Telematic Control Module needs replacement, but backordered with no ETA?! UNACCEPTABLE
My 2024 Equinox EV 2RS (Purchased brand new in November '24, only 1,568 miles on to-date) is now in the dealership for the third time due to what was thought to be a 12v battery problem. Turns out, it was a faulty Telematic Control Module that needs replacing, and the dealership that's working on it says GM has no timetable/ETA for the part?! The amount of posts on here reflecting how frequently this is happening should make GM want to have THOUSANDS of these parts on hand for immediate deployment, not arbitrarily informing dealerships, "There's no ETA." I'm a new mom and back to work for the first time since giving birth in October, and being unable to count on a vehicle to simply work is beyond defeating.

Just got my 2024 Equinox EV back from the dealer. Had to wait about three weeks for replacement telematics control module to come in. Not too bad. Took about two hours to replace. Everything works great now and I just hope it stays that way!

Same issue here with the 2022 GMC Sierra Temematic Control Module
right at 3 years of ownership. Actually did not notice this for some time since I rarely use onstar. Now I am having to spend my money and time to this replaced. Dealership quoted me $700...Our team understands how frustrating unexpected repair costs can be for our loyal drivers and appreciates you reaching out to us directly, @Tylerpate.

Has anyone thought about taking this to the MEDIA? News outlets? Reply if you have connections… I’m camera friendly.
Good to see the moderators on here copying and pasting the same reply. I don't think it matters if the vehicle is under warranty or not as mine is under warranty and I am getting the same old song and dance everyone else is. I called last week, and the dealer still has no ETA. I asked if there's a way to elevate the issue and they mentioned the backorders automatically ping GM. It's obviously not helping so maybe one of these moderators can help!!??
NATIONWIDE RECALL. That’s the only way we will get something done with this issue!
They say they will help you, they say they will communicate with the dealership. But these moderators aren’t doing anything unless you still have a warranty. They offer cost assistance ask you to give them a quote and to send them the diagnostic information only to turn around and tell you they can’t help. Why make the consumer go through all of that with false hope just to be let down again. It’s bad enough the module isn’t working, plus they want you to keep your service in order to help you so you’re paying for service that isn’t working, then they disappoint you again… NOT FAIR AND UNACCEPTABLE.
so they do not cover any of the cost at all?
I've been reaching out once a month to see if there is an update. I was told the part number changed, but that it is still on backorder. This is the most ridiculous thing I've ever seen. Are they just not making that one anymore? Is there a new, updated one we should get as a replacement?
NATIONWIDE RECALL… let’s demand GM issue a RECALL on these modules.
Same experience. Telematic module has failed . Confirmed by our dealer with part backordered with no ETA for part. 2025 Equinox EV level 2 options.
I would like to know from OnStar: What is the failure rate for this module?
Will the replace module have 5g instead of 4g? This module has been in production since 2015.

is onStar paying for the replacement since it is a known issue?
Sameboat. 2025 Chev Equinox EV 5000 miles on it. Week 2 with no replacement in site. GM should acknowledge what the problem is. Design or supply. It is my understanding that the same module has been in production since 2015, using 4G as cellular service. Are they about to release a new module using 5G service?
I have a 2024 Traverse with 2200 miles on it. At 1500 miles I noticed I couldn't turn on the data sharing hot spot button (greyed out) have been on the phone with OnStar several times and had it to the dealer several times. Yesterday I sat at the dealership for 3 hours while they replace my Telematic Control Module. They said it was all finished. I tried to turn on the hot spot sharing data button and it still doesn't work. So even replacing the module didn't help!!!

Hey everyone! Just wanted everyone to know that if an Onstar representative reaches out to you and says they can help you chances are THEY CANT AND WONT… unless your car is still under warranty. My car is a 2022 Buick Envision. I have A LOT of highway miles on it… that’s why finance… my module went out in DECEMBER. Just recently a rep said they can try to help me… I even go as far as sending them a QOUTE! Well guess what…after all that back and forth the ONSTAR rep tells me they can’t help me with this because I’m out of warranty! If I still had a warranty we wouldn’t be having this discussion right now… I’d be getting the problem fixed. The whole reason for reaching out in this forum was to try to get some help…not to be told something I already know! It still doesn’t EXCUSE the fact that my car is LESS THAN 3 years old with a failed Onstar module! The part is on back order, the dealer wants to charge $1000+ to fix, and I’m STILL paying for service I don’t have SINCE DECEMBER! Does everyone see the issue here? It doesn’t matter that I’ve been a loyal customer to GM for over 30 years, it doesn’t matter that I’ve paid for the premium packages in EVERY VEHICLE I’ve owned with Onstar, none of that matters. No one cares! I think it’s time to say goodbye to GM and go with their competitors and forget Onstar altogether!
GM needs to step up their A game and issue a Customer Satisfaction recall on this module before they lose consumers by the droves! Shame on Onstar! Shame on GM!
if people are still planning a class action lawsuit IM ALL IN!Hello did you ever receive the part? I would really like to know. I got a a new 2025 Tahoe and did it because of the entertainment and I can’t use it. I really would have stayed in my Toyota for this.
No part. No help. Just utter disappointment. Time to hold GM and Onstar by GM accountable. Issue a RECALL….
Quick question for everyone in this community… Before your Onstar modules went out, did anyone have a Park Assist Retrofit module installed as part of a GM recall? Did your Onstar module fail within a few months of the install? If so let me know… I think I might have something here as to why our systems have failed if so… Doesn’t fix the problem but at least i can confirm a cause if it is so…
$97,000 GMC 3500 Denali that sits in the driveway unable to be used for what I bought it for...TOWING! Why? The faulty Telematic Control Module causes the trailer lights and brakes to not work. How silly is that! Found this out the hard way by getting pulled over and luckily without incident. Not having Onstar or navigation is one thing but not being able to safely tow is a much bigger issue. So now my Sierra with 7,700 miles on on it sits while I borrow or rent a tow vehicle to be able to tow trailers for work. Dealer's hands are tied and can't get mad at them for GM's complete irresponsibility on this. Once accidents and injuries happen (if they haven't already) hopefully this will get resolved. Meanwhile the frustration is building
Dang, I’m now a newbie to the group. Had my 2023 GMC Sierra AT4 in yesterday and received the same “bad telematics module” diagnosis. Hopefully we all will get some relief soon. I was given the okay to drive it, I let my onstar subscription expire and won’t be towing my boat for a couple of weeks so fingers crossed the parts Start to ship soon.
