I just had this happen two nights ago and was able to get them to reset to just a CEL after a bit of messing around. Dealer pulled codes and opened a case now waiting for a new update to be issued from GM. I just had the brake recall done and module updated of course their is no ETA on the update...7,200 miles Sent from my iPhone using Tapatalk
Man I really wish somebody would come out with something for the GMC’s....might jus have to make something a little custom down the road if it doesn’t happen. Sent from my iPhone using Tapatalk
My passenger side tow mirror does this as well - when I pull out of my heated garage drive to work in the morning park hit the fold it either doesn’t go or only goes partial. I have to cycle it a time or two for it to fold all the way in. We have similar temps in the frequently below 0 and then in the low single digits or teens.
