What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
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.
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.
Fuel pump failed within a minute of initial warning and performance indicating a problem. While driving ~60 mph on the highway, available power dropped to zero within a couple tenths of a mile, *barely* allowing me to move to the shoulder.
Tl* the contact owns a 2020 bmw m8. The contact stated that while driving in the rain at 55 mph, the windshield became foggy. The contact activated the defroster/defogger however, failed to immediately clear the windshield. The contact pulled over and waited for the windshield to clear up.
