I'm posting this because after doing lots of research, I couldn't find a solution.
2023 Yukon SLT Duramax
Driving down the road and every warning light and message came up on my dash. Showed no battery power and no fuel. Speakers went out (which included the seatbelt noise and blinker). After a few minutes it would all go back to normal. Then a few minutes later, do the same thing. Replaced the battery and it was good for about half a day. Replaced key fob battery as well. Finally had time to bring it to the dealership and they claim it is the amp. I will be getting it back tomorrow and hope that was the issue. I am thinking it might have been faulty from day one. Speakers have gone out many times but come back on, I thought that was more of a system issue and an update would fix it. Obviously not since it has been 2 years.
This is an FYI. Unless someone else has had this issue and knows the deal.
