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.
