I had it happen months ago, had it happen yesterday as well. Have also had issues with the truck consistently starting, and the steering wheel whipped out of my hands twice while driving in reverse. I've had the truck shut off, flashes multiple codes; service stabilitrac, service theft deterrent system, roll window down and back up, trailer brake system etc....my truck in particular is a wreck. I'll trade it in within a month hopefully . There are some other threads on here to search: steering wheel whipped out hand, trouble starting consistently, etc. Some members have had issues while driving, it's a lawsuit waiting to happen. I hope it doesn't take someone dying for the greedy, lazy assholes at GM to do something about it.
