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.

My 2025 Yukon AT4 with 900 miles module failed. I had it for three weeks. No ETA and it’s been at the dealer for 6 weeks. I don’t know what to do.
This is the latest response I got from OnStar. What a joke they are!
We understand your frustration, Carla. Please know, that when an attorney is hired, our customer care teams will no longer be able to assist with your concern. We do see that you were referred to your dealer by your case advisor, and to reach back out to them if you had any questions or need further assistance. If you needed any further assistance, we recommend reconnecting with them by calling 1-888-4ONSTAR (1-888-466-7827) or push the blue OnStar button inside you vehicle. I told them. YOU HAVe BEEN NO HELP. I HAVE CALLED AND HELLO- THE BLUE ONSTAR BUTTON DOESN;T WORK!!!
Wow! Is that a threat? You’re still a paying customer for their service and they do not have the right to refuse you assistance just because you are consulting with an attorney about a particular issue… Their empty threats won’t make a difference anyway because they can’t and won’t help. I tried to get assistance from them as well, in the infamous “PRIVATE” chats, and after sending them quotes, giving them the dealership info, and sending them all of the transcripts of conversations I had with We Are Listening GM Representatives, they finally told me they couldn’t help me because my warranty wouldn’t cover the repair and that I was out of warranty anyway. So don’t feel bad… The care team doesn’t care ANYWAY!
What i did i stop using onstar cancel my subscription and since lot of vehicle have same issue and no recall from GM issue , its their faulty equipment and now they are wasting our time at dealerships , what a decline GM , i wrote 6 7 month ago and issue is still there ,
I have a 22 Yukon XL Denali and when it hit 38K miles as well, the Telematic Control Module ALSO stopped working. I contacted the dealer and they informed me that I would need to bring it in for a diagnostic test, but that it was around $800-900 to replace. My car just ran out of the warranty. So I have just gone without. Today, my dealer sent a mobile technician to my home to look into a recall for an over-the-air update, that could potentially drain the battery affecting vehicle performance. They were not able to update my vehicle becuase of the Telematic Control Module is not working. Now that I am reading that EVERYONE has had the same issue, I agree that GM should be replacing these at no charge. What a mess! Now we also have to deal with the fear of a sudden loss of propulsion. I would truly appreciate if GM would address this issues for us.

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.
I agree I bought this vehicle again bacuase it saved my life and instar got the the emerncy services there in mins. I too saw check engine light and then it didsappers went to gmc nothing. I'm then one day I notice I could start my Yukon with the app. Come to find out onstar is down. Charge to service this hardware is nuts. Also the deal stay it would have to stay over night.

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 have a 23 Yukon Denali, my GPS and internet just stop working. After contacting OnStar, I was advised to take to dealership. My service advisor just messaged me that this same modular is out and it $800 to fix. I just did a google search to see if this is an commom issue. I found this chat. Why isnt GM taking care of this??

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!!!!
I am having the exact same issue, went to the dealership and yup same exact thing and now my engine light came on when there was no issue previously. GM needs to do better. My Yukon Xl 2022 is on three years old what in the world is going on?

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

Your cooperation and understanding on this matter are appreciated.
My ONSTAR module needs replacing on my 2012 Chevy Equinox with about 146,000kms. So after 13 years I guess things wear out. However, I still have an active plan. So, back in June of 2024 I was told by an ONSTAR technician I probably needed a new module when they couldn’t tweak things from their end. After taking my vehicle to my regular dealership I was told that the module was discontinued. In their effort to help they contacted ONSTAR and their technician told them to try a hard reboot. It worked for about a month. More recently, because my plan is still active, I contacted ONSTAR again about my module being discontinued and they suggested trying another GM dealership as they thought it was odd the module was discontinued. After contacting a different GM dealership they too said the module was discontinued based on my VIN. So, I took it upon myself to contact the manufacturer of these modules and was told that the part number had changed and that they did have a module with a different part number that would work in my vehicle. The only drawback was the module had to be ordered and installed through a GM dealership. I was quoted a price of $575 plus another $200 (+ taxes) to install it. Like others this seems expensive and ONSTAR doesn’t seem able to do much when it comes to pricing.
Our team appreciates you bringing this concern with your 2012 Chevrolet Equinox's OnStar hardware to our attention, @BWZ. The satisfaction of our loyal Members is very important to us, and we want to make sure that this trouble is resolved for you so that you can get back to what really matters with the connected services you love and depend on. For your awareness, our wireless network providers have transitioned their cellular towers in the U.S. from 2G networks to 4G or 5G connectivity. The transition was completed on December 31, 2022. After this transition, 2G network connectivity is no longer available. The decision to sunset these networks was made by the wireless network providers and the need to upgrade to newer technology. Certain 2015 and earlier GM vehicles on the road in the U.S. today currently leverage the 2G network for OnStar connectivity. For this reason, these in-vehicle connected services are no longer compatible with the technology equipped in your Equinox.
This does not mean that you can't still continue to take advantage of our amazing OnStar safety services. To help stay connected after the network sunset, our team encourages you to download the OnStar Guardian™ app. This impressive app allows our Members to take the safety and security of key OnStar services wherever they go.

Hello Jack: Regarding your comment: “The decision to sunset these networks was made by the wireless network providers and the need to upgrade to newer technology. Certain 2015 and earlier GM vehicles on the road in the U.S. today currently leverage the 2G network for OnStar connectivity. For this reason, these in-vehicle connected services are no longer compatible with the technology equipped in your Equinox.” While this may be true in the USA I have been told this is not the case in CANADA. My vehicle was upgraded to 4G Network. Since the new module was installed it will tell me that my vehicle is in demonstration mode connected by a 4G Network. However, ONSTAR can’t seem to connect to the module so my dealer who is working with YORK ELECTRONICS, the mfg of this module in Canada, is looking at replacing the module in hopes that it will work.
