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.

Looks like I am joining the group! 2024 GMC Sierra 2500. Took my truck in for the 15,000 miles service and they went to complete some warranty work. They weren't able to do that since they discovered the telematics module is bad. They supposedly ordered and I dropped off my truck back off on the 6th of May. Went by today (7 May) and the part is backordered with no ETA.

@Advisor_Helen it would be great to solve the backorders at the dealers as that seems to be a problem.
Same BS just happened to me. Dealer has had my 2023 Silverado for two days… I told them exactly what it was based on these threads. Lo and behold after two days they tell me telematics module died (no sh-*t Sherlock)… no ETA on replacement, and want $1,000 to fix a KNOWN issue. Anyone know a good class action lawyer because this has it written all over it.

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.

Exactly! How can GM not be handling this more efficiently.
Same for my 2022 Chevy Tahoe Z71 -everyone I see on here has been waiting months. Only 1 person so far that I saw got one after a couple months.

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!!
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.
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

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.
That’s unfortunate to have to go 3 times.
i hope they get their act together soon because this is terrible
