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.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 travelOn 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 - 2022 Cadillac Escadale ESV
I bought a 2022 Escalade, and the OnStar Telematics Module is not working. I contacted OnStar, and after a few unsuccessful tests, they told me to take my car to a dealership to have it fixed. However, even though Massey Cadillac in Orlando confirmed the OnStar module needs to be replaced, they keep saying the part is on back order and they have no ETA. I am very unhappy with this situation and do not have a solution offered by OnStar or Cadillac. My car is still under warranty and Cadillac or OnStar must be responsible for it. I am afraid I will need to take legal action to have this part replaced.On-Star Telmetric Module Failed
I bought my 2023 Chevy Tahoe brand new in 2022. On-star Module Failed a week ago. Dealership said my extended warranty did not cover it. Part is back-ordered with no ETA. They made me pay for the part before they'd even order it. From what I've read this is a widespread problem that chevy and on-star have known about. I very angry because the whole reason I bought this car was for the entertainment package that no longer works. From also what I've read it could be months before it comes in if it comes in at all. Something needs to be done.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 happening2025 GMC Yukon
Bought my Yukon May 5 2025 brand new less than 25 miles and On star doesn’t work talked to the dealership today and have to make an appointment to have it looked at to see what the problem is. Having problems with the apps and and clock doesn’t work nor does the navigation. Green light is on but get no response from On star. When you pay 80,000 dollars for a vehicle and it relies on a service to make it run is unacceptable. I owned a 2016 Tahoe with no issues or problems. And On star worked. I’m starting to think I may have made a mistake purchasing this vehicle. If the problem can’t be fixed in a timely manner I will ask to be refunded and purchase a different brand. Again this is unacceptable ON A BRAND NEW VEHICLE. GM needs to address the problem and admit that there is a problem and fix the problem.Urgent Call for Action to Address Chronic OnStar Wi-Fi No/Slow Internet On (2015-2025) Wifi Hotspot)
I have a 2016 Chevy Suburban LT with OnStar Unlimited Data Add-On. I see rampant complaints online regarding the OnStar Hotspot Services and have an equally treacherous user experience with OnStar Hotspot Unlimited Data Service compared to my AT&T Google Pixel 9 Pro XL on the road when verifying that on speed tests sitting idle at any given location I suffer non-connectivity or slow and or limited connectivity to internet data. I can assure any who read this the issue is exclusively MVNO related as many tests I have done conclude zero issues with a device connecting to the hotspot itself. The Internet gateway aka router built in works and has worked flawlessly. It's the lack of data being sent and or served from the carrier to the device. The vehicles are the device and the hotspot is under data cap restrictions causing all of the grief and heartburn millions of customers are suffering from. As a loyal OnStar customer, I am urgently calling for immediate executive intervention to address widespread issues with the Wi-Fi hotspot feature on my 2016 Chevy Suburban. I am part of a vast community of OnStar users who have been grappling with poor connectivity and speed constraints that, despite loyal usage, remain unresolved. This issue is not just about intermittent connectivity but a systemic problem rooted in the technical design of the service. Without prompt action from OnStar and GM leadership, millions of users will continue to face crippling limitations, potentially leading to serious legal implications due to unmet service expectations and lack of transparency in the advertised "unlimited" data plans. Upon activating my OnStar hotspot, I noticed critical limitations that severely hinder real-world use. Despite my extensive experience in tech support, which spans over 36 years, I struggled to understand why I was seeing drastically reduced speeds—1 Mbps download and 0.5 Mbps upload—compared to the typical high speeds I experience with AT&T cellular data on my phone. This indicates a possible built-in throttle within the hotspot, impacting every OnStar customer using these services. Despite troubleshooting and calls to OnStar support, I learned that my usage appeared capped without sufficient transparency on these limits. This issue appears to stem from the way OnStar is handling its Mobile Virtual Network Operator (MVNO) relationship with AT&T, wherein hotspot speeds are restrained far below what is advertised or expected. Customers have a right to know that the “unlimited” plan they pay for comes with significant caps, effectively nullifying its practicality for any substantial usage. This discrepancy in service needs to be addressed immediately, both for the integrity of GM and OnStar as trustworthy brands and to avoid the risk of legal consequences due to misrepresentation of service capabilities. To address the root cause of this issue, I implore OnStar and GM executives to renegotiate their data plan structure with AT&T. It is clear that users are facing artificial caps and throttling due to restrictions imposed at the MVNO level—restrictions which should be made transparent and, ideally, removed for customers who are willing to pay for true high-speed, unlimited data. The request is simple: allow customers to pay for a genuinely unlimited hotspot option. Just as other wireless carriers have modified their offerings, OnStar must offer a tiered data structure that allows for true, unrestricted hotspot use—one that aligns with the advertised benefits and meets the high standards that GM customers expect from their vehicles. If this issue remains unresolved, OnStar risks facing class-action litigation from a growing community of frustrated users, compounded by potential regulatory scrutiny for misrepresentation. Customers deserve clear, honest communication about data limits and options for real-world performance that meets expectations. Transparency will not only protect OnStar from legal consequences but also restore trust in the service. This is a critical moment for OnStar and GM to demonstrate a commitment to customer satisfaction and innovation by delivering the connectivity that modern drivers expect. The opportunity is now for OnStar to lead the industry by providing a viable, consistent, and genuinely unlimited data solution for its customers. I urge you to act swiftly in addressing this issue at the executive level to avoid further dissatisfaction, negative publicity, and potential legal fallout. Thank you for your attention to this matter and for taking the necessary steps to ensure a solution that will benefit millions of loyal OnStar users.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.
