What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that the vehicle suddenly loss power and stalled. The contact stated another vehicle crashed into the rear of the vehicle and the airbags did not deploy. A police report was filed. The contact suffered minor injuries and was hospitalized.
Car shaking and vibrating low oil pressure even when I got a oil change. After oil change car wouldn't go no more than 16 miles per hour. Car will not crank if it's 47 degrees or lower temperature. In motion in city street and highway
The airbag light came on. I was told the airbag will now only work if the steering wheel is straight. If it is turned and I get hit, the airbag will not deploy.
All the lights on my panel malfunctioning my fuel gauge is malfunctioning the airbag light stays on check engine light check tire pressure check oil all the lights stay on and I can't reset the panel I'm also having an issue with the car stopping when I put my foot on the brake it turns off
The contact stated that oil was leaking unto the exhaust manifold causing white smoke to emit out of the engine compartment. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 166,000.
Started up my car and the air bag light went on and won't go off. Also having problems with electrical lights in the dash. Part of the lights for the speedometer/air-conditioner buttons are only 1/2 working and part of the lights on the radio don't light up either.
Trying to make hard turn either left or right mostly while parking the power steering locks or gets really tight. Put power steering fluid in. Does nothing at all. What can I do. Looking at other post...obviously nothing.
When the vehicle stalled it would not restart and smoke started was coming from the engine. The vehicle was towed to a dealer who was unable to diagnose the failure due to the sensors melting. The vehicle has been repaired. The failure mileage was 63,635.
