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.

Welp.. I Joined the club. It appears my Telematics module is dead as well. I've had nothing but electical issues since i've picked up my 2024 GMC Sierra 3500HD. been to the shop several times. It's the Duramax so I have two batteries. Usually I drive it daily so it's always starting and charging, well, didn't drive it for four days it didn't start, dead, clicks and all. Had all types of problems after I recharged it (as yall already know) but after a complete disconnection of the battery for a day (discharging the caps) It was fine. a few months later, really slow to turn over but finally did start... a few minutes later after driving, check engine light came on. On star no longer lights up (no green or red light), and no 4g LTE. Checked the batteries just to understand their state. one battery only has 550CCA (very low for a 730cca battery) and the other had 64... 64CCA (I'm checking CCA because it's below freezing where I'm located at the time. So it sounds like that "fix" drained my battery and from what I read, the TCU is EXTREMELY sensitive to voltage.
I have to chat with the dealer and GMC, but I've had the truck less than 3 years, still have 8 months on my OnStar Subscription and infotainment is completely useless. I don't know how far it will go since I'm over 36,000 miles.

Same issue, same answer where I must pay for something that I bought with the truck, unacceptable in every aspect. GM makes enough money to cover their sub par equipment. Want ON star back as Ai was promised on day 1

Same thing happened to me on both my GMC Sierra Denali 2023 and my son‘s truck 2022 Chevrolet Silverado LTZ contacted OnStar absolutely no help the plan on my GMC is that three year thing is still in effect which should cover it, but these faulty products should be covered by the company for both my pick up and my sons. This is ridiculous. We need to find an attorney who will take a class action suit and hold the company responsible for these faulty products. Contacted the dealer today. They informed me that it would be $1000 each to replace them ridiculous.

Just had the same thing happen to me with the exact same truck. I've had mine 2.5 years but out of warranty because of mileage. It is frustrating to not be able to use the phone app because there is no data connection. The built in navigation does not work either. I guess no more over-the-air updates, too. These should be replaced regardless of mileage because 1. they fail so often and 2. they do include some important safety features. It is not as if I was too hard on the Onstar module like someone could be with a motor or transmission. I'm surprised someone has not been stranded in a blizzard, not knowing where they are, ended up with hypothermia but could have easily called Onstar for help and so their location would be known, but pressed the Onstar button only to find it dead.
I do see Onstar's side of it, though. There are probably a lot of people paying for Onstar but do not know their unit is broken because they have not had to use it. That's just money coming in every month without Onstar having to provide a service in return. Hell of a business model. I wish I would have thought of it.

write to the NHTSA I did. You are right about someone being stranded and Onstar is not working even while paying for the subscription. This a safety concern.
Same here 2023 Yukon AT4 50,000 miles and charging me 800$ for the module very frustrating considering that I paid almost 90k for a couple years ago

OnStar_Support still has no resolution, nor will they continue to provide support for the issues.

This law firm is currently in class action litigations with GM for faulty engines…

NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION!!!Yes yesterday I filed safety issue on the NHTSA.
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.
