Brakeline connection under vehicle (in front of where driver sits) could become cracked or broken if knocked by road debris, or bumps in the road. I noticed this on my 2008 Grand Prix gxp, so not sure if this model sits lower to the ground than other Grand Prix models. Watching reservoir fluid level to determine how much is lost over a month. I discovered after noticing a burnt fluid smell in the cabin after 16 Mar 2012. Particularly strong after hard brake situation I was told by local dealer that there was no warrenty on this vehicle, and that the parts may not be available anymore.

Under hard high speed braking the front brakes shudder badly causing a severe front end shimmy due to warped rotors making stopping difficult. If pressure on pedal is not released this could cause loss of control and a crash. It is worse if going downhill. This is a very common issue on GM cars build in the last 8 years. There are posts all over the internet about this. The problem is with poorly made brake rotors that warp at under 15,000 miles of normal use. I have had the same issue with my wife's 2003 Impala. These cars should be recalled and the rotors replaced with parts of adequate quality. If you can get the issue addressed under warranty, the dealer will only either turn the defective rotors or replace them with the same oem junk. The only fix I have found it to replace them with aftermarket rotors and pads.

2008 Grand Prix gxp front wheel cracked, losing air with 24K miles. The week before it was brake pads and rotors. Total out of pocket expenses $1,200 in two weeks. I find this absolutely unacceptable for a car with bumper to bumper coverage. Just exactly what do they cover? last I checked my wheels were between my bumpers, and if GM can't build a car road worthy of a Michigan winter they should not be allowed to sell them here. This would be alot easier to swallow if it were a used car, but new with 24K miles is absurd!

The contact owns a 2008 Pontiac Grand Prix. While driving 55 mph after purchasing the vehicle, the paint began peeling. The dealer stated that the failure was caused by exposure to acid rain and they offered to re-paint the vehicle. The contact also felt a hard vibration when depressing the brake pedal and accelerating to 55-65 mph. The failure mileage was 400 and current mileage was 800.
