a result of the economic impact of the novel strain of the coronavirus (COVID-19) pandemic.

GM Financial reviews the ongoing credit quality of retail finance receivables based on customer payment activity. A retail account is considered delinquent if a substantial portion of a scheduled payment has not been received by the date the payment was contractually due. Retail finance receivables are collateralized by vehicle titles and, subject to local laws, GM Financial generally has the right to repossess the vehicle in the event the customer defaults on the payment terms of the contract. The accrual of finance charge income had been suspended on delinquent retail finance receivables with contractual amounts due of $742 million and $875 million at September 30, 2020 and December 31, 2019. The following table is a consolidated summary of the delinquency status of the outstanding amortized cost of retail finance receivables for each vintage of the portfolio at September 30, 2020:

(a)Represents the contractual amounts of delinquent retail finance receivables, which is not significantly different than the outstanding amortized cost for such receivables.

The outstanding amortized cost of retail finance receivables that are considered TDRs was $2.3 billion at September 30, 2020, including $317 million in nonaccrual loans.

Commercial Finance Receivables GM Financial's commercial finance receivables consist of dealer financings, primarily for inventory purchases. Proprietary models are used to assign a risk rating to each dealer. GM Financial performs periodic credit reviews of each dealership and adjusts the dealership's risk rating, if necessary. The commercial finance receivables on nonaccrual status were insignificant at September 30, 2020.

Prior to January 1, 2020, GM Financial estimated the allowance for loan losses based on an analysis of the experience of comparable commercial lenders. Effective January 1, 2020, GM Financial establishes the allowance for loan losses based on historical loss experience for the consolidated portfolio, in addition to forecast for industry vehicle sales. The updated risk rating categories are as follows:


Rating						Description
I						Performing accounts with strong to acceptable financial metrics with at least satisfactory capacity to meet financial commitments.
II						Performing accounts experiencing potential weakness in financial metrics and repayment prospects resulting in increased monitoring.
III						Non-Performing accounts with inadequate paying capacity for current obligations and have the distinct possibility of creating a loss if deficiencies are not corrected.
IV						Non-Performing accounts with inadequate paying capacity for current obligations and inherent weaknesses that make collection of liquidation in full highly questionable or improbable.

Dealers with III and IV risk ratings are subject to additional monitoring and restrictions on funding, including suspension of lines of credit and liquidation of assets. The following table summarizes the credit risk profile by dealer risk rating of commercial finance receivables at September 30, 2020:


	Year of Origination(a)																September 30, 2020

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill We had Goodwill of $1.9 billion at September 30, 2020, which includes $1.3 billion related to GM Financial's North America reporting unit. Since December 31, 2019, the COVID-19 pandemic has caused material disruption to businesses, resulting in an economic slowdown. The economic and social uncertainty resulting from the COVID-19 pandemic indicated that it was more likely than not that a goodwill impairment existed at March 31, 2020 for GM Financial's North America reporting unit. Therefore, in the three months ended March 31, 2020, we performed an event-driven goodwill impairment test for GM Financial's North America reporting unit and determined no goodwill impairment existed. The fair value of GM Financial's North America reporting unit at March 31, 2020 was determined based on valuation techniques using the best available information, primarily discounted cash flow projections. We make significant assumptions and estimates about the extent and timing of future cash flows. There can be no assurance that anticipated financial results will be achieved. Under multiple scenarios, including fully weighting the downside cash flow scenario, the estimated fair value of GM Financial's North America reporting unit at March 31, 2020 exceeded its carrying amount. Since March 31, 2020, we noted no further material deterioration in our economic performance or outlook that would indicate further testing of goodwill impairment was warranted. Future goodwill impairment could be recognized should economic uncertainty continue, thereby resulting in a prolonged economic slowdown and a corresponding decline in the fair value of our reporting units.

Variable Interest Entities [Abstract]

Variable Interest Entities

GM Financial uses special purpose entities (SPEs) that are considered VIEs to issue variable funding notes to third party, bank-sponsored warehouse facilities or asset-backed securities to investors in securitization transactions. The debt issued by these VIEs is backed by finance receivables and leasing-related assets transferred to the VIEs (Securitized Assets). GM Financial determined that it is the primary beneficiary of the SPEs because the servicing responsibilities for the Securitized Assets give GM Financial the power to direct the activities that most significantly impact the performance of the VIEs and the variable interests in the VIEs give GM Financial the obligation to absorb losses and the right to receive residual returns that could potentially be significant. The assets of the VIEs serve as the sole source of repayment for the debt issued by these entities. Investors in the notes issued by the VIEs do not have recourse to GM Financial or its other assets, with the exception of customary representation and warranty repurchase provisions and indemnities that GM Financial provides as the servicer. GM Financial is not required to provide additional financial support to these SPEs. While these subsidiaries are included in GM Financial's condensed consolidated financial statements, they are separate legal entities and their assets are legally owned by them and are not available to GM Financial's creditors.

