Supercruise stopped working, new Buick Enclave 2025
A new Buick Enclave sport Touring, 2025. Supercruise worked for 4 months, but then stopped. Now the icon turns green for 30 seconds, then turns red and disappears. Around 95% of the time it does not show the icon at all. Infrequently the speed limit does not show and sometimes the speed limit number is wrong. I called OnStar, they asked to press a few buttons and reset, then recommended to take to the dealership. The dealership reinstalled an update , but still not working. Then I called Onstar, who said they will escalate and look into it, but have not heard back any more. Is it a software issue? Can the tech support help? Or is there a hard reset/ factory reset option?
Wrong OnStar account in car!
I got my car a few months back, and I still cannot get the OnStar account working. It shows the previous owner's account info. It lists what I'm guessing is their phone number, no active plan, etc. I've called OnStar a few times, trying to get set up. I provided my info, got a confirmation email, gave them my credit card info (for when the complimentary service ends), etc. I'm going on a trip and want to use the WiFi hotspot. When I try to enable it, it tells me that I need an active plan. But I do have one. Going to OnStar -> Account shows the wrong information. When I contacted OnStar, they said they'd do a "remote reset". They had me turn the car on and off, leave the driver's side door open, etc. The computer still shows the wrong OnStar account. I tried leaving the car battery disconnected for over an hour. When I turned the car back on, the computer was reset to 12:00, but after a few minutes it seemed to download the wrong OnStar account info again. What are my options here? How do I reset the computer and get my OnStar account into it?Another Bad Telematics Module
I own a 2025 Chevrolet Equinox. My OnStar was spotty but working in March and April, but now went completely out. I called OnStar and they could not connect. They said it was probably the telematics module is bad and I needed to take it to the dealer. Took it to the dealer and after two days of trying to get the OnStar to work they said the module needed to be replaced. Fine, but the module is on back order with no ETA. I’ve read online that it could be up to a year. This is our only car and I pay a lot for my subscription. I do so because OnStar is something I rely on and now you tell me I’m without it for weeks, months… who knows? Plus I’m spending $$$ for nothing until it’s fixed. Someone surely has an idea of when I can get this fixed…don’t they?OnStar Button/Super Cruise
My OnStar Button in my 2025 Chevy traverse is not working. I have tried to push it and talk with someone, however, nothing happens. No static, no beep, nothing. Also, my Super Cruise is no longer working. When I push the button to engage the Super Cruise, message pops up saying "no road information available." However, its the same roads I have been traveling since I bought the traverse.2024 trax
We have had this car over a month and the WiFi and hotspot has always been grayed out. Spoke with OnStar at least 10 times and raised to level 3 techs multiple times. I have brought it back to the dealer and still no change. This is my last ditch effort for help. Bought so with can you her computer for work with hot spot availability and yet has never been able to use it!Telematic Control Module Failure - No "Get Well Plan" from GM Corp and the CEO of GM, Mary Barra.
To the GM Executive Customer Care and Corporate Leadership and to my fellow GM product owners: I am formally escalating a serious and unresolved issue regarding a Telematics Control Module (TCM) failure on my 2025 GMC Acadia Elevation, purchased in October 2025. My authorized GMC dealership has confirmed that the vehicle’s TCM requires replacement. Based on discussions with dealership personnel and extensive owner reports, this failure appears to be systemic across multiple GM platforms and model years, not an isolated incident. Despite widespread awareness of recurring TCM failures, GM continues to: Sell vehicles equipped with these modules Market and charge customers for OnStar services that may be partially or fully non‑functional Leave dealerships without sufficient replacement modules or clear remediation guidance This raises serious concerns regarding customer safety, transparency, and corporate accountability. Key Issues Requiring Executive Review Paid Services & Disclosure Why does GM continue selling OnStar subscriptions on vehicles known to suffer TCM failures that compromise emergency, location, and monitoring services? Why are customers not clearly informed of these known risks at the point of sale? Manufacturing & Parts Strategy Are newly produced GM vehicles equipped with updated or redesigned telematics modules, or are the same failure-prone units still being installed? If improved modules exist, why has GM not prioritized distributing them to dealerships to repair affected customer vehicles? Safety & Liability Exposure What safety systems are impacted when the TCM fails—specifically emergency response, airbag crash detection, vehicle tracking, and occupant monitoring? How does GM mitigate the risk of delayed or failed emergency response in accidents involving vehicles with known TCM failures? Corporate Oversight & Trust Why has GM not issued a formal service campaign, recall, or goodwill repair initiative to address this issue? How does GM intend to preserve brand trust while allowing a known electronic safety-related failure to persist? Broader Risk Implications Given GM Defense’s role as a supplier to the U.S. Department of Defense, unresolved systemic quality issues in consumer vehicles raise legitimate concerns about component reliability, governance, and risk discipline across the enterprise. Expected Resolution I am requesting executive-level intervention to provide: A clear acknowledgment of the systemic TCM issue Confirmation of whether redesigned replacement modules exist Immediate corrective action for affected customers Reimbursement or suspension of OnStar charges during periods of non-functionality A defined remediation or “get‑well” plan communicated to dealerships and customers This issue is solvable, comparatively low-cost relative to major powertrain or structural problems, and represents an opportunity for GM leadership to demonstrate accountability and customer commitment. I respectfully request a written response from GM Executive Customer Care or Corporate Leadership outlining next steps within a reasonable timeframe. Thank you in advance for reading and responding to my posting/message.LINE OPCODE TECH TYPE HOURS
