Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We were lucky. The accelerator not only stuck, but snapped down against the floor board. Luckily, I was driving, not my 70+ year old mother, and we were on an open road with no people or objects in front of us. Even so, we were doing appox. 80 MPH before I put it in neutral and shut off the key. The dealership did a good job. They discovered that the wiring harness at lighting control module had somehow gotten into the accelerator mechanism causing the gas pedal to stick down. …”
NHTSA complaint #760127, filed 2002-04“Consumer could not get the vehicle to start. Once started consumer proceeded across the lot. Consumer stopped the car and when getting back in could not get it out of gear until after turning the motor off. As consumer approached the traffic light, he used the brakes to slow to a stop. All of a sudden, the vehicle jolted forward out of control.”
NHTSA complaint #567030, filed 2002-08“While slowing down to stop without any indication vehicle idles to 40 MPH. Consumer depressed brakes with force and vehicle idled low. Dealer has been contacted. Please provide further information.”
