my GMC app not working after OnStar activated and GMC.com says OnStar no active in my account??
Looks like I'm also having a similar issue. Purchased a 2018 Yukon XL Denali, pressed the button, message said that the service wasn't active so I talked to an advisor and activated my account. She said she was sending a refresh signal to update my unit, and that it would take up to 48 hours to completely activate. It's been about a week and pressing the OnStar button still tells me I don't have an active account, I can't access the my GMC app as far as it talking to the vehicle, or using any of the features BUT I had an additional key made today and got an email alerting me of possible theft, so clearly this thing is communicating, I just can't use any of the features that I'm paying for such as Wi-Fi, remote start, etc. when I called the OnStar advisor they're only advice was to go to the dealer, but when I went to the dealer they just kind of shrugged their shoulders and started talking about replacing multi-thousand dollar control modules when I don't think that's the problem here.
Thanks for sharing your experience with us. The best way to tell if there is a hardware concern with your vehicle's OnStar hardware is to look at the color of the LED light next to your blue OnStar button. If the light is green, you should be able to connect with an advisor by pushing the blue button. If the LED light is red or there is no color when your vehicle is on, there may be a concern with the hardware which needs to be addressed by your preferred dealership.
