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 just bought a 2021 Yukon SLT with 69,000 miles on it. 9/25/2025. Got home and went to register my onstar and there is no green light. Looked on a coulpe forums and said to check all the fuses, did that to no avail. After doing some more reading and with all the others reporting I guess I have a bad module. You would think paying 50,000 for a vehicle everything would work. Of course the dealership is ghosting me now. If this is that much of a problem there should be a recall. Especially if its a safety issue. I’m sure onstar is losing money, who is gonna pay a subscription if you cant ever connect. VERY FRUSTRATING!!!!
Hello there, Scott. Your frustration is completely understandable as we'd expect the same after purchasing a 2021 Yukon. If you are having some troubles contacting your dealer, let us be the connection that can aid in setting up a diagnosis appointment to see what is going on with your OnStar services. If interested, please send a private message to OnStar_Support so we can look into this further. Just select the envelope icon at the top right of your screen to get started.
I was able to get in touch with the Service department, It will be a month just to get it in and look at it, but the dealership itself, the salesman or finance dept, has nothing to say so far. I will probably not ever deal with this dealer again.
We appreciate you bringing these concerns with your Yukon's OnStar module to our attention. This is not reminiscent of the OnStar and GMC experience which we hope to provide for our loyal members. Our team would like the opportunity to look into this further with you and your servicing dealership. When you have a moment, please send us an email with these details to socialmedia@gm.com with, "ATTN:OS Community/Jmarinelli00," in the subject line to proceed with this assistance. We hope to hear from you soon.
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 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 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??

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.

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!

Here is the NHTSA Safety Complaint form again if you need to report your module. It is a safety hazard especially if your vehicle SHUTS DOWN MID DRIVE… National Highway Traffic Safety Administration