The following table summarizes the assets and liabilities related to GM Financial's consolidated VIEs:


	September 30, 2020		December 31, 2019
Restricted cash – current	$	2,316	$	2,202
Restricted cash – non-current	$	409	$	441

GM Financial recognizes finance charge, leased vehicle and fee income on the Securitized Assets and interest expense on the secured debt issued in a securitization transaction and records a provision for loan losses to recognize probable loan losses inherent in the finance receivables.

(b)Excludes our 364-day, $2.0 billion facility designated for exclusive use by GM Financial.

(c)Includes coupon rates on debt denominated in various foreign currencies and interest free loans.

Unsecured debt primarily consists of revolving credit facilities and senior notes. In March 2020, we borrowed: (1) $3.4 billion against our three-year, $4.0 billion facility; (2) $2.0 billion against our three-year, $3.0 billion facility, which reduced to $2.0 billion in May 2020 (three-year, $2.0 billion transformation facility); and (3) $10.5 billion against our five-year, $10.5 billion facility, with maturity dates ranging from 2021 to 2023. In September 2020, we repaid $3.2 billion of the three-year, $4.0 billion facility and repaid in full the three-year, $2.0 billion transformation facility. In October 2020, we repaid $3.9 billion of our five-year, $10.5 billion facility.

In April 2020, we renewed our 364-day, $2.0 billion facility designated for exclusive use by GM Financial for an additional 364-day term and extended $3.6 billion of the three-year, $4.0 billion facility for an additional year expiring in April 2022. The remaining portion will expire in April 2021, unless extended. As part of the extension of the three-year, $4.0 billion facility, we have agreed not to execute any share repurchases until we no longer have outstanding borrowings under the revolving credit facilities, except for the three-year, $2.0 billion transformation facility. In addition, we are restricted from paying dividends on our common shares if outstanding borrowings under the revolving credit facilities exceed $5.0 billion, with the exception of the three-year, $2.0 billion transformation facility.

In May 2020, we issued $4.0 billion in aggregate principal amount of senior unsecured notes with a weighted average interest rate of 6.11% and maturity dates ranging from 2023 to 2027. The notes are governed by a sixth supplemental indenture and the same base indenture that governs our existing notes, which contains terms and covenants customary for these types of securities, including a limitation on the amount of certain secured debt we may incur. The net proceeds from the issuance of these senior unsecured notes provide additional financial flexibility and will be used for general corporate purposes. In May 2020, we also entered into a new unsecured 364-day, $2.0 billion revolving credit facility as an additional source of available liquidity. In August 2020, we repaid $500 million of our floating rate senior unsecured debt upon maturity.

Secured debt consists of revolving credit facilities and securitization notes payable. Most of the secured debt was issued by VIEs and is repayable only from proceeds related to the underlying pledged assets. Refer to Note 10 for additional information on GM Financial's involvement with VIEs. GM Financial is required to hold certain funds in restricted cash accounts to provide additional collateral for borrowings under certain secured credit facilities. The weighted-average interest rate on secured debt was 2.22% at September 30, 2020. The revolving credit facilities have maturity dates ranging from 2020 to 2026 and securitization notes payable have maturity dates ranging from 2021 to 2028. At the end of the revolving period, if not renewed, the debt of revolving credit facilities will amortize over a defined period. In the nine months ended September 30, 2020, GM Financial renewed revolving credit facilities with total borrowing capacity of $17.3 billion and issued $16.6 billion in aggregate principal amount of securitization notes payable with an initial weighted average interest rate of 1.33% and maturity dates ranging from 2021 to 2028.

Unsecured debt consists of senior notes, credit facilities and other unsecured debt.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Litigation-Related Liability and Tax Administrative Matters In the normal course of our business, we are named from time to time as a defendant in various legal actions, including arbitrations, class actions and other litigation. We identify below the material individual proceedings and investigations where we believe a material loss is reasonably possible or probable. We accrue for matters when we believe that losses are probable and can be reasonably estimated. At September 30, 2020 and December 31, 2019, we had accruals of $1.2 billion and $1.3 billion in Accrued liabilities and Other liabilities. In many matters, it is inherently difficult to determine whether loss is probable or reasonably possible or to estimate the size or range of the possible loss. Accordingly, adverse outcomes from such proceedings could exceed the amounts accrued by an amount that could be material to our results of operations or cash flows in any particular reporting period.

Proceedings Related to Ignition Switch Recall and Other Recalls In 2014 we announced various recalls relating to safety and other matters. Those recalls included recalls to repair ignition switches that could, under certain circumstances, unintentionally move from the “run” position to the “accessory” or “off” position with a corresponding loss of power, which could in turn prevent airbags from deploying in the event of a crash.

Appellate Litigation Regarding Successor Liability Ignition Switch Claims In 2016, the U.S. Court of Appeals for the Second Circuit held that the 2009 order of the United States Bankruptcy Court for the Southern District of New York (Bankruptcy Court) approving the sale of substantially all of the assets of Motors Liquidation Company (MLC), formerly known as General Motors Corporation, to GM free and clear of, among other things, claims asserting successor liability for obligations owed by

MLC could not be enforced to bar claims against GM asserted by either plaintiffs who purchased used vehicles after the sale or against purchasers who asserted claims relating to the ignition switch defect, including pre-sale personal injury claims and economic-loss claims.

