What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
As I was about to put the vehicle in park it lurched forward going over a standard curb across a sidewalk and then into the brick wall of the building. The air bag did not deploy. The car lurched about ten feet total before hitting the wall.
She weighs approximately [XXX] and was properly seated with her seatbelt fastened. The only airbag that deployed was the driver’s knee airbag. The front passenger airbag did not deploy at all.
The car went over a curb and hit a fire hydrant. The fire hydrant broke off and the car rolled over it. The car went into the street and she steered it to keep it out of traffic and stopped by using the parking brake. There were no warning lights. The airbag(s) did not deploy. There were no personal injuries.
There were no warning lights before or after the incident and the service advisor said no codes had been set. In retrospect I should have tried putting the transmission in neutral, used the emergency brake,or turned off the ignition (but a tractor trailer was about ten feet behind me).
The air bags did not deploy. The contact sustained bruises on the lower and upper back, bruises to both knees. The contact also sustained vision impairment to where he started seeing black dots and a bruised left arm. The contact was also suffering from panic attacks.
This vehicle has been in an accident with damage exceeded $5000.00 (I have a Ford Dealerships estimate to prove damage on the vehicle has not been eepaired nor reported) Again, substantial, front drivers side, hood, wheel, breakline, door and underbody damage occurred to this vehicle.
In that collision, even though I was wearing my seatbelt, my head went straight up and I hit the top of my car. My head felt crunched into my neck and shoulders, and the belt restrained me enough to pull my right shoulder back and down from having my head crunching further into the top of my car.
While preparing to back up, with the engine idling , the engine shut off without warning and I had no control of the steering and would not restart when I attempted to do so. This could have put anyone behind me at sever risk or maybe caused an accident should I have been on the highway.
