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 segments: GM North America (GMNA), GM International (GMI), Cruise, and GM Financial. 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 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 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 2020 Form 10-K. Except for per share amounts or as otherwise specified, 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. All intercompany balances and transactions have been eliminated in consolidation. 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. GM Financial The amounts presented for GM Financial have been adjusted to reflect the impact on GM Financial's deferred tax positions and provision for income taxes resulting from the inclusion of GM Financial in our consolidated tax return and to eliminate the effect of transactions between GM Financial and the other members of the consolidated group. Accordingly, the amounts presented will differ from those presented by GM Financial on a stand-alone basis.

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 $538 million and $714 million at March 31, 2021 and December 31, 2020.

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. There were no commercial finance receivables on nonaccrual status at March 31, 2021. GM Financial's commercial risk model and 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 tables summarize the credit risk profile by dealer risk rating of commercial finance receivables at March 31, 2021 and December 31, 2020: Year of Origination(a) March 31, 2021 Revolving 2021 2020 2019 2018 2017 Prior Total Percent I $ 5,206 $ 106 $ 473 $ 134 $ 53 $ 91 $ 50 $ 6,113 91.1 % II 346 2 2 17 1 3 10 381 5.7 % III 149 9 4 8 28 2 15 215 3.2 % IV 1 — — — — — — 1 — % Commercial finance receivables, net of fees $ 5,702 $ 117 $ 479 $ 159 $ 82 $ 96 $ 75 $ 6,710 100.0 % __________ (a) Floorplan advances comprise 94% of the total revolving balance.

