On [XXX]. My car went into unintended acceleration at full throttle of 8000 RPMs. The engine was stuck at maximum power and would not slow down. My car slide until it hit a curb and was forced to stop. However, the engine was still running at full maximum capacity at full unintended acceleration. My [XXX] son had to go to ER and it almost cost the lives of 4 other people. I am very scared to ever drive this car as it is now a threat to safety for everyone driving near this car. Please report this to the BMW NA manufacturer since they have their engineering looking at the vehicle. Please call me with a resolution at [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint 11710392 - Filed Dec 30, 2025Failure Dec 26, 2025Newark, DEFuel/propulsion system
Engine misfire and loss of power. Too to bmw for check up. It was coolant tank leak into injectors. BMW is not replacing the tank as part of recall. It is changing only injectors even though the recall specifically addresses the tank causing the issue. BMW argument is as part of recall this was checked and tank was fine so not replaced as part or recall. Now it is not under warranty. Why are they repairing injectors if the tank car is not under warranty they should replace the tank also as it is the bad part causing this. The car has only 14k miles.
NHTSA complaint 11707818 - Filed Dec 11, 2025Failure Dec 3, 2025Irvine, CAAutomatic emergency braking, Service brakes, Vehicle speed control
While driving, the vehicle immediately went into full unintended acceleration without any input from the accelerator pedal. I removed my foot completely from the pedal, but engine RPM increased to full 7000 rpm’s and the throttle was stuck there. The vehicle surged forward unexpectedly. The car spun in circles 180 degrees and wouldn’t stop. This was a sudden and unpredictable event. This created safety concerns for my [XXX] old and and we had to take him to the ER for his head injury. The car hit curbs and jumped onto the opposite side of traffic. BMW Dealer is currently opening a BMW STI case to investigate potential throttle or electronic control issues.
