“I was driving in the rain and hit a puddle the was an 1 !/2 in deep and water got up into my engine and ruined it. I have to get my engine replaced and had to go through the insurance company that cost me 1000.00 deductible. This is the 2nd time that I've heard of this happening in the last 2 months. I feel that this is a GM defect. The water was not that deep.”

“I purchased my 2006 Pontiac G6 in august 2008 with 36,000 miles .less than a year later, the AC compressor on this three year old vehicle seized. The serpentine belt snapped while I was at a red light and everything failed, the power steering, battery, everything. My mechanic says it will cost $1700 to repair. There is no way a car that new should have such a failure. In addition to that, the factory installed cd player stopped working for no reason. The arm on the passenger side seat stopped working. …”

“2006 Pontiac G6 v6 stalling while in drive and park. There were no events leading up to this and has occurred six times. While driving at low speeds or in park, the car will suddenly turn off and the check engine light will illuminate. The brake and steering will also lock up. Upon turning the car off and placing it in park it will restart, I have placed the car in the shop two times to have this fixed. Last time (may 18) was to tape engine wires and clean the fuel injector, which they said would fix it. This repair cost me $500. …”
