This is an ongoing issue with the battery draining and not being able to start the engine. Happened on June 9, 10, 12, 13, 15, 2016 and it seems the dealer's service dept. cannot find the problem. my truck is only six months old. Never had a new vehicle do this to me before, I am considering returning the truck and getting a refund. I already informed my bank about this issue. First and last time Chevy owner! I will never buy a Chevy again!!!!!!!!!!!!