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities Consolidated VIEs Automotive Financing- GM Financial 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: March 31, 2021 December 31, 2020 Restricted cash – current $ 2,488 $ 2,190 Restricted cash – non-current $ 476 $ 449 GM Financial receivables, net of fees – current $ 14,840 $ 17,211 GM Financial receivables, net of fees – non-current $ 14,485 $ 15,107 GM Financial equipment on operating leases, net $ 17,461 $ 16,322 GM Financial short-term debt and current portion of long-term debt $ 18,228 $ 20,450 GM Financial long-term debt $ 21,381 $ 18,974 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 loan losses expected over the remaining life of the finance receivables. Nonconsolidated VIEs Automotive Nonconsolidated VIEs principally include automotive related operating entities to which we provided financial support to ensure that our supply needs for production are met or are not disrupted. Our variable interests in these nonconsolidated VIEs include equity investments, accounts and loans receivable, committed financial support and other off-balance sheet arrangements. The carrying amounts of assets and liabilities related to our nonconsolidated VIEs were insignificant at March 31, 2021 and December 31, 2020. Our maximum exposure to loss as a result of our involvement with these VIEs was $1.2 billion, inclusive of $676 million and $776 million in committed capital contributions to Ultium Cells LLC at March 31, 2021 and December 31, 2020. We currently lack the power through voting or similar rights to direct the activities of these entities that most significantly affect their economic performance.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 March 31, 2021 and December 31, 2020, we had accruals of $1.1 billion and $1.2 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. GM Korea Wage Litigation GM Korea Company (GM Korea) is party to litigation with current and former salaried employees over whether to include fixed bonuses in the calculation of Ordinary Wages due under Korean regulations. In 2017, the Seoul High Court (an intermediate-level appellate court) held that certain workers are not barred from filing retroactive wage claims. GM Korea appealed this ruling to the Supreme Court of the Republic of Korea (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 approximate ly $180 million at March 31, 2021. 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 and September 2020 orders. In June 2020, the Seoul High Court ruled against GM Korea in one of the subcontract worker claims. GM Korea has appealed this decision to the Korean Supreme Court. At March 31, 2021, our accrual covering certain asserted claims and claims that we believe are probable of assertion and for which liability is probable was approximately $250 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 $120 million at March 31, 2021. 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 that granted the Company the right to recover certain taxes collected by the government. As a result, GM Brazil recorded pre-tax recoveries of $1.4 billion in the year ended December 31, 2019 and we are currently realizing the recoveries as we have federal tax liabilities eligible for offset. A Motion of Clarification has been filed by the Brazilian IRS with the Brazilian Supreme Court and it is scheduled for decision in May 2021. We expect third parties will file claims asserting challenges, including entitlements, to some or all of the tax recoveries awarded and recognized by GM, and GM intends to defend against any such claims if they are filed. 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 ar e several putat ive class actions pending against GM in federal courts in the U.S. and in the Provincial Courts in Canada 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 b e reasonably estimated at March 31, 2021. 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 approxima tely $800 million at March 31, 2021. Takata Matters In November 2020, the National Highway Traffic Safety Administration (NHTSA) directed that we replace the airbag inflators in our GMT900 vehicles, which are full-size pickup trucks and sport utility vehicles (SUVs), and we decided not to contest NHTSA's decision. While we have already begun the process of executing the recall, given the number of vehicles in this population, the recall will take several years to be completed. Accordingly, in the three months ended December 31, 2020, we recorded a warranty accrual of $1.1 billion for the expected costs of complying with the recall remedy, and we believe the currently accrued amount remains reasonable. 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. Any additional recalls relating to these inflators could be material to our results of operations and cash flows. 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 stage of these proceedings, we are unable to provide 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 (now Stellantis as a result of the merger of PSA Group and Fiat Chrysler Automobiles N.V. on January 16, 2021) under a Master Agreement (the Agreement). 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. 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. Our wholly owned subsidiary (the Seller) agreed to indemnify Stellantis for certain losses resulting from any inaccuracy of the representations and warranties or breaches of our covenants included in the Agreement and for certain other liabilities, including certain emissions and product liabilities. The Company entered into a guarantee for the benefit of Stellantis and pursuant to which the Company agreed to guarantee the Seller's obligation to indemnify Stellantis. Certain of these indemnification obligations are subject to time limitations, thresholds and/or caps as to the amount of required payments. Product Liability We recorded liabilitie s of $588 million an d $589 million in Accrued liabilities and Other liabilities at March 31, 2021 and December 31, 2020 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. We believe that any judgment against us involving our 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 liabili ty claims involving products manufactured primarily by certain joint ventures. These guarantees terminate in years ranging from 2021 to 2026 or upon the occurrence of specific events or are ongoing. We believe that the related potential costs incurred are adequately covere d by our recorded accruals, which are insignificant. The maximum future undiscounted payments mainly based on vehicles sold to date were $3.2 billion and $3.1 billion for these guarantees at March 31, 2021 and December 31, 2020, 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 p eriodically 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 Stellantis under the Agreement.

Income Taxes

Income Taxes	3 Months Ended
	Mar. 31, 2021
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. In the three months ended March 31, 2021, Income tax expense of $1.2 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 Cruise deferred tax assets that are considered no longer realizable. In the three months ended March 31, 2021, Cruise issued new preferred shares to investors. As a result of the issuance, Cruise fell below the ownership threshold required for inclusion in our U.S. consolidated income tax returns, and we established a valuation allowance of $316 million against deferred tax assets. Refer to Note 16 to our condensed consolidated financial statements for additional information regarding the Cruise preferred stock issuance. The effective tax rate is higher than the applicable statutory tax rate primarily due to tax expense related to the establishment of the valuation allowance. In the three months ended March 31, 2020, Income tax expense of $357 million 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 that were considered no longer realizable. The effective tax rate was higher than the applicable statutory tax rate primarily due to tax expense related to the establishment of the valuation allowance and losses for which a tax benefit cannot be realized. At March 31, 2021, we had $22.4 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.

