Tl* - the contact stated that while driving the 2003 pontiac grand prix on a sunny day at 35 MPH a deer ran out in front of the vehicle he swerved in order not to hit the deer and ran into a tree. The air bag deployed, the car caught on fire and was consumed by the fire. He had a hard time getting out the driver's side door, it would not open. He had to crawl out through the back window. The failure mileage was 87000 miles.

There were several problems with my car beginning with rear defrost not working. The air would only work on high. Then as I was driving home one night I turned the fan to the air/heat off and my headlights went out nearly causing me to run off the road. Then at some point my car would not start and I would have to keep trying. Then it would not start at all. At first I was told it was the starter so I had that replaced, only to find out it was not the starter.
