I'm having the same issues as others, dead battery, key stuck in ignition, lights flickering, radio off and on, can't use a/c, car dead anywhere from 15 minutes to several hours. Most disturbing to me is being unable to put the car in Neutral to move it away from gas pumps or out of the road for safety. When this car is dead it's a death trap. I'm contacting the dealership next week for appointment and I'm hoping it's only the battery cables. I think GM should issue a recall before a life is lost over some cables!
