Hummer EV is broken, no one can figure out why
I have been experiencing the same exact issue for the past several months. No resolution provided by, GMC doesn't care about fixing the issue they just don't want to deal with it. I will never buy a GMC again.
After multiple dealership visits, they noticed that the Supercruize wasn’t working. They ended up changing a telecommunication module and that seems to have done the trick. App works now consistently and Supercruise works as well. The Wi-Fi hotspot feature OnStar customer support was able to help “reset” to start working.
