OnStar Module Broke

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.

    I am having the exact same issue.  I have a 2022 Yukon XL with about 40,000 miles.  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.  They are now telling me that the Onstar telemetry module needs to be replaced, at my cost.  This is obviously unacceptable in an $80,000 vehicle.

        I'm writing to report an issue with my OnStar service in my 2022 GMC Yukon SLE. When my vehicle was parked, I attempted to locate it using the OnStar app, but the service wasn't working. Upon starting the engine, I noticed the OnStar green light was not illuminated inside the vehicle.

        When I contacted OnStar support, they suggested it might be a hardware issue. However, I've noticed this problem seems to be widespread. I kindly request that you investigate this matter further to resolve the issue.

    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 will not for the life of me understand HOW 98% of complaints are about the exact same thing and no one is doing anything about it. 
    I have a 2023 Yukon XL, and it just suddenly started out of nowhere, the internet stops working, the engine light comes on , take it to the dealership and they said $ ohh it’s your OnStar computer it needs to be replaced. $buy the computer and labor $600. First of all why is the computer broke? This is a 2 year old vehicle! What is wrong with these companies? This is absolutely unacceptable. This is a lawsuit
