What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Front end collision at 42 mph that caused heavy front end damage and the air bag failed to deploy. My vehicle was in motion when the small pickup in front stopped short causing impact.
The air bags failed to deploy. The contact and the passenger sustained injuries that required medical attention. The vehicle was destroyed. A police report was filed. The manufacturer was not notified of the failure. The approximate failure mileage was 48,000.
The air bags failed to deploy. A police report was filed and there were no injuries reported. The vehicle was towed to a dealer but was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 71,000. Updated 2/24/15 updated 03/02/15
The contact stated that while reversing out of the driveway, the brakes failed and the pedal sank into the floor. The contact mentioned that the vehicle rolled away in reverse and crashed into a fence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure.
The contact stated while driving approximately 40 mph, the brakes failed to stop the vehicle and the brake lights illuminated. The failure recurred multiple times. The vehicle has not been repaired. The manufacturer was not notified. The approximate failure mileage was 150,000.
In october of 2008, after being parked for approximately twenty minutes, the vehicle rolled backwards into a parked vehicle. There was no prior warning of brake failure and no injuries. Three weeks ago, the vehicle disappeared after being parked for an hour.
The contact stated that while driving at an undisclosed speed, the vehicle stalled. The power steering was inoperable. In addition, the contact stated that the message that the key was not detected was displayed.
The abs & traction control indicators come up on the screen along with check as I'm driving. When this happens my brakes make a weird sound like a sprung spring and the brakes feel like they're gone but they're not. It's scary be sure I feel I may not be able to stop which to me is a safety hazard.
