My GMC app.
Has anybody actually had their OnStar app work right after they’ve contacted OnStar about the issues with the app. I’ve owned a truck for over a year and it hasn’t worked right since day one. I’ve contacted OnStar no less than six times and every time they run a diagnostic, it’ll work for two days or less and then you just get tired of it,as of right now my app has been down for 25 days again and I’m just kind of giving up on it. It is a good app when it works. It just doesn’t never work.15Views0likes0Comments- Driftincowgyrl4 days agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor17Views0likes0Comments
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.4.9KViews7likes15Comments- Angieblazer4 days agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor85Views0likes4Comments
CarPlay inoperable with new iPhone 17 Pro and Pro MAX
I have a 2020 GMC Sierra 2500 AT4 with the dramax. I just purchased a brand new iPhone 17 pro a week and a half ago. Since day one when I plug the phone into the USB-C and the USB-A port the phone charges and connects to Apple CarPlay like normal. However after approximately 5-7 minutes the phone disconnects from CarPlay but stays charging. I have tried all ports in the vehicle to include the ones in the center console. All have the same issue. I disconnect the cord and replicate it in and it connects to CarPlay again then quickly disconnects. Yes I am using apple cords, 3 different ones from the Apple Store, and have also tried an aftermarket Anker cord as well (40watts which is what the iPhone requires) I am coming from an iPhone 14 Pro Max and it worked without issues. My wife’s iPhone 14 Pro Max still works without all ports plugged in without issues. My work phone (iPhone 12) works with CarPlay without issues in all ports as well. I have contacted Apple support and send them numerous screenshots and screenshots recordings of the issue and they do not know what’s going on. I have tried the new phone (iPhone 17 Pro) in my wife’s 2021 Subaru Ascent and it works no problem. I truly believe this is just a simple update from GMC or OnStar (whoever is responsible for updating the infotainment center). I have already checked for updates and my truck is currently up to date. Can someone please shed some light on this. Thank you for the help.1.5KViews0likes12Comments2025 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.Dangerous335 days agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor II447Views0likes10Comments2025 Buick Enclave - Ongoing OnStar / Battery Drain Issue
Hi everyone, I’m posting to see if anyone else has been dealing with the same issue. I have a 2025 Buick Enclave that I purchased brand new about nine months ago. From the start, I’ve had recurring problems with the OnStar system and a total loss of power. The vehicle has repeatedly gone dead or failed to start. The dealer told me it’s related to a defective OnStar (telematics) module that’s been draining the battery and preventing the system from going into sleep mode. My Enclave has now spent over 30 days in the shop, and we’ve had a case open with GM for weeks — but there still isn’t a confirmed fix or part available. We have been enduring these issues while our brand new Enclave sits in the shop, and we have not received answers (from Buick or the dealer) for how it will be resolved. I wanted to share this in case other owners are experiencing similar problems or have received any updates or resolutions from GM. If anyone from Buick or GMC sees this, please reach out — I’d really like to get this resolved.scjenisland5 days agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor82Views0likes5CommentsOnstar light red 2024 Trax RS
I’ve been to a Chevy dealer 8 times in the last 2 months. I’ve had my radio replaced. Everything reprogrammed and now the Onstar module was replaced 2 days ago. Today I’m having the problem again. It’s more consistent now. No wifi. What am I paying this monthly fee for?KingSteve2156 days agoPlace Technical and Service SupportTechnical and Service SupportNew Contributor27Views0likes1CommentOnStar Module Failure - software recall?
My 2022 Chevy Suburban Z71 OnStar Telematics Module likely failed. I took it into a local dealership in January due to the software recall. I explained to the service department that I had not been able to use the App to access vehicle info, start it remotely, access wifi, etc... since Nov 29, 2024. The service tech told me that the new software update should fix the problem. I had read about the telematics problem and called the service department prior to bringing my car in and the mechanic explained he would take a look at it. When the car was ready, I tried to access use the app and it still did not connect. The tech told me that I likely had to give the software some time to work itself out:). I'm in software and knew this was a load of BS. I asked him to bring the car back into the mechanic and he said I had to make another appointment and come back. So, my question is, what about the lack of access and I am still paying for wifi and OnStar. Can any credit be given retroactively and cancel or put this on hold until the issue is resolved? I am paying for something that is not functional....1.7KViews2likes17Comments
