Infotainment Doesn't Work

[Michael A]

I have a 2020 Yukon that has about 2100 miles. My gages do not work. When I start my Yukon, I see the engine warning light illuminate, but the gages do nothing. The Infotainment screen does turn on, but I do not see the GMC splash(startup) screen. The backup camera does work. Bluetooth, radio, speedometer, odometer, fuel, oil, battery gages, and turn signal indicator do not work. I called the dealership at 4PM to make an appointment and they told me that is a problem they haven't heard of before. I'm not sure I believe them. I tried resetting the fuses that pertain to the infotainment system. I'm not sure if those were the all of the infotainment fuses? Any help would be appreciated.

It’s a brand new vehicle with very few miles. The problem could be as simple as a loose ground connection or it could require replacement of a major component. I wouldn’t touch anything on a vehicle as new as yours. I would leave it in the hands of the dealer and let the warranty work it’s magic.
