OnStar Module Broke

Question

Brought my 2023 Yukon XL with 38K miles in to fix a recall and when I got it back now my “telematic control module/OnStar module” is broken and needs to be replaced. Dealer is telling me it will cost $900 and they have no idea when the part would even be in? This is ridiculous, not only should I not have to pay for this, but it shouldn’t have broke and if it needs fixing it should be done immediately.&nbsp;

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.

I am having the exact same issue.&nbsp; I have a 2022 Yukon XL with about 40,000 miles.&nbsp; I brought it in for oil change and "updates," and on my way home from the dealership check engine light came on, and no Onstar services work.&nbsp; They are now telling me that the Onstar telemetry module needs to be replaced, at my cost.&nbsp; This is obviously unacceptable in an $80,000 vehicle.
