2019 Yukon Electronics Went Haywire, Advice?

The solution was a master reset if some kind and it’s functioning properly now. Hopefully it was a one time thing. I’ll report back if it happens again and update

Thanks for reporting back.

If it happens again, seriously, try disconnecting the negative and positive battery cables and touch them together. It will kill and bleed any residual voltage from the system and has been known to solve issues like you were describing.

My neighbors Acadia had the dash go wonky on them and the blind spot indicators were on constantly. When they did this, it reset everything and they were back in business.
