App not connected to ONSTAR services
Hello, I recently purchased a 2022 GMC Sierra with the new infotainment system. In 3 short weeks my truck ate throw 3GB, I called ONSTAR for support and they blamed me. Apparently, my phone used all my data. The first girl said they have tools to figure out what used the data from the truck but I needed to call tech support. A few days later I call tech support to be told they don’t have tools to diagnose where the data was used and it was all my phone. 3GB gone and not a single app used on the truck. Then, I try to set up myGMC to my app to use the remote start. It tells me that my truck is not connected to ONSTAR services and to press the blue button, so I did. Just to be told the truck is activated and there shouldn’t be an issue. Over an hour on the phone and logged into the website numerous times, through every single page and nothing. The GMC website literally says my truck is NOT connected to ONSTAR services and there’s no place to link my account. When I try to activate ONSTAR on the website it says there’s an error and to call. How am I supposed to use the remote services when the my.gmc.ca says my truck doesn’t have ONSTAR activated, but ONSTAR is saying it is activated!?? Tell my why I’m paying for services that I can’t even use?
Same issue here. OnStar was activated but won't connect to the MyGMC app. I've tried everything suggested.

There could be several reasons why the app is not connected to ONSTAR services:
Poor network connectivity: If the device's network connectivity is weak, the app may not be able to connect to ONSTAR services.
Incorrect login credentials: If the user has entered incorrect login credentials, the app will not be able to connect to ONSTAR services.
Outdated software: If the app or the device's operating system is outdated, it may not be compatible with the latest version of ONSTAR services, resulting in a connection issue.
Maintenance or technical issues: ONSTAR services may be undergoing maintenance or experiencing technical issues, which could result in a temporary disconnection.
Subscription issues: If the ONSTAR subscription has expired or is not active, the app will not be able to connect to ONSTAR services.
Having the exact same issue with My new Malibu. Soooo frustrating. I've tried onStar for help and they gave me the "script" version of how to link and that didn't work because I didn't even have the options they listed in the first place. grrrrr

Add my 2022 Silverado to this list. $839 dollars, what a wasteful way to support GM products. GM should issue a recall and address this quality issue.

I've similar issue with my lyriq since 6-Mar-2025. I called OnStar support and they tried to restart the services remotely but failed to and asked me to go to a dealership for help.
Interestingly I found out that 4 other friends of mine (2 with Cadillac lyriq and other 2 with Chevrolet cars) are facing the same issue since 6-Mar. It's disappointing that OnStar doesn't notice the pattern and is not able to fix this wider issue.
After researching I found this community where similar issue have been reported since last 3 years.
