Owner report 11704468 · 2025-12-11 (December 11, 2025)
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 tra…

Owner report 11707818 · 2025-12-30 (December 30, 2025)

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 …

Please report this to the BMW NA manufacturer since they ha…
