c8 instrument cluster goes blank
2023 C8 instrument cluster went blank on 2 occasions. Each time the car sat outside in 85 degrees + for over an hour. When starting all systems operational except for the instrument cluster, completely dark. tried everything I could, no results. The only way that corrected the problem was when the vehicle cooled down in my garage and all systems were go. Haven not had the problem since cooler weather arrived. Finally took to the dealer and they are at a loss as to the sporadic issue. They reprogrammed the entire computer system, so we'll see if the problem re-occurs.

My 2022 did it once right after I started it it was on than blank. It takes 15 min for the BCM to shut down so it can do a cold boot up. I'm in the Central Valley in Ca. My car has been outside parked in 110 deg days without issue. I don't think it's a heat issue. More a boot up hiccup.
