I am experiencing repeated problems with the brake rotors. When traveling at highway speeds (above 50 mph), if the brakes are applied, the car, including the tires and steering wheel, vibrates/shakes back and forth. Sometimes it shakes so much that it feels like control of the car is compromised. Several auto mechanics have told me that the problem is definitely that the brake rotors wear out. The brake rotors have already been replaced twice (the first time by a Pontiac dealership), and now need to be replaced a third time, even though they were replaced less than a year ago.

On the day I bought the car I took my family out to dinner. We returned to the car after finishing our dinner and the car would not start. We tried for almost 1/2 hour then called for the road side assistance. They came and picked up the car and we went to the dealership. They told me it was a computer component and the car would be ready the following day. After arguing on how we would get home since the dealership was now closed as was the rental car place they finally agreed to let a porter take us home, the porter had a small car that would only hold 4 people and there were 6 of us. Theis meant 2 trips and we lived nearly 30 minutes away. Long story short a very dissapointing first day with my new vehicle. Within a few months my drivers window would not work or worked when it felt like it. I took it in and they replaced the window regulator. Problem solved, then a few months later the window would not work again with the regulator. It worked for almost 2 years then it started up once again and still being under warrenty (gmpp) they took the car in to look at. I left it for a day and returned to be told the window was fine and yes it was working. A few more months go by and the window is not working so I go in again and again it works for them not me. This goes on with me taking the car in and the button works when the tec looks at it then after I leave it does not. I was in town 05/03/2004 and the window went part way down and stuck, I quickly went to rally Chevrolet, where all the repair services have been done, and showed them the window would not go up or down. I thought finally this will be taken care of but no I was told taht the warrenty was out and I was over mileage and the cost for the front and rear window would be nearly $1,000. I told the service manager that the problem existed before the warrenty ran out and I felt that they should honor that and not charge me.

I have a 2000 Grand Am. My gas gauge does not work properly. Now, car is stalling and mechanic says it is the fuel pump. Right front window doesn't work. My fans do not work properly and my car overheats constantly. I had 3 sensors bad in my car and had them replaced. Rotors, brake pads and bearings have been replaced constantly.

I have been hearing a rubbing noise from front end (left?) for 2 yrs. Now. No -one can find out why.my low track light has been going on a lot lately too.in researching this on the web, I've found a lot of people with the same complaint. My question is, "why hasn't something been done about it?" it's obviously a manufacturers defect. Thank you

While driving and attempting to step on brake pedal to stop or to reduce speed, vehicle will not stop. Instead, will be involved in extended stopping distance. Dealer had repaired brakes twice. Dealer has also replaced the rotors twice, turned them once. The brake system has had to be fixed 3 times.
