I have a 2021 GMC Seirra 2500 HD and love it. currently have 36,498 miles on it. The only thing I don't like is it has blind spots around the mirrors both left and right. And I do not have the sensors to alert me. But recently I was towing my 33 ft travel trailer and suddenly the screen where the radio/climate controls and several other functions are located, went blank. Truck was still running thank goodness, but it all went blank for about 10 seconds. Then just as suddenly came back on. Haven't had it scanned for error codes but none of the warning lights came on, just went blank. Anyone else seen this issue. Prob just a computer glitch or maybe was doing an update?
