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.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 travelService 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 happeningNone of my Driver Assist features work on my brand new 2024 GMC Denali pick up
None of my electronic Driver Assist safety features work on my brand new 2024 GMC Denali pick up. These safety features were a major selling point in my decision to purchase this vehicle. I have brought the vehicle back to the dealer several times to have the problem fixed. Finally, I was told that the replacement module needed is not currently available , and that there is no known date for the part to be delivered. It has been three months since the problem began. How many other car and truck owners are experiencing this issue and what is being done by GMC to resolve this problem ?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.2025 Suburban - Wifi Hotspot doesn't work
Just bought a 2025 Suburban in February. The Wifi hotspot initially worked but now that my trial has ended and I am just running unlimited data it won't let any devices connect. I contacted support through and they tried multiple times to fix it but have now submitted a ticket to technical support because they couldn't get it to work. Considering the car is only a month old and my previous Chevy never had issues with the hotspot this is very frustrating. Anyone figure out what the issue is? Don't really want to wait 5+ days for support to reach back out.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.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 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.
