Mine did it when it was less than a month old. Came back on the same day but went out again. Dealer performed an update to the radio which took hours but has worked fine ever since. If it did it once but came back on you're gonna be in the dealer getting it updated sooner than later. But my most fun gremlin was when the hood latch sensor (didn't even know I had till then) went out. Truck also threw a code and put the SES light on because of this sensor. Which meant the remote start wouldn't work. Most fun part was after it was parked and locked the alarm kept going off and notified OnStar that the truck was being stolen. LOL

I live on top of a mountain in the northern Appalachians in PA. It does so little it is not even worth talking about in normal mode. Either way on saving brakes or wearing on the driveline. It's just there.
