Onstar stopped working
I'm writing to report an issue with my OnStar service in my 2022 GMC Yukon SLE. When my vehicle was parked, I attempted to locate it using the OnStar app, but the service wasn't working. Upon starting the engine, I noticed the OnStar green light was not illuminated inside the vehicle. When I contacted OnStar support, they suggested it might be a hardware issue. However, I've noticed this problem seems to be widespread. I kindly request that you investigate this matter further to resolve the issue. Thank you for your attention to this matter.Onstar Module Needs Replaced
I have a 2023 GMC Sierra 1500 Denali that I had to take in for a dealer for them to tell me the OnStar Module needed replaced. My vehicle is over the 36,000 miles so they quoted me close to $750 to fix it. This $80k truck is only a year and a half old! Mileage should have nothing to do with this part. How is this not something that is covered by GM and/or OnStar? Especially after reading about so many other brand new trucks having this issue.VIU - OnStar System Error code
Just got a brand new 2024 Chevy traverse a week and 1 day ago. Just hit almost 400 miles and a notification popped up on the dash that said “emergency services calling” and the Onstar light turned red. We pressed the button and the diagnostic report came back with error code B19DA. “The OnStar System is not performing as expected. An issue has been detected in the Wireless Communication System which provides security and safety features, turn by turn navigation, Wi-Fi, and much more. This may impact the ability for OnStar to assist in a crash and provide other services that you have requested.“ person on the phone said it’s an issue with the Onstar…not the vehicle itself? Anyone else have this issue?On 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 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.Telematics Module No ETA!!!
I have had my 2021 GMC Sierra AT4 at the dealer service station getting close to 3 weeks now. The Telematics module went out and there is still not ETA. I still have 3 months free of OnStar (could not turn it on due to the failure). This directly impacted key services like remote access, navigation, and emergency assistance, as we all some key items like engine power and ESC. According to the service tech, this failure not only compromises vehicle safety, but also debilitates any sort of diagnostics, that may severely impact mobility. Any insights on module availability or a suggested course of action would be greatly appreciated. The service staff at the dealer aren't helpful either, as they are in limbo when it comes to any communication from GM or OnStar according to them.Onstar Module failed 200miles into ownership
We just bought a brand new, 2025 GMC Yukon Denali Ultimate and this morning, a few hundred miles into ownership, the module failed. What a terrible experience. Six figure vehicle and we cannot use several features two days into ownership. Absolutely unacceptable. No supercruise, gps, internet, remote capabilities, nothing. We immediately called our gmc dealer and they placed the order for the telematics module but just like several other owners have experienced, its back ordered. Extremely frustrating experienceStreaming for RSE
Hello, just bought a new Yukon 2025, I have the streaming package but I can’t use the rear entertainment due to it saying that I need to purchase in vehicle streaming (which I have). I have been in the phone with OnStar multiple times, have had two “escalations” and reset everything under the sun 1,000 times. Need help.
