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.
$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.

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…
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.
