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, NHTSA 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

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2022 BMW 8 Series Convertible verdict →
