Complete brake failure occurred at a high-volume intersection at logan ave., and rt.20 in belvedere il. While approaching intersection on a yellow light, with no one in front of me, I applied the brakes, heard a popping sound and the brake pedal went all the way down to the floor board. I had enough room to apply the emergency brakes, and came to a complete stop before entering the intersection. I had my sister and 92 year old aunt in the car. Car was towed to wolf pontiac in belvedere, il, mechanic told me that the 'steel' brake line had rusted out, and burst. We had all the brake lines replaced for approx $900. We could have had serious injury/death had we entered the intersection. This is a serious example of an engineering defect! We live in the salt belt, and any design that would lead to a rust-out situation on a critical part of the braking system is inexcusable. It is probably cheaper than putting in brake lines that would be rust resistant, but I guess profit is more important that the safety of its passengers. We were very lucky! I called gm, and of course they were apologetic, but the same thing is going to happen to other drivers of their technology. The owner of the car, is my aunt, who was a passenger

The ABS systems engages while driving and not pressing the brake pedal. You can hear the ABS systems trying to engage and then the ABS and trac off lights come on in the dash. This is deactivating my ABS system. I have had a faulty ABS sensor replaced and it fixed the problem for about three months. It has now started up again. I have looked at numerous message boards to find a fix for the problem and was extremely concerned to see that thousands of grand prix owners are having similar issues and gm is doing nothing to fix it... Except charge $1300 and still not fix the problem.

Tl* the contact owns a 1999 pontiac grand prix. The contact was driving approximately 25 MPH when the brake pedal slowly traveled to the floor upon engagement, with the illumination of the brake warning indicator. When the brake pedal was applied, the vehicle failed to reduce speed after numerous attempts. Immediately, the emergency brake was engaged to stop the vehicle. The contact resumed operation. The vehicle was inspected and the master cylinder reservoir was empty. The vehicle was taken to an independent mechanic where they replaced the front and rear brake lines as a result of rust. The contact was in the process of notifying the manufacturer of the brake defect. The approximate failure mileage was 64,000.

The contact pulled into her driveway and noticed that she was no longer able to brake.

The same day, the fuel pump and fuel filter malfunctioned, which the contact noticed when the vehicle was shut off. The contact had the failures replaced, but the vehicle still would not remain on. She had not taken the vehicle to the dealer or spoken with the manufacturer. The current mileage was approximately 135,700 and failure mileage was 135,533.

The following occurred on a 1999 grand prix that has 52,300 +/- miles on it, located in southeastern pa and not garaged. I went to start my car after a meeting and the brake pedal went to the floor. Subsequent investigation in the meeting location parking lot showed that brake fluid was pumping out of the brake line system. I had the car flat-bed towed to the local pontiac dealer. A brake line had rusted through in the engine area. The other brake lines up under the chassis were also rusted. The pontiac dealer is replacing all of the brake lines with new lines that have to be bent to shape. Only two small lines were available pre-bent from general motors.

We have a 1999 pontiac grand prix with a little over 100,000 miles on it. In the past month, it became more and more difficult to remove the key from the ignition. Finally, we were unable to remove the key at all. We had the car checked out by a local pontiac dealer and we were told that the car could no longer recognize when the car was in park. We were told that the complete floor shifter would need to be replaced because the unit parts could not be individually fixed. We also were told that the problem could be bypassed, but that it was really a safety issue. I work with someone who also owns a 1999 pontiac grand prix with a little over 100,000 miles, and they had the same problem. My dealer told me that they are seeing a lot of this problem on the 1999 vehicles with the same mileage. It cost of $377.16 to repair this part.

After driving in the rain brakes will not work effectively for 2-3 seconds after application. Has occurred several times since new. Was told by dealer that this was normal. It is a very dangerous situation to be exiting an expressway after a 10 mile drive and have this occur in light rain.

This complaint is not necessarily concerning the absolute failure of a component, but rather the repeated need to replace, what I consider to be, a critical safety related component. First of all the need to replace the front rotors prior to taking delivery of the vehicle in march '99, and then the need to replace the rear rotors in october '00, with a little over 15,000 miles on the vehicle. No explanation was given by pontiac. My correspondence to pontiac in response to a customer service survey, yielded merely a telephone message that confirmed basically what I had told them regarding the two times rotors were replaced, implying to me that "I can expect to replace rotors on the vehicle every 15,000 miles. To me that indicates that pontiac are esentially unwilling to admit to a quality, and more importantly, critical safety problem in a component of their product.