Economic-Loss Claims We are aware of over 100 putative class actions that were filed against GM in U.S. and Canadian courts alleging that consumers who purchased or leased vehicles manufactured by GM or MLC had been economically harmed by one or more of the 2014 recalls and/or the underlying vehicle conditions associated with those recalls (economic-loss cases). In general, these economic-loss cases seek recovery for purported compensatory damages, such as alleged benefit-of-the-bargain damages or damages related to alleged diminution in value of the vehicles, as well as punitive damages, injunctive relief and other relief.

Many of the pending U.S. economic-loss claims have been transferred to, and consolidated in, a single federal court, the U.S. District Court for the Southern District of New York (Southern District). These plaintiffs have asserted economic-loss claims under federal and state laws, including claims relating to recalled vehicles manufactured by GM and claims asserting successor liability relating to certain recalled vehicles manufactured by MLC.

In August 2017, the Southern District granted our motion to dismiss the successor liability claims of plaintiffs in seven of the sixteen states at issue on the motion and called for additional briefing to decide whether plaintiffs' claims can proceed in the other nine states. In December 2017, the Southern District granted GM's motion and dismissed the plaintiffs' successor liability claims in an additional state, but found that there are genuine issues of material fact that prevent summary judgment for GM in eight other states. In January 2018, GM moved for reconsideration of certain portions of the Southern District's December 2017 summary judgment ruling. That motion was granted in April 2018, dismissing plaintiffs' successor liability claims in any state where New York law applies.

In September 2018, the Southern District granted our motion to dismiss claims for lost personal time (in 41 out of 47 jurisdictions) and certain unjust enrichment claims, but denied our motion to dismiss plaintiffs’ economic loss claims in 27 jurisdictions under the "manifest defect" rule.

In August 2019, the Southern District granted our motion for summary judgment on plaintiffs’ economic loss “benefit of the bargain” damage claims (the August 2019 Opinion). The Southern District held that plaintiffs’ conjoint analysis-based damages model failed to establish that plaintiffs suffered difference-in-value damages and without such evidence, plaintiffs’ difference-in-value damage claims fail under the laws of all three bellwether states: California, Missouri and Texas. Later in August 2019, the bellwether plaintiffs filed a motion requesting that the Southern District reconsider its summary judgment decision or allow an interlocutory appeal if reconsideration is denied. In December 2019, the Southern District denied plaintiffs' motion for reconsideration of the August 2019 Opinion, but granted the plaintiffs' motion for certification of an interlocutory appeal. On April 1, 2020, the Second Circuit Court of Appeals (the Second Circuit) granted the bellwether plaintiffs' petition seeking leave to appeal the August 2019 Opinion. On April 15, 2020, the bellwether plaintiffs and GM filed a Stipulation to withdraw the appeal from the Second Circuit based on the class settlement agreement described below. Pursuant to the Stipulation, the bellwether plaintiffs can reinstate the appeal no later than April 2021. The Second Circuit endorsed the Stipulation by order on April 16, 2020.

In September 2019, GM filed an updated motion for summary judgment on plaintiffs’ remaining economic loss claims that were not addressed in the Southern District’s August 2019 Opinion and renewed its evidentiary motion seeking to strike the opinions of plaintiff’s expert on plaintiffs’ alleged “lost time” damages associated with having the recall repairs performed.

In March 2020, GM, plaintiffs and the MLC GUC Trust (GUC Trust) reached a settlement agreement (Class Settlement Agreement) to resolve on a national basis the economic loss claims of the proposed settlement class and proposed sub-classes, consisting of consumers who purchased or leased GM vehicles covered by the seven 2014 safety recalls at issue in the Southern District and the Bankruptcy Court. The proposed Class Settlement Agreement provides a common fund of approximately $120 million for settlement class members, of which GM will fund approximately $70 million and the GUC Trust will fund the remaining $50 million. GM will also pay attorneys’ fees and costs that may be awarded by the Southern District to plaintiffs’ counsel up to a maximum of $35 million. In April 2020, the Avoidance Action Trust (AAT), GM and plaintiffs reached a tentative settlement under which the AAT will pay an insignificant amount and will be added as a settling party to the Class Settlement Agreement. During April and May 2020, the Southern District entered orders granting preliminary approval of the Class Settlement Agreement. The deadline for class members to object to or opt-out of the Class Settlement Agreement was October 2020. The final fairness hearing is set for December 2020.

Contingently Issuable Shares Under the Amended and Restated Master Sale and Purchase Agreement between GM and MLC, GM was obligated to issue additional shares (Adjustment Shares) of our common stock if allowed general unsecured claims against the GUC Trust, as estimated by the Bankruptcy Court, exceed $35.0 billion. In March 2020, in conjunction with the Class Settlement Agreement, the GUC Trust filed a motion in the Bankruptcy Court seeking approval to enter into and take actions necessary to execute the Class Settlement Agreement, and seeking Bankruptcy Court authorization permitting the GUC Trust to distribute $300 million of GUC Trust assets to its unitholders and entry into a mutual release agreement with GM that would release GM from any and all claims, including any that would require GM to issue any Adjustment Shares. Bankruptcy Court approval of the GUC Trust motion is a condition precedent to preliminary approval of the Class Settlement Agreement by the Southern District. In April 2020, the Bankruptcy Court entered an order approving the GUC Trust's motion in its entirety. In May 2020, the approval and the mutual release agreement became binding and enforceable and GM was fully released from its potential Adjustment Shares obligation.

