Here is the NHTSA Safety Complaint form again if you need to report your module. It is a safety hazard especially if your vehicle SHUTS DOWN MID DRIVE… National Highway Traffic Safety Administration

During a brief ride to the gym this mrning, I decided to update my Onstar, since it had a notice on my radio display screen. The nice lady explained all the options and I opted for the least expensive one ($14.99 per month beginning on 11-27) As soon as she entered the 3 digit CVC code from the back of my credit card to confirm my purchase, my vehicle SHUT OFF as I was driving. Long story short, it's been towed to my local GMC dealer and the service tech is ALREADY saying it's a coincidence.....which after a hot second of Google research, it's happening to many others...even the tow truck driver said he sees this 1-2 per week!!!

The telematics module when it began to malfunction drained my battery mid drive. I was on my way to work that morning. The AAA guy said something was severely draining my battery. The alternator tested good, he even suggested I shut the auto stop off. I got a jump and was good for two weeks then it happened again while I was at a stop light in NYC. Completely SHUT DOWN! I called AAA again. He tested my battery and said it was dead. My safety systems stopped working but my alternator was still good. He gave a jump, it started but the car idled funny. I made it home, bought a new top of the line battery, and took it to the dealership. They couldn’t tell me what was wrong. Two weeks after that visit my Onstar went out completely, safety features giving me all these crazy alerts, engine light on and off, I took it back to the dealership. It was the telematics module and hence my fight with Onstar, the dealership, and this nonsensical notion that I should pay over 1000$ to fix something that was failing for quite some time and never properly diagnosed. I’m out of warranty and was told it didn’t matter anyway because the module isn’t cover under warranty. My battery which I installed less than a year ago is beginning to drain again. This is a SAFETY issue and had I had been on the highway when this happened and probably will happen again then how am I safe? I can only pray other cars will be able to stop on time or get out of the way safely if it happens again. I have to drive. I live about 100 miles away from work and travel the highways daily. I reported my issue with the module to the NHTSA since I’m getting nowhere with Onstar, dealership or GM. I pray this doesn’t happen to you…

I’ve been closely following all posts and wondering why others are so much more impacted than I have been. The only symptom I was having was the CEL being on, or so I thought. That was until I read mscardona1’s post. I posted my story about a week ago; short version is I bought a used 2023 Buick Envision on 3/30/25, no warranty because it was a previous loaner with 49k miles, CEL came on 1-2 weeks after purchase, got the selling dealer to eat the cost of diagnosis even though no warranty, they said it was the battery and installed a new one free of charge, didn’t make sense to me because how could they have sold a car with a bad battery but ok. When I got home from that battery replacement (about 30 miles from dealer) CEL came right back on and same codes pulled. The dealer I bought it from was working with me but it became too much of a burden and cost to go back and forth 30 miles each way so I took it to my local dealer 4 miles away and they’re the ones who made the proper diagnosis of telematics module needed replacement. I paid for the replacement (total $1713.39) (just picked the car up on 8/23/25). What didn’t resonate until now is the bad module was why the battery was bad in the first place and it’s likely that I would have eventually run into the same problem as mscardona1.

Everything about OnStar and as far as I am concerned Chevrolet is terrible. There is no help anywhere. I have filed my complaint with NHTSA and hopefully enough other people have as well so that this can be looked into and a recall issued. These companies could give a rat's ass about the general consumer, unless they are forced to do so by an official agency they will sit by and let people get injured or worse.

I have a 2024 Denali Sierra HD and telematics control module just went out. WiFi,onstar,gps,sos and tps doesn’t work. I went in and they are charging me 1400 to replace that.

Is it not covered by warranty?

I picked my car up on Saturday (8/23/25) after having mine replaced. For reference my total invoice was 1713.39.

These “dealers” she be held accountable as well. They are knowingly selling customers defective products!!! Im so infuriated that i have over 80k brand new vehicle that i cant fully enjoy. Then to be insulted with the bs run around from onstar and the dealership is really icing on the cake. Back to Toyota i am going. Had a 2012 Sequoia for 11 years never had a problem at all. Only got rid of it because they changed the body and i liked it. After driving for a few months it was too small for my liking so i traded it for a 2023 suburbanz71 which didn’t have the module issue but i didn’t like the suspension. Traded that in for this 2025 with air ride suspension which the ride is better than the 2023 but nothing like the smoothness the Toyota had even at 11yrs old. Now i am stuck with this thing i am unhappy with. I should’ve listened to my husband and kept the sequoia:((

Switched dealers because of this and because they refused to further diagnose. Got the run around, got a couple of lies like “oh I never heard of this before” and then left when they wanted me to pay for something that one I didn’t cause, two was faulty nationwide, and three that was not covered under warranty even if I had it still. Dealers are in the business of making money but GM is making these cars and need to make moves. Dealers won’t touch it unless you’re paying or if GM is paying, like I said they only want to get paid. If you die or crash they don’t care, as long as they weren’t the cause and they aren’t. This is a manufacture issue, a faulty product that affects safety features, the safety commission needs to be involved in this as well. This won’t stop unless GM does a Nationwide Safety Recall. How about the Federal Safety Commission on automobile safety???
dealers will keep selling these cars for as long as GM keeps making them. Unless things stopped at the assembly line then we are going to continue to have these faulty vehicles flood the market. Once you buy it’s YOUR PROBLEM and not theirs… that’s where the BS is…

I have a 2023 Suburban and a 2023 Yukon with the same problem. The Yukon offered a free OnStar module replacement through a friend program, but rejected to do so for the Suburban, which now costs $1,140. We should organize and sue GMC for this irresponsible behavior. This is clearly a product defect, and GMC must have known about it, yet they've done nothing, leaving owners with the hassle of dealing with dealers and even having to pay for the replacement themselves. It's time to make GMC pay.

There’s talk of class action but no one has really organized with a lawyer yet. I’m thinking state attorney generals for each state affected but it seems like this is a Nationwide issue. While I’m unfamiliar in this field of law I wouldn’t know where to begin. My 22 Buick is out of warranty and this repair isn’t covered at all. ONSTAR will try to reach out to have a private conversation but it is a waste of time. Remember, ONSTAR is a product of GM and is in ALL GM VEHICLES. No way are they going to go against their parent company.
GM needs to issue a NATIONWIDE RECALL. Some cars are shutting down completely, some are drivable but lack some of the safety features because the faulty module is malfunctioning the safety system causing alerts, service engine lights, and drainage of the battery mid drive. This is a dangerous and hazardous condition to drive under if driving is mandatory, like it is for me. They say “you’re fine” to drive like this but there is a potential for bodily injury if the car breaks down mid drive on a highway with no warning. Someone is going to die or get seriously injured… is that when GM is going to do something about this? They have no problem paying billions out in settlements for wrongful deaths rather than fix the issue to secure lives. This is NEGLIGENCE. It needs to end.- CarCat59Contributor
I contacted my State's Attorney General. I have to start somewhere. Hopefully they can provide advice on how to proceed.
