2005 Pontiac Grand Prix Engine cooling Problems

“On 1/23/12, while backing out of a parking space on a level lot, my 2005 Pontiac Grand Prix lunged forward. I immediately hit the brake. The car was in reverse not drive! I attempted to back out again and the same thing happened! The second time it lunged forward so quickly I was afraid the car would not stop, even with the brake fully applied. This second lunging incident damaged/cracked the air dam, as it was now wedged against the concrete parking space divider. At the same moment, the dashboard flashed/lit up like a christmas tree....and the engine stalled. …”

“My 2005 Pontiac Grand Prix gxp would often lose speed in curves, climbing hills, or at high rates of speed. I took it to a GM dealer and was diagnosed with transmission problems. I was quoted one price for transmission, labor, and radiator replacements, but ended up paying over $4000. Gwatney in north little rock, ar has a horrible service staff. They were not willing to work out a deal even after informing them I was quoted a different price. They threatened to charge me additional storage fees if I didn't pick up my car. I eventually paid, but I wrote in dispute of price on the receipt. …”

“The contact owns a 2005 Pontiac Grand Prix. When the window defogger is activated and the windshield wipers are engaged, the vehicle shuts down. While driving 70 MPH, the vehicle stalls and loses power. The mechanic stated that the o-ring was missing, which causes the vehicle to lose power due to lack of heat. The mechanic was unable to duplicate the failure. When the contact took her vehicle to the dealer, it was still under warranty. However, when she picked up her vehicle from the dealer, she noticed that 100 miles had been added, which put the vehicle out of warranty. The failure persists. …”