Personal Injury Claims We also are aware of several hundred actions pending in various courts in the U.S. and Canada alleging injury or death as a result of defects that may be the subject of the 2014 recalls (personal injury cases). In general, these cases seek recovery for purported compensatory damages, punitive damages and/or other relief. Since 2016, several bellwether trials of personal injury cases have taken place in the Southern District and in a Texas state court, which is administering a Texas state multi-district litigation. None of these trials resulted in a finding of liability against GM.

Government Matters In connection with the 2014 recalls, we have from time to time received subpoenas and other requests for information related to investigations by agencies or other representatives of U.S. federal, state and the Canadian governments. GM is cooperating with all reasonable pending requests for information. Any existing governmental matters or investigations could in the future result in the imposition of damages, fines, civil consent orders, civil and criminal penalties or other remedies.

The total amount accrued for the 2014 recalls at September 30, 2020 reflects amounts for a combination of settled but unpaid matters, and for the remaining unsettled investigations, claims and/or lawsuits relating to the ignition switch recalls and other related recalls to the extent that such matters are probable and can be reasonably estimated. The amounts accrued for those unsettled investigations, claims, and/or lawsuits represent a combination of our best single point estimates where determinable and, where no such single point estimate is determinable, our estimate of the low end of the range of probable loss with regard to such matters, if that is determinable. We will continue to consider resolution of pending matters involving ignition switch recalls and other recalls where it makes sense to do so.

GM Korea Wage Litigation GM Korea is party to litigation with current and former hourly employees in the appellate court and Incheon District Court in Incheon, Korea. The group actions, which in the aggregate involve more than 10,000 employees, allege that GM Korea failed to include bonuses and certain allowances in its calculation of Ordinary Wages due under Korean regulations. In 2012, the Seoul High Court (an intermediate-level appellate court) affirmed a decision in one of these group actions involving five GM Korea employees which was contrary to GM Korea's position. GM Korea appealed to the Supreme Court of the Republic of Korea (Korean Supreme Court). In 2014, the Korean Supreme Court largely agreed with GM Korea’s legal arguments and remanded the case to the Seoul High Court for consideration consistent with earlier Korean Supreme Court precedent holding that while fixed bonuses should be included in the calculation of Ordinary Wages, claims for retroactive application of this rule would be barred under certain circumstances. In 2015, on reconsideration, the Seoul High Court held in GM Korea’s favor, after which the plaintiffs appealed to the Korean Supreme Court. In July 2020, the Korean Supreme Court held in GM Korea's favor. In light of this decision, we believe the probability that we will incur a material loss is remote and we estimate our loss in excess of amounts accrued is insignificant at September 30, 2020.

GM Korea is also party to litigation with current and former salaried employees over allegations relating to Ordinary Wages regulation and whether to include fixed bonuses in the calculation of Ordinary Wages. In 2017, the Seoul High Court held that certain workers are not barred from filing retroactive wage claims. GM Korea appealed this ruling to the Korean Supreme Court. The Korean Supreme Court has not yet rendered a decision. We estimate our reasonably possible loss in excess of amounts accrued to be approximately $170 million at September 30, 2020. Both the scope of claims asserted and GM Korea's assessment of any or all of the individual claim elements may change if new information becomes available or the legal or regulatory frameworks change.

GM Korea is also party to litigation with current and former subcontract workers over allegations that they are entitled to the same wages and benefits provided to full-time employees, and to be hired as full-time employees. In May 2018 and September 2020, the Korean labor authorities issued adverse administrative orders finding that GM Korea must hire certain current subcontract workers as full-time employees. GM Korea appealed the May 2018 order and plans to appeal the September 2020

order. In June 2020, the Seoul High Court ruled against GM Korea in one of the subcontract workers claims. GM Korea has appealed this decision to the Korean Supreme Court. At September 30, 2020, our accrual covering certain asserted claims and claims that we believe are probable of assertion and for which liability is probable was approximately $210 million. We estimate the reasonably possible loss in excess of amounts accrued for other current subcontract workers who may assert similar claims to be approximately $110 million at September 30, 2020. We are currently unable to estimate any possible loss or range of loss that may result from additional claims that may be asserted by former subcontract workers.

GM Brazil Indirect Tax Claim In 2019, the Superior Court of Brazil rendered favorable decisions on three cases brought by GM Brazil challenging whether a certain state value-added tax should be included in the calculation of federal gross receipts taxes. Those decisions granted the Company the right to recover, through offset of federal tax liabilities, certain amounts collected by the government between August 2001 and February 2017. As a result, GM Brazil recorded pre-tax recoveries of $123 million in the three months ended September 30, 2019 and $1.4 billion in pre-tax recoveries in the nine months ended September 30, 2019 and the year ended December 31, 2019, in Automotive and other cost of sales. Realization of these recoveries depends on the timing of administrative approvals and generation of federal tax liabilities eligible for offset. The Brazilian IRS has filed a Motion of Clarification on this matter with the Brazilian Supreme Court, which motion is awaiting decision. In addition, we expect third parties to make claims on some or all of the pre-tax recoveries, against which GM intends to defend.

