“Was in a accident 2/16 speed limit 40 driving on city street. Car in front of me stopped in middle of the rd and started backing up tried to avoid collision and still had impact. The airbags did not deploy and the car engine seemed to accelerate instead of slow down. I had this happen one time before while breaking but then it switched back and drove normal called dealership and they said no recalls. My car was a total loss front impact no airbags deployed”
NHTSA complaint #11189957, filed 2019-03, 72,000 miles“Was driving the vehicle at a fairly lower speed. (35 MPH). Was utilizing the cruise control, moved my right leg, and due to the positioning of the ignition, my leg bumped the keys slightly, which caused the key to turn into the position where the vehicle was no longer running. Upon noticing that the engine had stopped running, was still successfully able to place the car into neutral and restart the vehicle without causing an accident- however, had I been driving at a higher rate of speed, this could have been catastrophic.”
