Had new front brake pads and rotors put on car with under 16,000 miles on it. Sometimes brakes vibrate and make noise. Called dealer and was told brakes were not covered under warranty because it's normal wear and tear unless there was a mechanical problem.

While braking vehicle pulsated. Dealership repaired all four of the brake rotors/brake lines/calipers. However, consumer was still having the same problems.

I have had to replace the front rotors on my car 2 times and don't even have 30000 miles on it. Yet, I bought it brand new with bad rotors, and now it did it again, and my mechanic has told me he has had several vehicles with the same issue. I took it to the dealer, and they replaced the rotors. Very nosey brakes, and when sitting still it was almost like a light vibrating.

2002 Pontiac grandam GT-1 has continuous grinding, rubbing, and popping sounds from the front steering. Also has uncontroled power steering where the car could go off the road. Dealerships can or will not try to find these serious defects, they say that it is the tires that is causing these defects.this is the second new GT-1 within the past three years with the same defects that I have owned.
