2007 grand prix gxp brake issue by ktemmen

For those considering the purchase of a gxp or any other pontiac sedan, Beware!! I just had the misfortune of taking in the wifes car for what i assumed was warranty work. 21.000 miles and both front and rear brakes were shot, rear pads nearly to the rotors and in the case of the fronts, right pad completely gone. 25 years of doing business with this dealership (Waldecker Pontiac/ Buick) and the best they could do for me was tell me that it was due to my wifes driving habits but did me a favor by only charging me for repairs to the rears, they covered the front. You have got to be kidding me. I will spare you the conversations that took place between myself and the dealership personnel but they were willing to lose a long time valued customet over the $200.00 repair bill. Very funny that we had no issues with Sunbirds, or Grand am's. Bottom line is that GM is fitting this vehicle with poor quality parts. End of Story. Still cannot believe any dealership good or bad would have the gall to blame the cutomer for their short comings. Never again will we own a GM product.

Grand Prix GXP bad brake rotor design by tremicklaw

After being told my second set of rotors on the front of my 2007 GXP were shot with less than 40,000 miles, I bought after market rotors from a brake specialist in California. Wear with new brake rotors and ceramic pads is even and no sign of grooving on the rotors, which appeared almost immediately with the GM product. Here is my theory: The problem is the absence of enough bevel on the drilled vents on the GM rotors. The steepness of the drilling without the bevel causes the bad to be damaged, which in turn causes scoring along the rotor. There was a remarkable difference in the slope of the aftermarket brakes versus the GM product. Almost no chamferring on the GM rotor. Which begs the question, are they just in the rotor selling business these days? Why else would they design a product that is going to chew into the brake pads creating an uneven surface that will score the rotor?

2005 Pontiac Grand Prix GTP by chicanutella

On October 20, 2007, I bought a 2005 Pontiac Grand Prix in which within three weeks of purchasing the car I had to take it back to the dealership three times. The steering wheel was shaking when slow down, the front end of the car felt like it was going to come apart and since I didn't know anything about it, they told me it was fixed the first time. I took a trip to a different state and on my way back the car wouldn't go over 50mph, so I called the dealership and as I figured, they couldn't do much about it since the car wasn't there (duh). So, I called to get the car towed and the lady told me there was a GM near where I was at, so she guided me to get there in which the people at that Dealership was very helpful. It was something with the computer that prevented the car to go over 50mph. In regards to the shaking issue, the guy told me that i had to get my rotors/brakes replaced. I took it back to the dealership from where I bought it and a 3rd time it was fixed in which they were looking at me like it was my fault... I never went back...Now I'm having an issue that the right front tire is making a noise, I took the car to two different mechanics, and apparently i'm crazy because they say they can't feel anything. I hear it making a clap clap clap noise (i know silly me trying to describe noise) and when driving and also when i steer i feel like a detaching noise... I'm scare that the car is going to fall apart one day...
 
My question: I want to know if grand prix's have a rotors/brakes/abs system factory defect??? (I called Pontiac and of course, they will not say anything in particular)...

I have a 2006 gxp. Had front pads/rotors replaced at 33k and had checked today at 56k. They tell me both sets need changed. I said bs and asked how much to just change all 4 pads. Total: about $550; just for pads!!!!!!
 
Can you tell me the name of the company in California you got aftermarket rotors/pads and contact info. Also, if you dont mind, what it cost you.
 
Thanks.

fyi. I'm not the one who purchased rotors or pads in Cal. I have a 92 GTP that I can not make a "panic stop" with.

2004 GP GT ABS brakes engaging when slowing down by ElPaco
Dec 10, 2008 (6:14 am)

I have a 2004 GP GT and recently it started to engage the ABS brakes everytime i come to a slow speed. Sometimes I barely get it to stop because brakes won't stop sputtering and slipping. Every once in awhile the "ABS Brake Enaged" light comes on when stopping. I was wondering if this is a electrical problem or something else?
