On Star module broken
Wow, there seems to be a lot of issues with these OnStar modules. I too have the issue on my 2022 Chevy Bolt EUV. It started out just being an intermittent issue and I tried to get it into the dealer, but they never answered or returned my calls. I finally got a hold of them after the OnStar unit failed completely and I did a bad Google review and complaint on the BBB website. They got me in right away to confirm the unit was failed. The service manager has a request in for the part, but it is on backorder and no estimate of when they'll get it. It is crazy that something like this part can be so critical to so many systems on the vehicle. I can't reply to texts, can't talk on the phone without background noise, can talk on any app based communications (i.e. my office phone number, Facetime, facebook messenger voice, etc...), don't have GPS signal, no Super Cruise, no auto updated time/date, no remote access through the app, and more. Just as everyone else has expressed...it is so frustrating. Definitely discourages me from buying another car with OnStar. I had a Silverado EV in mind, but I don't know now.

My dealer amazingly got the part in to fix this OnStar issue (Telematics Control Unit). It was $715 with the diagnostic fee, labor, and parts. Surprisingly my breakdown coverage through GEICO covered this part and I only paid the $250 deductible. Now everything works once again. It is still ridiculous that it is such a hard part for the dealer to get and that so many of them go out in the first place.
I have an issue with my 2024 blazer rs ev. I have had the Onstar module replaced in February right after I bought the car because it was giving me error message and since then I have not been able to get a update on my vehicle’s charging status nor can I use my car remote commands through the app. Nobody seems to know what is going on and why I have no app use! I want to make a complaint because I have been dealing with this since I bought the car and nobody can fix the issue.
