Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the Consolidated Financial Statements were issued. Insurance Coverage The Company is generally required to maintain certain insurance coverage that, subsequent to December 31, 2023, lapsed due to lack of payment. On May 17, 2024, FF Adventures SPV XVIII LLC (“the Buyer”), a third-party investment firm affiliated with ATW Partners, LLC, purchased $11.9 million of Unsecured Convertible Senior Promissory Note principal from Streeterville. In connection with the purchase and sale, Streeterville assigned and transferred all rights, title and interest to the Buyer clear of any lien, claim, or encumbrance. Subsequent Unsecured Notes On January 2, 2024, the Company issued an unsecured note of $1.3 million to a related party with a due date of April 1, 2024 at 4.27% interest. This note is in default as of the date of these financial statements. On January 9, 2024, the Company issued an unsecured convertible note of $1.5 million to a related party with a due date of April 8, 2024 at 4.27% interest. This note is in default as of the date of these financial statements. Principal and accrued interest are convertible at the option of the related party into either a) Common Stock of the Company at a conversion price per share equal to the closing stock price at the closing of trading day immediately prior to the day on which lender provides conversion notice or b) unsecured convertible notes of the Company pursuant to the terms contained in the Unsecured SPA. On February 14, 2024, the Company issued a convertible unsecured note of $0.3 million to a related party with a due date of May 10, 2024 at 4.27% interest. This note is in default as of the date of these financial statements. The note is convertible, in whole or in part, at the latest closing price of FFIE (“Conversion Price”), into shares of Common Stock of the Company at the option of the related party, at any time and from time to time. The number of Common Stock issuable upon a conversion shall be determined by the quotient obtained by dividing the total amount of interest and principal accrued to be converted by the Conversion Price. Subsequent to December 31, 2023, the Company issued unsecured convertible notes to a third party totaling $12.1 million with due dates ranging from April 25, 2024 through August 19, 2024 at 4.27% interest. Of this amount, $2.5 million is in default as of the date of these financial statements. Principal and accrued interest are convertible at the option of the related party into either a) Common Stock of the Company at a conversion price per share equal to the closing stock price at the closing of trading day immediately prior to the day on which lender provides conversion notice or b) unsecured convertible notes of the Company pursuant to the terms contained in the Unsecured SPA. Subsequent SPA Activity Subsequent to December 31, 2023, the Company received additional funding through the optional SPA loans totaling $8.2 million. In addition, $34.4 million of principal and $19.5 million of interest was converted into 398.6 million shares of FF's Class A Common Stock. Included in this amount is $0.7 million of principal and $0.6 million of interest to a related party activity. These related party conversions were converted into 1.3 million shares of Class A Common Stock. Increase in Authorized Shares On February 5, 2024, the Company filed an amendment to the Company’s Third Amended and Restated Certificate of Incorporation with the office of the Secretary of the State of Delaware to effect an increase in the authorized shares of Common Stock from 154,437,500 to 1,389,937,500. Reverse Stock Split At a special meeting of the Company’s stockholders held on February 5, 2024, the Company’s stockholders approved an amendment to the Company’s Third Amended and Restated Certificate of Incorporation, as amended, to effect a reverse stock split of the Common Stock by a ratio of 1-for-3, with such action to be effected at such time and date, if at all, as determined by the Board within one year after the conclusion of the special meeting and a corresponding reduction in the total number of shares of Common Stock the Company is authorized to issue. On February 23, 2024, the Company filed a second amendment to the Company’s Third Amended and Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to effect this reverse stock split and to set the number of authorized shares of Common Stock to 463,312,500 (which is 1,389,937,500 divided by 3). Pursuant to the Certificate of Amendment, effective as of 5:00 p.m., Eastern Time, on February 29, 2024, every three shares of the issued and outstanding Common Stock was automatically converted into one share of Common Stock, without any change in par value per share and the number of authorized shares of Common Stock was reduced to 463,312,500. The Company’s Class A Common Stock began trading on The Nasdaq Capital Market on a split-adjusted basis at the opening of trading on March 1, 2024. The Class A Common Stock continues trading on the Nasdaq Capital Market under the symbol “FFIE” with a new CUSIP number (307359 703). The Class B Common Stock also has a new CUSIP number (307359802). The Company’s publicly traded warrants continue to be traded on the Nasdaq Capital Market under the symbol “FFIEW” and the CUSIP number for the warrants remains unchanged. However, under the terms of the applicable warrant agreement, the number of shares of Class A Common Stock issuable on exercise of each warrant has been proportionately decreased. Specifically, following the effectiveness of the reverse sock split, every three shares of Class A Common Stock that may be purchased pursuant to the exercise of public warrants now represents one share of Class A Common Stock that may be purchased pursuant to such warrants. Accordingly, for the Company’s warrants trading under the symbol “FFIEW”, every three warrants became exercisable for one share of Class A Common Stock at an exercise price of $2,760.00 per share of Class A Common Stock. Other than what has been disclosed in other footnotes or above, the Company did not identify any subsequent events that would have required adjustment to or disclosure in the Consolidated Financial Statements.
