“I purchased a 2003 Pontiac Grand Prix se with a v-6 and I get water coming in the passenger side every time it rains. Also the transmission shifts hard occasionally when going from first to second gear. I was told to fix the leak would be around $300 and the transmission problem.... I may as well buy another car for that price....”

Then at 68000 miles the transmission was slipping and had to be rebuilt at a cost of $3000.00 (several part along with torque converter). In each case the mechanics stated that this is a known problem with the vehicles and that these parts were inferior. …”
