my 2025 Equinox EV (4000 miles) also has a failed Telematics module (as of 2.1.25) with a "backorder" status and dealer has no idea when it'll be in. Not only does it affect OnStar, but gps/maps/charger near you dont work either. You have to guess and figure it out manually. The car thinks I'm hundreds of miles from where I actually am and doesn't change location. This is unacceptable in any vehicle, but especially an EV which relies on the information to travel

GM... WHEN IS THIS GOING TO BE FIXED? 4.5 MONTHS NOW I'VE BEEN WAITING! DEALER IS AWARE BUT NO UPDATES ANYWHERE!!!!!

So frustrated! After my telematics module failed on May 22, I was told by my dealer that it’s on backorder with no ETA. Then, just days later on May 26, I get an email from OnStar saying my Safety & Security services have expired. How does that make any sense?I’ve spent countless hours explaining my situation to multiple people, and Still no fix and now I’m stuck waiting indefinitely for a part that has no ETA.To make matters worse, I was under the impression that my free OnStar plan would stay active until the module was replaced, yet here I am with expired services and no working OnStar and GPS. OnStar even told me to sign back up for paid services in that email, but why would I pay for a system that doesn’t even work?I bought a brand-new 2024 Equinox EV, moving from a Japanese maker, and this is the experience I get? These connected vehicle features were a major selling point for my purchase, and now I don’t have them. No ETA is completely unacceptable—how long am I supposed to just wait? GM and OnStar need to provide real answers, not just the same scripted response of “backordered” and “no ETA”.Anyone else dealing with this mess in Canada?

There might be hope out there....I was pleasantly surprised to get a call from my chevy dealer this morning telling me my telematics module is in! I have an appointment for 2/25 to get replaced. Fingers crossed.

So the module came in June 5th, 2025. Spent 6 hours at the dealership because the service tech could not get the new module to accept the software codes. Now our new car, with approximately 2600 miles on it sits at the dealership until a GM Computer Specialist from Detroit can come down to manually write the software into the new Telematics Module. I've had a past practice of purchasing a new car every 3 to five years since 1974, and have never experienced this type of inconvenience and continuing nightmare of life-disturbing events.

We are having the same experience and about the same time frame but in Washington State. We bought a brand new 2025 Equinox EV Nov 30th, 2024, the Telemetrics module failed May 28th, 2025, and was confirmed June 4th by our Chevrolet dealer. Today what I found out is a company called Specmo (Specmo [Wholesale and OEM]), is the sole supplier of these modules for GM. When I go onto their website, I think they refurbish components and are not manufacturers. I have posed this question to Specmo and hope that I will have an answer next week. A side note, I queried who are telemetric manufacturers and Specmo is not in the top 12, so I'm a little suspicious of the claim Specmo manufactures these modules. One thing for certain is my expectation is to receive a new part not a part that has been refurbished one.

I’m not happy to find that this problem has existed before I purchased my vehicle 2025 Arcadia Denali. Now I’m line with all theses people also. All my problems started when I was asked to update my system. If you knew the problem existed. Why would the system ask people to update their system? This sounds like it’s going to fall under the Florida lemon law act. I’m a very dissatisfied customer and plan to file what ever it takes. This is a nightmare I’m in fear every time I go out of town because my system does it’s own thing. I have already went through OnStar for two hours and then took it to be serviced only to find out my part is on backorder.
