Verbatim excerpts from NHTSA complaints, by component
Vehicle speed control
2 reports1 crash
“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]”
