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.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.Bring back the weather app!
I discovered yesterday that the Weather Channel app has been discontinued. I'm not happy about this! I use this app constantly. It's really the only add on app that I use in the car. I love it when I'm driving long distances alone and I need to check the weather. It's so much safer to look at the radar quickly on the screen vs trying to pull it up on my phone while I'm driving. I live in the Midwest and the weather can change quickly, especially in the spring and summer. OnStar is about being safe in your vehicle. I can't think of any apps that they offer that are more important to safety than the weather app. Please bring it back! I will definitely pay a little extra to have the app. It's important to me and my safety! I called OnStar yesterday to let them know my concerns about this decision. I hope they decide to bring it back!On Star module broken
I ahve a 2023 Chevy Tahoe RST and the on star module has failed. There has been no connection since 8/31/24. The dealer has said it is on backorder and no ETA when a new part will arrive. Has anyone even had their on star module replaced if having similar issue? This is very concerning and upsetting as I pay for the subscription and have also paid an annual subscription for wifi that doesn't work. The clocks in my vehicle are all off and am not getting full functionality of the vehicle I paid top dollar for. The car wouldn't start a week ago because it was sending low voltage signals to every system because of the faulty module. Luckily the dealer got it operational again but said they can't just disconnect it because that would cause too many issues. Very very frustrated here....OnStar Module Broke
Brought my 2023 Yukon XL with 38K miles in to fix a recall and when I got it back now my “telematic control module/OnStar module” is broken and needs to be replaced. Dealer is telling me it will cost $900 and they have no idea when the part would even be in? This is ridiculous, not only should I not have to pay for this, but it shouldn’t have broke and if it needs fixing it should be done immediately.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?Onstar in my brand new 2025 Chevrolet Traverse LT is not working even though the light is green.
My OnStar stopped working 6 days ago! I called OnStar support since this is the 3rd time this happens! The first time they were able to trouble shoot the second time it fixed itself. Now this is the 3rd time and the OnStar button is green. I called and they told me the signal was not being received by my vehicle. They tried for over an hour. Even had me go into settings which didn’t work. Now they say I have to go to the dealership to see if they can figure it out! They said my unit might need to be replaced but how!! It’s a brand new vehicle got it with 3 miles on it!OnStar Telematics module - no dates for backorder part is unacceptable
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