Other Litigation-Related Liability and Tax Administrative Matters Various other legal actions, including class actions, governmental investigations, claims and proceedings are pending against us or our related companies or joint ventures, including matters arising out of alleged product defects; employment-related matters; product and workplace safety, vehicle emissions and fuel economy regulations; product warranties; financial services; dealer, supplier and other contractual relationships; government regulations relating to competition issues; tax-related matters not subject to the provision of Accounting Standards Codification 740, Income Taxes (indirect tax-related matters); product design, manufacture and performance; consumer protection laws; and environmental protection laws, including laws regulating air emissions, water discharges, waste management and environmental remediation from stationary sources.

There are several putative class actions pending against GM in federal courts in the U.S., in the Provincial Courts in Canada and in Israel alleging that various vehicles sold, including model year 2011-2016 Duramax Diesel Chevrolet Silverado and GMC Sierra vehicles, violate federal, state and foreign emission standards. We are unable to estimate any reasonably possible loss or range of loss that may result from these actions. GM has also faced a series of additional lawsuits in the U.S. based on these allegations, including putative shareholder class actions claiming violations of federal securities law and a shareholder demand lawsuit. The securities lawsuits have been voluntarily dismissed by the plaintiffs in those actions.

We believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated. It is possible that the resolution of one or more of these matters could exceed the amounts accrued in an amount that could be material to our results of operations. We also from time to time receive subpoenas and other inquiries or requests for information from agencies or other representatives of U.S. federal, state and foreign governments on a variety of issues.

Indirect tax-related matters are being litigated globally pertaining to value added taxes, customs, duties, sales, property taxes and other non-income tax related tax exposures. The various non-U.S. labor-related matters include claims from current and former employees related to alleged unpaid wage, benefit, severance and other compensation matters. Certain administrative proceedings are indirect tax-related and may require that we deposit funds in escrow or provide an alternative form of security. Some of the matters may involve compensatory, punitive or other treble damage claims, environmental remediation programs or sanctions that, if granted, could require us to pay damages or make other expenditures in amounts that could not be reasonably estimated at September 30, 2020. We believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated. For indirect tax-related matters we estimate our reasonably possible loss in excess of amounts accrued to be up to approximately $750 million at September 30, 2020.

Takata Matters In May 2016, the National Highway Traffic Safety Administration (NHTSA) issued an amended consent order requiring Takata to file defect information reports (DIRs) for previously unrecalled front airbag inflators that contain phased-stabilized ammonium nitrate-based propellant without a moisture absorbing desiccant on a multi-year, risk-based schedule through 2019 impacting tens of millions of vehicles produced by numerous automotive manufacturers. NHTSA concluded that the likely root cause of the rupturing of the airbag inflators is a function of time, temperature cycling and environmental moisture.

Although we do not believe there is a safety defect at this time in any unrecalled GM vehicles within scope of the Takata DIRs, in cooperation with NHTSA we have filed Preliminary DIRs covering certain of our GMT900 vehicles, which are full-size pickup trucks and sport utility vehicles (SUVs). We have also filed petitions for inconsequentiality with respect to the vehicles subject to those Preliminary DIRs. NHTSA has consolidated our petitions and will rule on them at the same time.

While these petitions have been pending, we have provided NHTSA with the results of our long-term studies and the studies performed by third-party experts, all of which form the basis for our determination that the inflators in these vehicles do not present an unreasonable risk to safety and that no repair should ultimately be required.

Accordingly, no warranty provision has been made for any repair associated with our vehicles subject to the Preliminary DIRs and amended consent order. However, in the event we are ultimately obligated to repair the vehicles subject to current or future Takata DIRs under the amended consent order in the U.S., we estimate a reasonably possible impact to GM of approximately $1.2 billion.

GM has recalled certain vehicles sold outside of the U.S. to replace Takata inflators in those vehicles. There are significant differences in vehicle and inflator design between the relevant vehicles sold internationally and those sold in the U.S. We continue to gather and analyze evidence about these inflators and to share our findings with regulators. Additional recalls, if any, could be material to our results of operations and cash flows. We continue to monitor the international situation.

There are several putative class actions that have been filed against GM, including in the federal courts in the U.S., in the Provincial Courts in Canada, and in Mexico and Israel, arising out of allegations that airbag inflators manufactured by Takata are defective. At this early stage of these proceedings, we are unable to provide an evaluation of the likelihood that a loss will be incurred or an estimate of the amounts or range of possible loss.

