I posted before thinking I was going to get help but nope. Sara emailed me back and said to contact customer care. Was on the phone with them for over an hour to be transferred everywhere only to be told to take it to the dealer which I already had. The dealer updated my vehicle, and after that I have zero connectivity through OnStar and my dash and radio screen keep glitching and turning off completely as I am driving. They opened up a case, and supposedly connected me to a technical support which then tried to run a diagnostic, but it failed as there are no lights on the OnStar buttons. I have been without my vehicle for over a month now and the dealer seems to be emailing GM to no avail. This is my fifth GM vehicle and I have three currently sitting in my driveway. I am highly disappointed. as my husband’s Silverado was a lemon.
