The car wouldn't start after you shut it off. That happened 4 times. Then it started stalling going down the road. No warning light just shut off. We changed the throttle body and then the temp sensor. It was still happening. Then we took it to Midas. The mechanic accidentally leaned on the fuse box under the hood and the car shut off. He moved it again and it turned back on! They changed it out with the factory part (don't get the aftermarket part) I have had no problems since. It's been about 3 months. This should be a recall! This problem is posted all over the internet with no known fixes! We just happened to get lucky that he leaned on the fuse box! By the way, I even had called Chevy and they didn't have a clue what the solution to the problem was. I will be calling them tomorrow.
