I have a 2023 Canyon AT4 that has heads up display that stops working intermittently. The dealer has replaced the HUD, the radio/entertainment center and the cable running between them. I have made certain the fuses are seated. I & the dealer at a loss. Has anyone else experienced this problem? Any suggestions for solving this problem would be appreciated!

Yup, same thing - HUD mignt work/not work on any given day/start up. It's been at the dealer a few times, with no luck. They had opened up a ticket with GM TAC, and even they did not have a clue (per the dealer). Dealer now has a replacement HUD display on order, so will see . . .

Letting the BCM completely power cycle fixes it every single time for me

How do you accomplish that?
