What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Vehicle suddenly accelerated out of control, brake did not respond, resulting in accident. Tt
I recently bought a second car and noticed that the engine had a lump or a surge at idle and at operating speed. I thought since the car sat for a while before I bought it the problem was fuel related. I took the car to repair shop for a new fuel filter.
While backing out of garge in reverse vehicle suddenly and without warning accelerated out into street. Driver had both feet on brake pedal to get vehicle to stop. This problem had occurred on two other occasions. Vehicle was in dealer shop on one occasion, and they were unable to duplicate the problem.
Throttle is defective, causing vehicle to suddenly accelerate, consumer stated that that three collisions have occurred because of this problem. Dealer has been contacted, but was unable to locate source of problem. Please provide further details.
Valve cover gasket leaks, causing oil fumes to enter into passenger compartment.
Head gasket leaking oil, due to high oil pressure, could result in a fire. Tt
Warning light on dash (srs) would light up and stayed lid a few minutes. Currently on permanently. Dealer sold an extended warranty, but insists consumer use old parts.
