2020 2500HD WT 2k Update - Issues

[CT Chevy Connoisseur]

So far:

Stereo cuts out randomly - took to dealer they ran some diagnostic stuff and an update - did not work going back

Door molding near handles has a gap that won't close up - they ordered replacement one but annoying just the same

 

Finally a question:  I added rock lights to my upfitter switch and aux battery, now I'm getting a low battery warning which makes no sense to me.  Why would there be any battery draw if the upfitter switch is off?  Lights won't come on without it being depressed so not sure why there would be any drain at all.

My radio does the same thing. It is a service bulletin for a lot of GM models with no fix yet. Dealer says when a fix is found they will send a flash drive to update the system or down load over the On Star.  2 months and still waiting.
