My 2020 Sierra 3500 hd has been in and out of dealership service for many electrical issues. First it was headlights quickly turning on off over and over. I had to stop driving at night for obvious safety concerns. Then radio would randomly turn on and off. Dealer worked with GMC offices to try to fix. Got it back from dealership service dept stopped for dinner. Turned truck off, locked doors. Halfway through meal waiter said ‘hey you left your blinker on…wait, now all the lights on your driver side are flashing!’ Its back in the dealer service center.
anyone else have similar problems? Hear about similar problems?
i appreciate all responses!