Opel/Vauxhall Sale In 2017 we sold the Opel and Vauxhall businesses and certain other assets in Europe (the Opel/Vauxhall Business) to PSA Group. We also sold the European financing subsidiaries and branches (the Fincos, and together with the Opel/Vauxhall Business, the European Business) to Banque PSA Finance S.A. and BNP Paribas Personal Finance S.A. Our wholly owned subsidiary (the Seller) agreed to indemnify PSA Group for certain losses resulting from any inaccuracy of the representations and warranties or breaches of our covenants included in the Master Agreement (the Agreement) and for certain other liabilities, including certain emissions and product liabilities. The Company entered into a guarantee for the benefit of PSA Group and pursuant to which the Company agreed to guarantee the Seller's obligation to indemnify PSA Group. Certain of these indemnification obligations are subject to time limitations, thresholds and/or caps as to the amount of required payments.

Although the sale reduced our new vehicle presence in Europe, we may still be impacted by actions taken by regulators related to vehicles sold before the sale. In Germany, the Kraftfahrt-Bundesamt (KBA) issued an order in November 2019, which converted a voluntary recall initiated by Opel in 2017 and 2018 into a mandatory recall for allegedly failing to comply with certain emissions regulations. However, because the overwhelming majority of vehicles have already received KBA-approved software calibration updates pursuant to the voluntary recall, the number of vehicles subject to the mandatory recall is insignificant. The Seller may also be obligated to indemnify PSA Group or otherwise absorb costs and expenses resulting from the foregoing as well as certain related potential litigation costs, settlements, judgments and potential fines. In addition, at the KBA's request, the German authorities re-opened a separate criminal investigation related to this matter that had previously been closed with no action. We are unable to estimate any reasonably possible loss or range of loss that may result from this matter.

Transactions with PSA We continue to purchase from and supply to PSA Group certain vehicles, parts and engineering services for a period of time following the sale. The following table summarizes transactions with the Opel/Vauxhall Business:

Product Liability We recorded liabilities of $591 million and $544 million in Accrued liabilities and Other liabilities at September 30, 2020 and December 31, 2019 for the expected cost of all known product liability claims, plus an estimate of the expected cost for product liability claims that have already been incurred and are expected to be filed in the future for which we are self-insured. It is reasonably possible that our accruals for product liability claims may increase in future periods in material amounts, although we cannot estimate a reasonable range of incremental loss based on currently available information. Other than claims relating to the ignition switch recalls discussed above, we believe that any judgment against us involving our and MLC products for actual damages will be adequately covered by our recorded accruals and, where applicable, excess liability insurance coverage.

Guarantees We enter into indemnification agreements for liability claims involving products manufactured primarily by certain joint ventures. These guarantees terminate in years ranging from 2020 to 2025 or upon the occurrence of specific events or are ongoing. We believe that the related potential costs incurred are adequately covered by our recorded accruals, which are insignificant. The maximum future undiscounted payments mainly based on vehicles sold to date were $3.2 billion and $2.6 billion for these guarantees at September 30, 2020 and December 31, 2019, the majority of which relates to the indemnification agreements.

We provide payment guarantees on commercial loans outstanding with third parties such as dealers. In some instances, certain assets of the party or our payables to the party whose debt or performance we have guaranteed may offset, to some degree, the amount of any potential future payments. We are also exposed to residual value guarantees associated with certain sales to rental car companies.

We periodically enter into agreements that incorporate indemnification provisions in the normal course of business. It is not possible to estimate our maximum exposure under these indemnifications or guarantees due to the conditional nature of these obligations. Insignificant amounts have been recorded for such obligations as the majority of them are not probable or estimable at this time and the fair value of the guarantees at issuance was insignificant. Refer to the Opel/Vauxhall Sale section of this note for additional information on our indemnification obligations to PSA Group under the Agreement.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year-to-date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2011 to 2019 with various significant tax jurisdictions. In the three months ended September 30, 2020, Income tax expense of $887 million was primarily due to tax expense attributable to entities included in our effective tax rate calculation. In the three months ended September 30, 2019, Income tax expense of $271 million was primarily due to tax expense attributable to entities included in our effective tax rate calculation, partially offset by U.S. tax benefits from foreign activity. In the nine months ended September 30, 2020, Income tax expense of $1.1 billion was primarily due to tax expense attributable to entities included in our effective tax rate calculation and the establishment of a valuation allowance against deferred tax assets. In the nine months ended September 30, 2019, Income tax expense of $932 million was primarily due to tax expense attributable to entities included in our effective tax rate calculation, partially offset by U.S. tax benefits from foreign activity, tax settlements and a release of valuation allowance. At September 30, 2020, we had $23.4 billion of net deferred tax assets consisting of net operating losses and income tax credits, capitalized research expenditures and other timing differences that are available to offset future income tax liabilities, partially offset by valuation allowances.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Restructuring and Other Initiatives

Restructuring and Related Activities [Abstract]

Restructuring and Other Initiatives

We have executed various restructuring and other initiatives and we may execute additional initiatives in the future, if necessary, to streamline manufacturing capacity and reduce other costs to improve the utilization of remaining facilities. To the extent these programs involve voluntary separations, a liability is generally recorded at the time offers to employees are accepted. To the extent these programs provide separation benefits in accordance with pre-existing agreements, a liability is recorded once the amount is probable and reasonably estimable. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Related charges are recorded in Automotive and other cost of sales and Automotive and other selling, general and administrative expense.

