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.

We would like to look into this further and provide a layer of support between yourself and the dealership throughout the process of these repairs. Our utmost priority is to get you back happily on the road in as timely a manner as possible.

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 lawsuitWe do regret to hear of any ongoing concerns with your vehicle.

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.

NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION!!!I’m at the dealer right now and was told the exact same thing. $500 plus labor to replace the telematics control module. Dealer confirmed there’s no sign of wear or reason this would occur. When I asked for a timeline of replacement part availability, he said they don’t know and they’re currently back ordered. Lack of availability tells me these 2022 Yukons are experiencing the same thing. 35k miles on a 2022 Yukon SLT, the warranty expired 2 months ago. I’m expecting a GM moderator to support this!
I hear your frustration. After numerous phone calls to ONSTAR one advisor suggested I try a different GM Dealer and they too said the module for my vehicle was discontinued. So, I took it upon myself to reach out to YORK ELECTRONICS LTD. (the General Motors authorized Electronics Service Center in Canada for automobiles here in Canada) to inquire about a module for my 2012 Chevy Equinox. To my surprise I was told that the module was available but is now listed under a different part number. I had the dealer order it and the cost plus installation was slightly over $800. Now that it’s installed ONSTAR still can’t connect my vehicle with my current subscription plan. They keep telling me they are running into technical problems at their end. We should be getting better service for the price we pay for this service and the replacement cost of these modules. I hope your dealer can help you with your issue. BWZ

2023 Yukon just passed 40k miles at 30 month old so NO Warranty and this will be a you problem and not an US problem. How can basic technology fail!!! after minimal use on a $80k vehicle. I have owned 6 YUKONS before this one and NEVER had an item like this fail. The dealer has told me that this $800 repair parts are on special backorder/ allocation...this sounds like a recall/ design issue and not a cost that I should have to pay for a still relatively new vehicle. So until this is repaired, no ON STAR, NO SAFETY NET, NO WiFI, NO EMERGENCY all items that are basic and EXPECTED... why, why , why? Seems like a much bigger issue that I realized with a simple fix.....H E L P!!!!
This happened to me back in February and my local dealership JUST called me to let me know the part is in smh. I also brought my vehicle In for an oil change and a day or two later my check engine light is on my truck that has less than 50k miles. Super frustrating since my OnStar service, remote start services aren’t able to be used due to this.

I’m not paying for it. This isn’t my doing its a problem that OnStar or GMC that they put faulty and cheap parts in my truck. Also, someone sent the part back they said. The lack of accountability is awful.
I think we all can see this is happening to many owners, the common response is how surprised they are and please contact to assist. I save you the trouble they will do absolutely nothing, it’s a run around.
Yeah OnStar as a company is a complete joke. They use cheap parts and when an abundance of them start going out they don’t own up to it. I’ve seen class actions like this for other things.
I also contacted the law firm and left my information with Michelle.
