Has anyone had an issues with their display giving pretty much every warning possible. The fan also cranks up to high and the temperature goes to 76. It’s a 2025 Z71 and has been in the shop but they can said they can not do anything unless it happens while they are in it. The dealership updated the software but it still continues to do it. I have multiple videos of it and it eventually stops after a couple minutes.

Probably a bad module corrupting the CAN bus. This happened on my 2015. All lights on, random errors, everything goes nuts. Mine was because the blind spot sensors were damaged (moisture) and they were corrupting the message traffic on the CAN bus. This caused many other modules to get com faults and set tons of errors.

I found it but looking at all the code history and noticed that the constant code that would come up with all the other crap which was random was the blind spot monitor loss of coms. Checked it out and noticed it had a cracked case and wet inside. Replaced and no problems.

Just looked at the sensors they look good but will keep that as an option. Thank you.

From afar - I’d bet a failing battery and/or loose or corroded battery terminal connectors.