The following table summarizes the reserves and charges related to restructuring and other initiatives, including postemployment benefit reserves and charges:

In the three and nine months ended September 30, 2020, restructuring and other initiatives primarily included actions in GMI related to the wind-down of Holden sales, design and engineering operations in Australia and New Zealand and the execution of definitive agreements to sell our vehicle and powertrain manufacturing facilities in Thailand. We recorded charges of $76 million in the three months ended September 30, 2020, primarily for supplier claims. We recorded charges of $657 million in the nine months ended September 30, 2020, primarily consisting of $367 million in property and intangible asset impairments, inventory provisions, sales allowances and other charges, not reflected in the table above, and $290 million in dealer restructurings and employee separation charges, which are reflected in the table above. We also recorded a $236 million charge to Income tax expense due to the establishment of a valuation allowance against deferred tax assets in Australia and New Zealand in the nine months ended September 30, 2020. We incurred $222 million in net cash outflows resulting from these restructuring actions, primarily for dealer restructuring payments and employee separation payments in the nine months ended September 30, 2020. We expect to incur additional restructuring and other charges of an insignificant amount and additional net cash outflows of approximately $40 million, which includes expected proceeds of approximately $140 million from the sale of our manufacturing facility in Thailand, to be substantially complete by the end of 2020.

In the three and nine months ended September 30, 2019, restructuring and other initiatives primarily included actions related to our announced transformation activities, which includes the unallocation of products to certain manufacturing facilities and other employee separation programs. We recorded charges of $390 million, primarily in GMNA, in the three months ended September 30, 2019 consisting of $209 million primarily in pension curtailment and other charges, which are not reflected in the table above, and $181 million primarily in supplier-related charges, reflected in the table above. We recorded charges of $1.5 billion, primarily in GMNA, in the nine months ended September 30, 2019 consisting of $1.1 billion primarily in non-cash accelerated depreciation and pension curtailment and other charges, not reflected in the table above, and $421 million primarily in supplier-related charges, which are reflected in the table above. These programs had a total cost since inception of $3.1 billion and were complete at December 31, 2019. We incurred $314 million and $645 million in cash outflows resulting from these restructuring actions in the nine months ended September 30, 2020 and 2019 and $1.4 billion in cash outflows since program inception, primarily for employee separation payments and supplier-related payments. We expect additional cash outflows related to these activities of approximately $100 million.

Stockholders' Equity Note [Abstract]

Stockholders' Equity and Noncontrolling Interests

We have 2.0 billion shares of preferred stock and 5.0 billion shares of common stock authorized for issuance. We had no shares of preferred stock and 1.4 billion shares of common stock issued and outstanding at September 30, 2020 and December 31, 2019.

GM Financial Preferred Stock In September 2020, GM Financial issued $500 million of Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series C, $0.01 par value, with a liquidation preference of $1,000 per share.

Segment Reporting

Segment Reporting [Abstract]

Segment Reporting

We analyze the results of our business through the following reportable segments: GMNA, GMI, Cruise and GM Financial. The chief operating decision maker evaluates the operating results and performance of our automotive segments and Cruise through earnings before interest and income taxes (EBIT)-adjusted, which is presented net of noncontrolling interests. The chief operating decision maker evaluates GM Financial through earnings before income taxes (EBT)-adjusted because interest income and interest expense are part of operating results when assessing and measuring the operational and financial performance of the segment. Each segment has a manager responsible for executing our strategic initiatives. While not all vehicles within a segment are individually profitable on a fully allocated cost basis, those vehicles attract customers to dealer showrooms and help maintain sales volumes for other, more profitable vehicles and contribute towards meeting required fuel efficiency standards. As a result of these and other factors, we do not manage our business on an individual brand or vehicle basis.

Substantially all of the trucks, crossovers, cars and automobile parts produced are marketed through retail dealers in North America and through distributors and dealers outside of North America, the substantial majority of which are independently owned. In addition to the products sold to dealers for consumer retail sales, trucks, crossovers and cars are also sold to fleet customers, including daily rental car companies, commercial fleet customers, leasing companies and governments. Fleet sales are completed through the dealer network and in some cases directly with fleet customers. Retail and fleet customers can obtain a wide range of after-sale vehicle services and products through the dealer network, such as maintenance, light repairs, collision repairs, vehicle accessories and extended service warranties.

GMNA meets the demands of customers in North America with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet and GMC brands. GMI primarily meets the demands of customers outside North America with vehicles developed, manufactured and/or marketed under the Buick, Cadillac, Chevrolet, GMC and Holden brands. We also have equity ownership stakes in entities that meet the demands of customers in other countries, primarily China, with vehicles developed, manufactured and/or marketed under the Baojun, Buick, Cadillac, Chevrolet and Wuling brands. Cruise is our global segment responsible for the development and commercialization of autonomous vehicle technology, and includes autonomous vehicle-related engineering and other costs.

Our automotive interest income and interest expense, legacy costs from the Opel/Vauxhall Business (primarily pension costs), corporate expenditures and certain nonsegment-specific revenues and expenses are recorded centrally in Corporate.

Corporate assets primarily consist of cash and cash equivalents, marketable debt securities, PSA warrants and intercompany balances. Retained net underfunded pension liabilities related to the European Business are also recorded in Corporate. All intersegment balances and transactions have been eliminated in consolidation.

