Service Driver Assist System
I have a brand new 2025 GMC Sierra Denali Ultimate 6.2L. When I reached 1k miles, the service driver assist system started popping up on my dashboard. I’ve been to the dealer twice about this issue. The first visit, they informed me they couldn’t do anything because no codes were coming up on their reader. It kept happening and then said something about the front camera blocked. The second visit to the dealer, they installed a new camera and the next day the same issue continued to pop up on my dashboard about servicing driver assist system. I spent too much money on this vehicle as I’m trying to give them the opportunity to do the right thing because I’m not gonna keep paying on this vehicle and dealing with these issues. This should not be happeningDannyboi3 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor II257Views0likes5CommentsOnStar 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.jmarinelli003 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor1.5KViews4likes24Commentsclass action lawsuit OnStar module backorder
Time to hold GM responsible for the no ETA on Onstar Module. Attach your name to be added.chauser9 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor II577Views8likes15CommentsWiFi Hotspot, No Connection to Internet
I have a 2022 Chevy Silverado, bought the thing used awhile back. The WiFi Hotspot has never worked, basically it will allow a device to join but does not actually route to the internet. I have had several other Chevy/GMC trucks where the WiFi/Onstar stuff worked fine, so I know it's possible. I have called onstar several times, today for the forth time to work out this problem. It is always exactly the same thing. Forget the network, leave the truck with the door open for a few minutes, jump through some other hoops. It always ends with, we have to open a ticket for their other support guys and they will call me back to let me know when the problem is fixed. Crickets... NEVER a call back, we have confirmed the call back number every time. From the customer service perspective this is pretty disgusting, make a commitment to a customer and fail to follow up on a service that has been paid for but non-operable. Every time the phone support guys focus on the toggle switch for "Share Hotspot Data" and the fact that it's impossible to toggle on, I'll attach a picture if the forum permits. Anyone know what that does or why it is there? The owners manual says nothing about this toggle. Maybe it's the problem but it makes no sense. Why would anyone want to toggle the ability to route to the Internet (or any other network) if you have already allowed the WiFi connection? Why would you connect in the first place if you didn't intend to go somewhere? Anyway, other network based apps work OK, Pandora, MyGMC, Weather, etc. Some kind of data routing is happening somehow, just not on WiFi. Anyone have any idea how to get WiFi routing to the net? Anyone know what the definition of this toggle switch is? Anyone know how to get past the first line guys and talk to someone who knows something?dilburrito10 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor154KViews9likes36Comments2025 Blazer EV: Telematics Failure, No ETA, and No OTA Updates — What’s Going On at GM?
As an early buyer of the 2025 Chevy Blazer EV, I had high hopes. I believed in GM’s vision for the future of electric vehicles. But my ownership experience has been marred by ongoing support issues that I feel compelled to share for the benefit of other EV owners and prospective buyers. Shortly after taking delivery, I discovered that I couldn’t access Tesla’s Supercharger network—something GM advertised as a key convenience—because the required adapter wasn’t available. Even GM itself couldn’t source it for weeks. Eventually, I received one, but only after significant inconvenience and lost travel flexibility. More troubling is the issue I face today: a failed Telematics Control Module, which has disabled my OnStar system and cut off access to over-the-air (OTA) updates. That means my Blazer may not receive important software improvements or even safety-related patches unless I manually bring it into a dealership—something I was told would be handled automatically when I purchased the vehicle. There’s no ETA on the part. The dealership, sympathetic as they are, admitted that many GM parts are backordered and hard to obtain. They even encouraged me and others to reach out to GM directly—something I’ve now done repeatedly. Through it all, my Senior Executive Resolution Liaison, Amira, has been incredibly helpful. She responds promptly, remains professional, and has shown genuine concern for resolving the issue. But even she is hitting brick walls. I truly don’t know how she does her job every day without the tools she needs. Frankly, GM should be paying people like her double. I’ve tried to handle this privately and with patience, but I want to raise awareness among prospective buyers and encourage greater transparency from GM.Dangerous3310 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor54Views0likes3Comments- 12Views0likes2Comments
WiFi Hotspot - No Internet
I have a 2025 Tahoe with a OnStar One Super Cruise Plan with Connected Plus Unlimited Data Plan. My head unit and Rear Seat Entertainment all have data. However, when you connect a phone or tablet to the in-vehicle hot spot I get no data. The connected devices complain there is no Internet on the hot spot. Any ideas? I have seen similar complaints on Reddit for these 2025 GM vehicles.JWPappas13 hours agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor II468Views2likes17Comments2025 chevy malibu rs not getting updates on mychevy app

I recently bought 2025 Chevy EV Equinox and my GPS stopped working. Nothing works cannot call onstar, no connectivity cannot plan routes or find charging locations. It was hard to take it to dealership since no one wants to look at these kind of issues. Now they say that the onstar module needs to be replaced and it’s been back ordered. First time buying a GM vehicle and probably would be the last time. Dealers dont care and say it might even take longer and my lease might end before part arrives.15Views0likes0CommentsOnstar telematic communication module Defective.
My brand new 2025 Silverado EV has been sitting at the dealership for close to a Month now. I need someone to give me my money back for an 80k truck I can’t use. We definitely need a class action lawsuit for this shenanigans. Obviously R&D seems to sucks at this company.86Views0likes4Comments
