2003 Pontiac Grand Am Owner Comments

problem #3

Grand Am 6-cyl

  • Automatic transmission
  • 53,512 miles


The contact owns a 2003 Pontiac Grand Am. The contact stated that the rotors on the vehicle at the time of purchase were completely worn. The dealer replaced the rotors, but would not replace the brake pads or the bearing. The hub bearing on the driver side needed to be replaced. While driving 50 mph, the fuel pump failed and was replaced by the dealer. The fuel filter was the initial cause of the fuel pump failure, but it was not replaced. The current mileage was approximately 57,000 and failure mileage was 53,512.

This is not a true "failure", per SE, but a complaint about a manufacturing defect/flaw/practice. I own a 2003 Pontiac Grand Am GT1, (purchased 8/02) which was recently serviced at 40,000 miles. At approximately 18,000 miles, during 4/04, I had to replace the front brake rotors for excessive wear and scoring. The dealership claimed that the wear was due to the use of road salt that winter. The front rotors hadn't been turned, or previously serviced. At the recent 40,000 mile checkup, I was informed that I would again need to replace the front rotors. As with the 20,000 mile checkup, the rotors had not been turned, or otherwise serviced, but were worn to the point of needing to be replaced. The large majority (90+%) of my driving is highway, which "should" be a bit easier on the brakes than city, or stop-and-go driving. At each instance I invoked the Pontiac customer service center, who were only minimally helpful. My concern is that if the front brake rotors need to be replaced every 20,000 or so miles, and is not documented anywhere in Pontiac literature, would this not constitute a documented premature failure for a safety system ? I have also noticed that this issue has been reported by other consumers, noting similar symptoms, so I'm less inclined to believe that I have experienced an isolated event. In each instance, there were no warning signs of brake wear (no noises, pedal fade, wear sensor squeal, loss of braking power, etc.) there also has been no "incidents", or accidents as a result.

Grand Am 6-cyl

  • Automatic transmission
  • 28,158 miles
(event leading) on or about 09-29-2003 I took my Grand Am into hanigan Chevrolet in Ontario, Oregon to have a brake problem fixed, the unit had 15212 miles on it, as to the unit was vibrating violently when braking. (diagnosis was) they advised me the rotors on the unit front were warped, stated the rotors were to light to handle the heat and pressure, also stated warranty would not cover them.(even though they were not worn out but were damaged due to poor construction. I paid to have it repaired. Here on the 6-28-2004 I noticed the same problem again when returning from a vacation trip, mileage now is 28158. It is going in again for analysis to the same dealer. Same failure happens approx. Every 13000 to 15000 miles....recall is needed.
