This summer my 2022 High Country driver side mirrors would go into whatever position they wanted. After a short time, the sound for the turn signals and the bluetooth would intermittingly stop working. In October, the dealer said it was an update issue, which they did. This update supposedly corrected the battery drain issue as well. This week, when putting in reverse, I get an alert on the center dash "check reverse lamp". The infotainment screen shows all the cameras as usual. When you put the vehicle into drive, it goes to a black infotainment screen. Android auto is connected and can listen to the radio, you just can see anything on the screen. Now, if you dont use reverse, but put it directly into drive, I do not get the check reverse lamp or the black infotainment screen. Everything operates as normal. Drive to your destination, put into reverse, get the black screen and check reverse lamp message on the center dash. For whatever reason, the act of putting it into reverse messes everything up. The dealer yesterday, looked up the battery software update again and they still dont have a fix for known issues. Has anyone seen or heard of this? Any ideas?

Any backup bulbs burnt out?

Well, I checked, driver side back up light out. I hope that fixes the black screen issue. I get the dashboard alert, but not blacking out the infotainment screen. I went down the rabbit hole of the update issues. Thank you for looking at something simple.

So, didn’t the infotainment actually tell you the backup light was out?

The dash above the steering wheel said rear light was out. The big infotainment screen went black as soon as I put it into drive. This is what threw me off. Which is why I went down the rabbit hole a upgrade issue. I have appointment monday at the dealer to fix bulb, since should be warranty. Will see if fixes issue. I never thought a bulb would be bad in 3 years, along with the floppy mirrors and other issues.

The dealer replaced the bulb this am. This obviously fixed the check reverse lamp warning on the dash. The blacked out screen going from reverse into drive is gone as well. Dealer still thinks software issue. Will see what happens. I still cannot fathom a reverse bulb would take out the infotainment screen, but what do I know.

Maybe the government agency or some nanny at GM wanted to make sure you change that bulb right away and not ignore it?

Or GM wanted you to miss out on a ticket for a light out.
