I have the exact same issues, triple unlock, heat/vent seats not working and memory seat not working. I did have codes for something about rear antenna and a couple high & low voltage codes but none of those relate anything to BCM or Airbag sensor, so I'm lost on what to do next. Fuses are good and battery is good.

Hi GoldGhost,
IF BCM was updated in the way I mentioned in previous posts then I cannot provide more insight.
What I would suggest is to double-check if the Update procedure was executed correctly - not sure if you were present the last time and can confirm that they did it exactly the same way (maybe they sipped some steps or executed Update not on BCM level but on general level - I have no idea). Maybe visit another dealer? Or better someone proficient with GM electronics like I did (my guy works in the GM factory in Poland - and gets his knowledge from there).
I hope you will get that figured out.

BR,
Jarek
