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.

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.
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!!!!
I also forgot that NOW the plan that I was promised with my purchase is not able to be delivered??? How is this my falut?

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??
