My wife and I both own 2007 Pontiac Grand Prix gxp. I experienced a right rear flat while driving. I pulled over and noticed the whole tire was seriously ripped. The other rear tire was bald on the inside. When this happened the vehicle only had 17000 miles on it. A month later my wife's vehicle started having the same problems at 20000 miles (inside wear on both rear tires. The dealership stated that these cars are bad about that, you need to have your tires aligned regularly. Replaced rear tires on both vehicles.

Follow-up on ODI #'s: 10191952 and10192426 repair attempt three on automatic transmission. As of midnight tonight, this makes 15 consecutive days the vehicle has been at the dealer for repair of the transmission. Dealer called today, stating vehicle is repaired. They replaced the transmission with a "re-manufactured" transmission they ordered from GM. So, I've got a brand new 2007 Grand Prix gxp with 3,200 miles on the odometer, with a used transmission from GM. Dealer insisted vehicle had been taken for several test-drives today, and it is in "like new" condition. Upon taking the car for a test drive, myself, I noticed that the gearshift was loose, and did not lock into place, as it had before, and as it was designed to do. Any slight pressure or bump in the road caused this "new"("??") transmission to shift into neutral, without control input from driver. Basically, there were no detent stops for the gear indicator, and it freely moved between drive, neutral and reverse! dealer stated they would once again attempt to repair. Dealer did not close-out the service ticket, so they are making this appear as one repair attempt, even though they have: 1. ignored initial complaint, 2. attempted to repair the original transmission, 3. failing that, they ordered a used, re-manufactured transmission from GM, which has either been installed incorrectly, or is defective from the start. Even if the vehicle can be "repaired", it now has a used, dysfunctional and dangerous transmission, and the car is seriously de-valued. I am filing a complaint with GM, and thoroughly plan on a vigorous pursuit of my rights under the Florida lemon law.

Purchased 2007 Pontiac Grand Prix gxp new, with 98 miles on odometer, in March, 2007. Bridgestone potenza tires on all four wheels as oem. Tires lose air (checked with professional tire gauge every week), down to 24 psi in all 4 tires, at same ambient temp, cold tires. When tires are cold, they run as if they are square. Bumping along, steering wheel shuddering side to side. Taken to dealer. They force-variance balanced all wheels/tires and aligned vehicle, including engine cradle. Car still had slight steering shudder, became worse over the next few hundred miles. Taken back to dealer. They state tires "out of round" but did not do anything to correct the situation except to add air, and tell me that one tire threw a balancing weight. Overall, even with proper inflation, proper alignment of all components (steering and engine cradle), including proper force-variance balancing, the tires cause the vehicle to pull violently left or right, depending on the angle or crown of the road. Also, pull so hard going over road imperfections, that steering wheel comes out of my hands. Drove several other identical vehicles with other brand (pirelli) tires, with no problem. Defective tires at all four wheels. Bridgestone potenza's. have requested that service manager replace all four tires with pirelli's (they are the only other manufacturer which makes 18" tires compatible with my gxp, which uses two separate tire sizes for front and back. The Bridgestone tires are dangerous and should be recalled or replaced.