Restructuring and Other Initiat

Restructuring and Other Initiatives	3 Months Ended

Restructuring and Related Activities [Abstract]
Restructuring and Other Initiatives	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: Three Months Ended March 31, 2021 March 31, 2020 Balance at beginning of period $ 352 $ 564 Additions, interest accretion and other 3 219 Payments (79) (175) Revisions to estimates and effect of foreign currency (1) (25) Balance at end of period $ 275 $ 583 In the three months ended March 31, 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 binding term sheets to sell our vehicle and powertrain manufacturing facilities in Thailand. We recorded charges of $489 million in the three months ended March 31, 2020, primarily consisting of $270 million in asset impairments related to property, inventory provisions and intangibles and sales allowances and other charges, not reflected in the table above, and $219 million in dealer restructurings and employee separation charges, which are reflected in the table above. These programs, including the execution of a binding term sheet to sell our manufacturing facility in India, had a total cost since inception of $687 million. We also recorded a $236 million charge to Income tax expense due to the establishment of a valuation allowance against deferred tax assets that are considered no longer realizable in Australia and New Zealand in the three months ended March 31, 2020. We incurred insignificant cash outflows resulting from these restructuring actions in the three months ended March 31, 2021 and 2020, and $221 million in net cash outflows since program inception, primarily for dealer restructuring payments and employee separation payments, which includes proceeds of $143 million from the sale of our manufacturing facilities in Thailand.

Stockholders' Equity Note [Abstract]
Stockholders' Equity and Noncontrolling Interests	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 issued and outstanding, 1.5 billion and 1.4 billion shares of common stock issued and 1.4 billion shares of common stock outstanding at March 31, 2021 and December 31, 2020. Cruise Preferred Shares In the three months ended March 31, 2021, GM Cruise Holdings LLC (Cruise Holdings) issued $2.5 billion of Class G Preferred Shares (Cruise Class G Preferred Shares) to Microsoft Corporation (Microsoft) and certain other investors, including $1.0 billion to General Motors Holdings LLC. All proceeds related to the Cruise Class G Preferred Shares are designated exclusively for working capital and general corporate purposes of Cruise Holdings. In addition, we, Cruise Holdings and Microsoft entered into a long-term strategic relationship to accelerate the commercialization of self-driving vehicles with Microsoft being the preferred public cloud provider. The Cruise Class G Preferred Shares participate pari passu with holders of Cruise Holdings common stock and Cruise Class F Preferred Shares in any dividends declared. Each Cruise Class G Preferred Share is entitled to one vote per Cruise Class G Preferred Share on all matters submitted for vote by or consent of the Cruise Holdings members. The holders of Cruise Class G Preferred Shares are restricted from transferring the Cruise Class G Preferred Shares for four years, without the written consent of both us and Cruise Holdings' Board of Directors. The Cruise Class G Preferred Shares convert into the class of shares to be issued to the public in an IPO at specified exchange ratios. No covenants or other events of default exist that can trigger redemption of the Cruise Class G Preferred Shares. The Cruise Class G Preferred Shares are entitled to receive the greater of their carrying value or a pro-rata share of any proceeds or distributions upon the occurrence of a merger, sale, liquidation or dissolution of Cruise Holdings, and are classified as noncontrolling interests in our condensed consolidated financial statements. Consistent with the Cruise Class G Preferred Shares, the Class A-1 Preferred Shares issued to SoftBank in 2018 (Cruise Class A-1 Preferred Shares) and Cruise Class F Preferred Shares convert into the class of shares to be issued to the public in an IPO at specified exchange ratios. Beginning on June 28, 2025, SoftBank has the option to convert all of the Cruise Class A-1 Preferred Shares into our common stock at a conversion ratio that is indexed to the fair value of Cruise Holdings at the time of conversion. In the event SoftBank exercises such option, we have the option to settle the conversion feature with our common shares or cash, and in certain situations with nonredeemable, nonconvertible preferred shares. The Cruise Class A-1 Preferred Shares and Cruise Class F Preferred Shares are entitled to receive the greater of their carrying value or a pro-rata share of any proceeds or distributions upon the occurrence of a merger, sale, liquidation, or dissolution of Cruise Holdings.

