At random, the key does not come out of the ignition. It happens for no specific reason, the steering wheel is straight when I shut of the car, it is not parked on a hill. The key just won't come out. I took it to a chevy dealer, but they could not get the key to not come out when they had the car, which was an 1 1/2 hours. I was charged $130 even though they didn't fix anything. They wanted me to leave the vehicle with them for a day, charge me $400, to see if they could fix it.
