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.

GMC Sierra. Bad telematics module. No ETA from GM or the alleged manufacturer of the module. Also, no loaner vehicles. Unacceptable! They told me it isn’t safe to drive…after I questioned them, now all of a sudden it’s “ok to drive”. This issue seems like a class action lawsuit.
Same exact thing here on my 2025 Silverado.
I agree with a class action suit how do we go about this
I'm have the same problem. My 2024 Equinox Ev 2RS has been at the dealership for 10 days now and the told me there is ETA for the part.
We are currently going through the EXACT SAME ISSUE AND EXPERIENCE!!! We purchased our 2023 Yukon Denali last July and in November our OnStar as well as Wifi and other features quit working. These are one of the main features why we bought the vehicle. We have had to take it to the dealer 5-6 times already and it's the same song and dance, the part is on back order with no ETA. How is there not a recall already made by GM? Then to top it all off, we had to have the Yukon towed last week because it would not go into gear due to this model. So just like others, we are paying for a vehicle we can't use and an On-Star subscription that we can't use. This is extremely inconvenience and frustrating because we don't even feel safe with the vehicle anymore. Please GM figure our a solution for not just us but everyone else too!!
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.

These moderators aren’t helping anyone. They’re just doing their due diligence to GM and trying to keep you the consumer complacent and quiet by offering you their help. They make you do a bunch of things and have private conversations with you just to disappoint you and tell you there’s nothing they can do. They can REALLY HELP by doing something about it. Onstar being part of GM should push for a NATIONWIDE RECALL on this module… that would help!
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!!??
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.
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.
I don't think the warranty makes any difference? My car is 6 months old on a lease and they are doing the same thing with me.
That’s unfortunate to have to go 3 times.
i hope they get their act together soon because this is terrible
I’m sure it’s not safe to drive. I keep getting alerts while driving and it’s pretty distracting trying to see what the notification is

Exactly! How can GM not be handling this more efficiently.
My gas 25 Equinox's module gave out after 7 months as well. took it 5/2/25 to the dealership and they told me they have no idea when they can replace it. And that my covered warranty to replace it free expires after 36,000 miles but they can apply to chevy to get it free if I do go over the 36,000 miles but they couldn't guarantee that GM would approve it. Onstar needs to extened my free 8 years after it gets fixed if even it does for the months the model was not fixed. This is a safety issue if you get into an accident.
