What owners report

Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.

As time passed, the light came on more & more frequently. The engine then began to idle high and would go into a "super idle" where I would have to nearly stand on the brake pedal to stop the forward motion at a stop. Ow the "service engine soon" light is coming on constantly and the vehicle stalls constantly.

Engine and cooling · 2001-10-16 · NHTSA complaint #753207
Most disturbing is gm refusal to admit seat belt retractor problem and fix it. This is safety equipment which should last the life of the car, was replaced once under warranty and has failed again. Why should I have to pay $350 + labour cost when it is so obviously a defective part?
