Defect investigations
Driveshaft to rear differential connection failure
The Office of Defects Investigation (ODI) received a petition on September 1, 2026 (dated August 5, 2026), requesting an investigation into an alleged defect in BMW rear differential assemblies. The petitioner alleges Model Year (MY) 2022 BMW 540i vehicles are experiencing a sudden mechanical failure that severs the drive connection between the driveshaft and the rear wheels. On August 12, 2026, BMW filed Safety Recall 26V525, which addresses the same condition raised in the petition. and covers certain 2022-2026 840i, 840i xDrive, 2021-2023 540i, 540i xDrive, M550i xDrive, and 2024-2026 750e xDrive vehicles. This safety recall addresses potential wear in the connection between the rear driveshaft and rear differential, which could cause the connection to fail. The Vehicle Identification Number included in the petition falls within BMWâs recall scope and subject to BMWâs reimbursement program. Because Safety Recall 26V525 fully addresses the concerns raised in the petition, further investigation is unnecessary. Therefore, ODI is denying this Defect Petition and closing this action. The agency will continue to monitor the remedy and reserves the right to take any action if warranted by future circumstances.

Most recent owner complaints, unedited.
The contact owns a 2022 BMW 840I. The contact received notification of the federal safety agency Campaign Number: 25V644000 (Electrical System) in 2025.

In September 2025, BMW issued a recall # 25V644 for a safety related potential fire issue on the starter for my 2022 840i Gran Coupe. It has now been 4 months, and BMW is still telling me they do not have the assigned parts to resolve this issue. Furthermore, the federal safety agency has somehow dropped this recall off the records for the VIN of my car, which is troubling. My compliant is BMW is not timely in their efforts to correct a safety fire issue for my vehicle.
Customer filing a complaint against BMW for untimely resolution of Recall #25V644. This recall is a known Safety Risk which began in the summer of 2025. It is now December 4, 2025, and discussions today with BMW North America, they cannot provide me an ETA of when parts will be available for my vehicle. Further info from BMW North America says they will mail me a letter sometime? in 2026 to tell me when parts are available but if I have electrical heating/smoke issues before that to take the car to the BMW Dealer. BMW appears to be pretty nonchalant about this recall and can't provide timing to resolve the serious nature of a fire being the result of this recall's safety risk. Very disappointing.

Safety was compromised by drivetrain instability and a federal recall involving a starter motor defect that poses a fire risk. Despite this, BMW of Arlington has refused to authorize repairs or allow BMW of Austin to complete the necessary work—even after a $13,565 drivetrain failure diagnosis. On October 4, 2025, our 2022 BMW 840i became inoperable due to worn splines in the rear differential and drive shaft. BMW of Austin confirmed the failure was consistent with prior service-induced damage. The component is available for inspection. The issue followed a July 24 oil change at BMW of Arlington, after which the vehicle became undriveable. Staff verbally admitted damaging a plastic part but provided no technician report. A loaner vehicle was issued, implying acknowledgment of faultThe problem was confirmed by BMW of Austin. BMW of Arlington has not inspected the failed component and stated they “do not know what caused it.” No inspection has been performed by the manufacturer, police, or insurance representatives. Prior symptoms included persistent tire pressure issues, a visibly bent rim, and a failed emissions test dated October 28, 2022—before our purchase. The vehicle was titled at 21,248 miles but listed days later at 41,418 and 48,290 miles, triggering a NMVTIS “possible odometer rollback” alert. Following our escalation to BMW Group CEO [XXX] , our BMW app was restricted and warranty data—including federally protected emissions coverage—was removed. This suggests retaliatory suppression of coverage visibility. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The Gear Shift area flawed design and defective assembly allows fluid spill to short out transmission and shifting ability. Assembly is not sealed correctly which allows a spilled fluid to leak through the gearshift on and into the the GWS. The GWS was not sealed causing a short in the the assembly & the need for its replacement at substantial cost to the owner. The drink holder is place next to gearshift area with no consideration that spilled fluid will cause the car to shut down and the GWS replacement. 06/21/2022
