Onstar Module Needs Replaced
I have a 2023 GMC Sierra 1500 Denali that I had to take in for a dealer for them to tell me the OnStar Module needed replaced. My vehicle is over the 36,000 miles so they quoted me close to $750 to fix it. This $80k truck is only a year and a half old! Mileage should have nothing to do with this part. How is this not something that is covered by GM and/or OnStar? Especially after reading about so many other brand new trucks having this issue.Account locked to Mexico
I bought my vehicle NEW and have never had an OnStar account until this vehicle, 2026 Chevy Trailblazer RS. Somehow my account is locked to Mexico and nobody can seem to fix it, even if i set up a new account with a new email my account is locked and it says it ineligible to migrate to the new email. I really think my sales person messed up my account, he was the one who originally set it up, and he was struggling with it from the start.Onstar Module
Hi I’ve purchased a Chevy Equinox LT in March. I’ve been very happy with it until last week(11/20/25). I was trying to start my car on app and was getting an error saying it can’t connect. I made an appointment to coming in. Before was able to get there my car wouldn’t start. I had the car towed to dealer Middletown NJ. They said I need a new Onstar module and it on back order with no ETA.Telematic module is out
I recently bought a 2023 GMC acadia slt, we bought this one because it came with 3 years of onstar and wifi. Not the only reason we purchased this one, but it was a major factor. Anyway we have had this vehicle since 3 days before Thanksgiving. And the telematic module is out and we can't use any of the features, even the sos doesn't work. It seems as if this is a common malfunction so why hasn't it been recalled? Why should we have to pay to fix something on a year old vehicle? My mistake was not buying it from a gm dealer so I am basically SOL. I want my onstar, my navigation and the wifi i was promised when I bought a 30000 thousand dollar vehicle that these features were included. If the part isn't available how are we to fix it? When are they expected to be in stock? Why isn't this covered longer than the 36000 mile warranty? If someone's vehicle has over that on it. It shouldn't be our responsibility to pay to fix something on a new vehicle that apparently is faulty with how many complaints I have found about the module and onstar not working.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.Telmatic Module
To Whom it may concern, I have a 2023 (7/1/23) GMC Sierra. The telematics unit was out for approx. 5 weeks before I had a dealer appt for another issue. They said i would have to work with Onstar to figure it out, so I was at the dealer and I did just that. Onstar stated that I needed to schedule an appt. with the dealer. The dealer couldn't fit me in for another topic that day. Two weeks later the dealer stated that it was the telmatics module. It was also on backorder. It was 7 weeks since the need for a telematics module which was out of warranty. There is no future appt for the replacement do to it being on backorder. based on my internet research there appears to be an ongoing issue with these late model Telematics Modules across multiple brands. My questions.... Shouldn't this be covered under warranty (the dealer stated the GMC would cover half) since it is Onstar related and I have a 3-year subscription to the service? I think Onstar needs to credit me the time on the subscription once the app starts talking to the truck again. There is no end in sight on when the issue would be fixed. I am looking for Onstar feedback Thanks, DLBuff
