43 reports3 crashes2 fires
“Car has unintended acceleration that can only be stopped by turning off ignition key. This happens without warning. When stopped and foot on brake car accelerates to top rpm then brake goes to floor resulting in no control of car.”

Cruise control NEVER worked, a/c stopped working at 77,000 miles, window motor on both doors broke before 75,000 miles”

Air bags

22 reports7 crashes
“I was driving my car and heard a loud sound and then my airbags went off. I lost control on my steering and was able to coast the car to shoulder. The airbags deployed even though there was no collision with another car. Under further inspecting it looks as if all the bolts came loose on the drive Trane. I have no idea why the airbags went off. I did sustain an minor injury to my hand. police were called, fire trucks checked for possible fire hazards. I looked for recalls and or air bag malfuctions for this year make and model but did not find any. Had I not been in the far right lane I could have been in a serious accident. The airbags deploying scared me. Both the driver and passenger side airbags went off. I was the only one in the vehicle.”
