2023 Tahoe Z71 Telematic Module out

I have a 2023 Tahoe Z71 and the Chevrolet GM service dept just told me the telematic module for the OnStar is out. They are checking to see when they can get the part but have no date.  I see a ridiculous amount of complaints on here about the same thing with no resolution to the problem.  It’s very disheartening.  We paid a stupid amount of money for this vehicle and have been on a premium OnStar subscription plan but have had no service for 5 weeks. Now I’m being told they don’t know when the part will be in?   At this point I’m thinking I don’t want to ever buy another vehicle equipped with OnStar.

There appears to be a widespread issue with the telematics module. I own a 2022 Cadillac Escalade, and my telematics module is not functioning. When I took it to Covert Cadillac in Austin, TX, the dealership informed me that I would need to pay approximately $460 just to have the module scanned to determine why it is offline—before they could even diagnose the problem or suggest next steps. Additionally, I was told that my extended warranty would not cover the module.

I agree with other customers that this issue needs to be reported to the Better Business Bureau, and legal action should be considered. It is unacceptable for GM to ignore this recurring problem, especially since Cadillac issued a recall for the same issue back in 2021. Clearly, the problem was never fully resolved.
