I was driving down the road when the car shut down everything I was scared because I had traffic right behind me going 45mph and then they car would not run again. I was right in the middle of an inter section at hall road and 59 it was the scariest thing that has happened to me. I bought this vehicle as a used auto and I'm not sure if the emmission system ever got changed and this happened once before and the dealer said not to drive with my house keys attached. I had to get the auto towed home.

My car will shut off when I am either turning or slowing down without any warning, I put the car in neutral, turn the key off then on again and it starts like nothing happened. The engine doesn't show any warning lights it just shuts off. This has happened now about 6 times. I don't have the money to take it to the dealer, but if I am given an idea of what to look for I can take it to my mechanic who is very qualified and did replace a sensor that went bad. Please help

I got home one evening and when I turned the ignition key to shut the truck off the engine continued to run. I was concerned; as I could not leave the vehicle running all night; at that point I tried to engage the key again and the vehicle was still running . I became concerned and started to fiddle with the knobs and was surprised when after turning the highlight switch the engine shut off. The next morning I hestitately attempted to start the vehicle and when I was successful I headed straight to the gmc dealer. The dealer said that it was a wiring problem and the ignition wiring had to be redone; (the cost was $1600.00) I started a dialog with gm and they engaged me with several conversations; which LED me to believe that they would pick up the cost; as electrical components were not part of any scheduled maintenance that I as a owner would be responsible for. When I made a request for reimbursement I was told that because of the mileage there was nothing they could (or would do). I could see if it were related to an oil change. Brakes,filters,etc. But as a owner this item is outside of my area of responsibility. Gm should stand behind their products and make me and others whole. Ps.

The rear driver door popped open and won't close. The fan clutch failed 2 weeks after I purchased the vehicle. I thought the transmission went out because it was winding really high and not driving normally. Also the rear passenger doors on both sides have malfunctioned. The window on the passenger rear went out. I have not corrected the failures as of now.
