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 was incorporated as a Delaware corporation in 2009. We design, build and sell trucks, crossovers, cars and automobile parts and provide software-enabled services and subscriptions worldwide. We also provide automotive financing services through GM Financial. We analyze the results of our operations through the following segments: GMNA, GMI, Cruise and GM Financial. Cruise is our global segment responsible for the development of AV technology. Corporate includes certain centrally recorded income and costs such as interest, income taxes, corporate expenditures and certain revenues and expenses that are not part of a reportable segment. The consolidated financial statements are prepared in conformity with U.S. GAAP. Except for per share amounts or as otherwise specified, amounts presented within tables are stated in millions. Certain columns and rows may not add due to rounding. Throughout this report, we refer to General Motors Company and its consolidated subsidiaries in a simplified manner and on a collective basis, using words like "we", "our", "us" and "the Company." This drafting style is suggested by the SEC and is not meant to indicate that General Motors Company, the publicly traded parent company, or any particular subsidiary of the parent company, owns or operates any particular asset, business or property. The operations and businesses described in this report are owned and operated by distinct subsidiaries of General Motors Company. 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 are 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. Use of Estimates in the Preparation of the Financial Statements Accounting estimates are an integral part of the consolidated financial statements. These estimates require the use of judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and the resulting balances are reasonable; however, due to the inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in future periods. GM Financial The amounts presented for GM Financial are 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.