The following tables summarize key financial information by segment:

Nature of Operations and Basis of Presentation (Policies)	9 Months Ended

Nature of Operations and Basis of Presentation [Abstract]
Basis of Accounting	The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements include all adjustments, which consist of normal recurring adjustments and transactions or events discretely impacting the interim periods, considered necessary by management to fairly state our results of operations, financial position and cash flows. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2019 Form 10-K. Except for per share amounts or as otherwise specified, dollar amounts presented within tables are stated in millions.
Principles of Consolidation	Principles of Consolidation We consolidate entities that we control due to ownership of a majority voting interest and we consolidate variable interest entities (VIEs) when we are the primary beneficiary. Our share of earnings or losses of nonconsolidated affiliates is included in our consolidated operating results using the equity method of accounting when we are able to exercise significant influence over the operating and financial decisions of the affiliate.
Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards Effective January 1, 2020, we adopted Accounting Standards Update (ASU) 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" (ASU 2016-13), which requires entities to use a new impairment model based on current expected credit losses (CECL) rather than incurred losses. Estimated credit losses under CECL consider relevant information about past events, current conditions and reasonable and supportable forecasts that affect the collectability of financial assets, resulting in recognition of lifetime expected credit losses at initial recognition of the related asset. We adopted ASU 2016-13 on a modified retrospective basis by recognizing an after-tax cumulative-effect adjustment to the opening balance of Retained earnings of $660 million, inclusive of $643 million related to GM Financial. The application of ASU 2016-13 increased our allowance for loan losses related to GM Financial receivables, net by $801 million and had an insignificant impact to our allowance for credit losses for Accounts and notes receivable and no adoption impact to Marketable debt securities on our condensed consolidated balance sheets. In March 2020, the Financial Accounting Standards Board issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), which provides optional expedients and exceptions for applying U.S. GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. We do not believe the discontinuance of LIBOR will be a significant event for our Automotive arrangements. A substantial portion of GM Financial’s indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. Effective July 1, 2020, we adopted ASU 2020-04 on a prospective basis. The adoption of, and future elections under, ASU 2020-04 are not expected to have a material impact on our condensed consolidated financial statements as the standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on GM Financial's contracts, hedging relationships and other transactions.
Marketable Debt Securities	Marketable Debt Securities We classify marketable debt securities as either available-for-sale or trading. Various factors, including turnover of holdings and investment guidelines, are considered in determining the classification of securities. Available-for-sale debt securities are recorded at fair value with unrealized gains, and losses that are not credit related, recorded net of applicable taxes in Accumulated other comprehensive loss until realized. Credit losses are recorded in Interest income and other non-operating income, net. An evaluation is made quarterly to determine if any portion of unrealized losses on available-for-sale debt securities is related to credit losses or whether any unrealized losses recorded in Accumulated other comprehensive loss need to be reclassified. Non-credit related unrealized losses are reclassified to Interest income and other non-operating income, net if we intend to sell the security or it is more likely than not that we will be required to sell the security before the recovery of the unrealized loss.
Accounts and Notes Receivable	Accounts and Notes Receivable Accounts and notes receivable primarily consists of amounts that are due and payable from our customers for the sale of vehicles, parts, and accessories. We evaluate the collectability of receivables each reporting period and record an allowance for doubtful accounts to present the net amount expected to be collected on our receivables. Additions to the allowance are charged to bad debt expense and reported in Automotive and other selling, general and administrative expense.
GM Financial Receivables	GM Financial Receivables Finance receivables are carried at amortized cost, net of allowance for loan losses. Provisions for loan losses are charged to operations in amounts sufficient to maintain the allowance for loan losses at levels considered adequate to cover expected credit losses on the finance receivables. For retail finance receivables, GM Financial uses static pool modeling techniques to determine the allowance for loan losses expected over the remaining life of the receivables, which is supplemented by management judgment. The modeling techniques incorporate reasonable and supportable forecasts of economic conditions over the expected remaining life of the finance receivables. The economic forecasts incorporate factors which vary by region that GM Financial believes will have the largest impact on expected losses, including unemployment rates, interest rate spreads, disposable personal income and growth rates in gross domestic product. Troubled debt restructurings (TDRs) are grouped separately for purposes of measuring the allowance. The allowance for TDRs uses static pool modeling techniques like non-TDR retail finance receivables to determine the expected loss amount. The expected cash flows of the receivables are then discounted at the original weighted average effective interest rate of the pool. Factors considered when estimating the allowance for TDRs are based on an evaluation of historical and current information, which may be supplemented by management judgment. Finance charge income from loans classified as TDRs is accounted for in the same manner as other accruing loans. Cash collections on these loans are allocated according to the same payment hierarchy methodology applied to loans that are not classified as TDRs. Commercial finance receivables are carried at amortized cost, net of allowance for loan losses and any amounts held under a cash management program. GM Financial establishes the allowance for loan losses based on historical loss experience, as well as the forecast for industry vehicle sales, which is the economic indicator believed to have the largest impact on expected losses.
