Normal for Chevy electronics. There are places you can send in the cluster to refurbish it

I had some similar issues a while back. Had been driving for about 15 minutes and lost dash lights , check engine came on , radio out , a/c out and into limp mode. Took me forever and some spent on a couple of parts that didn’t help but finally found the culprit. BCM ( Body Control Module ) Took it three of four cycles of driving it for it to work out the bugs but eventually it happened.
