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.

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.Reference: GM Authority Article

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

I’m experiencing the exact same issue as the original poster, and I’m beyond frustrated. I paid over $80,000 for my 2023 Chevy Tahoe, and I also pay more than $50 a month for an OnStar subscription. Not only was I never notified that this critical safety system could fail, but now I’m being told I have to pay $822 out of pocket to replace a faulty OnStar module?This is absolutely unacceptable.OnStar is advertised as a key safety and connectivity feature—and it was a major reason we chose this vehicle. For it to fail so soon, and for GM/OnStar to offer no support, is both disappointing and concerning. This isn’t a luxury add-on; it’s a core safety system. The lack of transparency, accountability, and support is inexcusable.I will be reporting this to the Better Business Bureau and urge others to do the same. GM and OnStar need to take responsibility for this widespread and costly defect.

My OnStar failed 2 months ago. The dealer (Henna in Austin Tx) has had my Silverado EV for 6 weeks waiting on the telematics part. They won't let me drive the truck until the part comes in because they say GM won't pay them to put the truck back together then take it apart again.

I have a Sierra 1500 Denali Ultimate 2022; the module failed yesterday. I called OnStar to find a solution. I was surprised to learn that they don't have knowledge or a position on this issue. I canceled my subscription. There is no timeline to fix it.
How disappointing after overpaying for this truck. This level of service is what makes me change brands.

It appears as though I have an uphill battle. My OnStar light suddenly turned from green to red and OnStar advisors have been unable to diagnose the root cause nor rectify the situation. I'm scheduled for 30k maintenance on my 22 Equinox soon and will bring it up at that time. I'm leaning towards canceling the service altogether if I get a $1k proposal to fix a problem that is so widespread and well known. Perhaps a class action would be an avenue to pursue

    I appreciate how quickly you were able to copy and paste the countless previous replies. Please forgive my skepticism seeing as how out of the sea of complaints, I've yet to come across one where its said that OnStar was able to assist in any capacity
