2018 GMC Sierra - Stabilitrak/Trailer Brake/Cruise Control Out

[2018 GMC Sierra SLT]

Upon start-up I get warning messages about Trailer Brake System and Stabilitrak.  After start-up I get ABS and Stability control dash warning lights.  While my cruise indicates it is on, nothing happens when I try to set the cruise speed (and green cruise indicator does not light up either).  Any help would be much appreciated as the dealer is backed up with holiday work.

I have not run the codes, but plan to do so today.
