Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The tachometer of the car sticks in high revs (1500-2500),engine on, car in neutral, foot off the gas pedal, if the car is moving over 20-25mph (either by free falling a hill or being pulled) the tachometer varies the RPM reading to match speed just as if the car would be in 'd' position. I think the ecu has a glitch of some sort that ignores the gas pedal and the shift position if the car is moving.
