Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While stopped at a stop light vehicle RPM went very high. It reached the red zone. Vehicle started moving forward (while still on Drive and the brake pedal fully pressed). I immediately put the vehicle in Park. RPM continued to remain high. I removed my foot off the brake when the vehicle was in park. I turned the engine off, waited couple of seconds and turned it back on. At that point everything worked normally. Outside temperature was about 38 deg F. Car was not fully warmed up at the time. Floor mat had nothing to do with this incident. …”
