This started about 3 months after I got the truck and has been doing it since. On three separate occasions, truck engine shut off after stopping then turning right on city and neighborhood streets. First time I pulled out on a road where the speed limit is 55 so I was lucky no one was behind me when the engine cut out. On the fourth occasion, truck shut off after backing up from parking spot and pushing on gas to go forward. No check engine lights, no noises or vibrations to tell me truck is going to shut off. I have to look at dash to see if it has gone black. Radio still works, and I'm able to steer off to side off the road because it's still in motion from after the turn. I can put gear in park position, turn key to off, then start the truck like normal. Have gone to mechanic and dealership and they can't get it to duplicate. Chevrolet has been notified but has said they cannot help if dealership can't find the problem. Steering wheel also starting to get stuck in turn position when turning right. Right after the turn it feels like it catches in something and I have to force the wheel back to center. Starting to happen almost daily, but not for dealership. I feel driving the truck is a safety hazard for not only me but others on the road.
