2025 equinox ev- OnStar Telematics module - no dates for backorder part is unacceptable
I recently bought equinox ev 2025. In 5th month of use, telematics system stopped working. Dealership mentioned that part is nationwide back ordered with no estimated date. And i saw on many portals where same issue has raised by many car owners. Is this normal to have this part back ordered with no estimated date. And if GM knows the problem with this part, why are they selling such cars. Is there a way to raise this concern with any federal department?

This is currently happening to me. I traded my 2023 Sierra on a used 2025 Sierra EV last week and was not able to setup OnStar after multiple attempts. Onstar green light is solid but it doesn't connect. Dealer I bought it from diagnosed a bad telematics module yesterday (6/18) and placed part order. I also found a Service Bulletin issued May 26, 2026 that stipulates dealers are not to sell any new or used vehicle with this issue. Obvious the dealer I traded with is ignoring this communication from GM. Very frustrating experience since without Onstar the on the road EV related features do not work like navigating to charging stations or estimated charge on arrival. Given the posts in this forum I don't have confidence my wait for a fix will be short.

My OnStar’s been out since January 2026. Called 2 dealerships, got the same answer….nationwide back order. What does that mean???? Just make more for crying out loud!
Hey… my OnStar module has been out since 2024!!! Still haven’t gotten it fixed… 2 YEARS my Buick is useless without the features this MODULE controls. I’ve written about this on many other threads over the years, I’ve reached out to government agencies, spoke to GM reps in headquarters, reached out to State Attorney General… It’s an outrage that this isn’t covered under LEMON LAWS because this module controls many SAFETY FEATURES in the vehicle not to mention WIFI and CONNECTIVITY. Good luck trying to get it fixed at no charge if you are out of your POWERTRAIN warranty… So that means after 36,000 miles this car became USELESS. Speaking to OnStar was my FIRST DEAD END because they did NOTHING to fix or help the situation… Just wanted to give you a heads up on what to expect from these people. Just waiting now to gather enough DOWN PAYMENT to go into something else… I’m thinking TOYOTA is the way to go!

My family bought 2 equinox ev's... a few months later it updates. And suddenly so far for 5 months the telamatics on star module that controls MOST of the cars is completely useless. Finally got one fixed it took 2 months to get the module now in the middle of having the second one doen and its going to be another 2 months. I AM PISSED. Should have been a recall since the update that corrupted it was from OCTOBER OF 25. ABSOLUTELY UNNACCEPTABLE
@Raygiff Our team hears your frustration. We remain a private message away for any further assistance that can be offered.
This just happened to me last night. WiFi wasn't working for the kids and no response at all from the OnStar button. I called OnStar from my cell phone and they were unable to help and said I needed to take it to the dealer....................the same dealer whom I had an appointment with to update the software from the recall, but failed to call me and let me know that they were not going to open because of snow. I drove all the way there after a snowstorm to find no one in the building and no one even answering the phone. No phone call ahead of time to tell me they weren't going to be in. I wouldn't have wasted my time going and now a week later my telematics module is out, what a coincidence (which is literally what the person from OnStar said when I questioned her.) Not to mention now reading from others that the fix cant even be done because there is no timetable for replacement parts. Really frustrating. Poor job by GM and OnStar.

I have had my 25 Equinox EV RS for 8 months now. The telematics and OnStar stopped working back in October. My household has 2 Equinox EV's and both had the telematics module take a dump. NO MAPS, NO INTERNET, NO ONSTAR CONNECTION, NO CRUISE CONTROL, NO APP CONTROL. NO CHARGIN LOCATION SERVICES. AND PHANTOM E STOPS IN THE MIDDLE OF A CLEAR ROAD! Took one to the dealership and had to wait 2 months for a replacement. I know GM is slowly becoming a subscription based company but you won't make money if your apps are worthless for months at a time!
Everyone who is affected by this should make formal complaints with the federal departments.

I, too, have the same problem.
The On star module is backordered, and we are just waiting with no ETA.Is there any update on this? (I have a 24' Equinox EV)
I am having the same issue. 2025 Equinox and it completely drained my car battery. Was told today that there’s over 4,000 affected. Definitely should be a recall.

I have the same problem with my 2025 Equinox EV. The dealer diagnosed it as a Telematic Control Module with a no ETA. This is unacceptable. I have none of the safety aspects of the OnStar system. I can’t use navigation. I can’t find a charging station. I can’t see or control anything through the MyChevrolet app. No over the air updates. I have no idea when I will receive the part. I have only 3,500 miles on the car. Not a happy camper!

I am just starting to have this issue - this is kind of scaring me. I bought my 2025 Equinox Activ back in March and two weeks ago this issue has started to happen, but it is connecting maybe after a couple of hours into the day. I had it in the shop yesterday (10/16) and said it was a system update that needed and they did that, and when I got in the car it connected to everything right away - got in it this morning to go to work and I get Cannot Connect to Onstar, which in turns not allow me to connect to Wi-fi and throwing the Nav off. Is this what I have to look forward to in getting this repaired? Part of me wants to cancel my service. This is just not acceptable in a 2025 vehicle. Why is this part on back order? Why has a Recall not been declared? Is the current Tarrif's causing the module to be on backorder? I have had Chevy's for the last 17 years (used to be a Ford person) and I would much rather have a Chevy but I would trade the car in a second if I have to start dealing with these issues.
Try pulling the onstar fuss its F8 on my fuss box under the dash see if that stops the drian
This isn't the experience we hoped for you to have with your new Equinox. We know how vital it is to stay connected on the road, and we realize that repairs that involve part delays can be stressful. You did the right thing by bringing this concern to the attention of your dealership, and our team is glad to connect with them to offer further support. If it interests you to have our assistance through this process with your vehicle, feel free to private message OnStar_Support with additional details. Just select the envelope icon at the top right of your screen to get started.
This is not the experience I was hoping to have with my new Equinox either. How about you buy it back?
Has anyone thought that these modules are not made here? I suspect that they may be coming from China. This whole situation might be caused by our current trade situation with China and that may not be resolved anytime soon. Some of this delay may be GM trying to find another source.
I just wish they would tell us exactly what the hold up is.
This module is a defect and definitely a SAFETY issue. The telematics module has the potential of draining the battery completely which can cause the car to shut off MID DRIVE. I know because it happened to me TWICE.
I have reported the safety issue to the NHTSA
https://www.nhtsa.gov/report-a-safety-problem#/vehicle
I have also reported this to the Federal Trade Commission because it is fraudulent practice to advise consumers that these vehicles are still safe to drive.
https://reportfraud.ftc.gov/assistant
Many of us have contacted GM DIRECTLY to file a complaint at
We have also contacted a Class Action Lawyer based out of Philadelphia that has gone up against GM before. Speak with Michelle
UPDATE: GM called me back to discuss this issue twice and they are trying to contact the dealership for payment assistance options.
This is currently happening to me! I had to have my 2025 Enclave jump started twice this weekend! They said there a backorder for the module necessary to repair the vehicle.
Jennifer, your disappointment with this situation has not gone unnoticed. As soon as you have a moment, please send a private message to OnStar_Support with more information so that we can look further into this.
I contacted GM and they said its not a widespread issue and all i can do is wait.
that's what they want you to think. This is happening to so many people from ALL over. There's a few fb groups about chevy equinox problems, if that's what you have, and most of the complaints I've seen are about this module. Do not let them dismiss you. We all work hard for the things we have, your safety isn't a gamble. Push the issue.
