All fuel lines have been replaced due to corrosion, vehicle continued to leak fuel after the repairs. Please provide any further information.
Acclerator stuck.
The lights on this model, and I have seen many, have a problem with the lens. As they aged, they fade and become very white and weathered. In the daytime it is difficult to see the brake lights for the persons behind the car. I noticed this myself behind one. When I went for inspection, I was asked if the lights were out, then it was realized that they do work. At night they are more visable. Pontiac shoud replace the lenses on these cars. The le and se models do not have this problem. They look fine, and brite. Thank you for your time.
Suspect related campaign for ABS hydralic valve block (intermittent pull is wheel lockout).
While on a two way street, brakes got hard and car would not stop. Consumer had to keep pumping on brakes until it started to slow down.*ak the ABS failed teice and the consumer feels unsafe to drive the vehcile.
The ABS brake system has failed intermittently since the car was new. It was never fixed and was hard to duplicate. The brake pedal will be locked out under a panic stop but the ABS fails to kick in and the car is essentially brakeless. Others have undoubtedly died or suffered serious injury because when this occurs the car is a missle.