Segment Reporting

Segment Reporting	3 Months Ended

Segment Reporting [Abstract]
Segment Reporting	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 and GMC 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, Stellantis 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: At and For the Three Months Ended March 31, 2021 GMNA GMI Corporate Eliminations Total Automotive Cruise GM Financial Eliminations/Reclassifications Total Net sales and revenue $ 25,957 $ 3,086 $ 19 $ 29,062 $ 30 $ 3,407 $ (25) $ 32,474 Earnings (loss) before interest and taxes-adjusted $ 3,134 $ 308 $ 30 $ 3,472 $ (229) $ 1,182 $ (8) $ 4,417 Adjustments $ — $ — $ — $ — $ — $ — $ — — Automotive interest income 32 Automotive interest expense (250) Net (loss) attributable to noncontrolling interests (8) Income before income taxes 4,191 Income tax expense (1,177) Net income 3,014 Net loss attributable to noncontrolling interests 8 Net income attributable to stockholders $ 3,022 Equity in net assets of nonconsolidated affiliates $ 355 $ 6,994 $ — $ — $ 7,349 $ — $ 1,630 $ — $ 8,979 Goodwill and intangibles $ 2,320 $ 796 $ — $ — $ 3,116 $ 730 $ 1,339 $ — $ 5,185 Total assets $ 113,926 $ 22,798 $ 36,271 $ (53,147) $ 119,848 $ 5,324 $ 114,597 $ (1,358) $ 238,411 Depreciation and amortization $ 1,198 $ 132 $ 6 $ — $ 1,336 $ 11 $ 1,668 $ — $ 3,015 Impairment charges $ — $ — $ — $ — $ — $ — $ — $ — $ — Equity income $ 4 $ 307 $ — $ — $ 311 $ — $ 54 $ — $ 365 At and For the Three Months Ended March 31, 2020 GMNA GMI Corporate Eliminations Total Automotive Cruise GM Financial Eliminations/Reclassifications Total Net sales and revenue $ 25,831 $ 3,280 $ 38 $ 29,149 $ 25 $ 3,561 $ (26) $ 32,709 Earnings (loss) before interest and taxes-adjusted $ 2,194 $ (551) $ (411) $ 1,232 $ (228) $ 230 $ 16 $ 1,250 Adjustments(a) $ — $ (489) $ — $ (489) $ — $ — $ — (489) Automotive interest income 83 Automotive interest expense (193) Net (loss) attributable to noncontrolling interests (8) Income before income taxes 643 Income tax expense (357) Net income 286 Net loss attributable to noncontrolling interests 8 Net income attributable to stockholders $ 294 Equity in net assets of nonconsolidated affiliates $ 93 $ 5,991 $ — $ — $ 6,084 $ — $ 1,437 $ — $ 7,521 Goodwill and intangibles $ 2,432 $ 820 $ 1 $ — $ 3,253 $ 634 $ 1,338 $ — $ 5,225 Total assets $ 109,159 $ 23,213 $ 45,965 $ (49,766) $ 128,571 $ 4,069 $ 115,381 $ (1,397) $ 246,624 Depreciation and amortization $ 1,227 $ 166 $ 9 $ — $ 1,402 $ 8 $ 1,788 $ — $ 3,198 Impairment charges $ 20 $ 90 $ — $ — $ 110 $ — $ — $ — $ 110 Equity income (loss) $ 6 $ (163) $ — $ — $ (157) $ — $ 25 $ — $ (132) __________ (a) Consists of restructuring and other charges in Australia, New Zealand and Thailand.

Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The 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 2020 Form 10-K. Except for per share amounts or as otherwise specified, 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. All intercompany balances and transactions have been eliminated in consolidation. 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.
GM Financial	GM Financial The amounts presented for GM Financial have been adjusted to reflect the impact on GM Financial's deferred tax positions and provision for income taxes resulting from the inclusion of GM Financial in our consolidated tax return and to eliminate the effect of transactions between GM Financial and the other members of the consolidated group. Accordingly, the amounts presented will differ from those presented by GM Financial on a stand-alone basis.
