2016 Chevy Suburban LT Heated Seats failed. Need help!
Hello team! I got a 2016 Chevy Suburban LT I bought Late 2024 and I absolutely love it. My Family and kits love it as well but this past winter the heated seats shorted out. When it was super cold I put them on and they immediately turned off. Later on after it warmed up a little the rear seat pads work but the bottoms no longer work. Can I have help fixing this? I think it is the harness that is bad? Help?Mobile climate control
I have a 2025 GMC Sierra Denali and when o bought last year the mobile climate control worked until it disappeared. I’ve been on many frustrating phone calls, text thread, email you name it and I was given the unsatisfactory excuse that my Denali is not equipped for the service! I’ve been directed towards the dealer in which the dealer and GMC insists that the issue is with OnStar. It’s 11 months and I’m still paying for OnStar!!!!! This issue is disgusting and misleading.On Star display redundantly takes over my Driver Information Center (DIC).
We dont know what makes the Onstar Turn By Turn display that usually in on the larger Entertainment Center display to then also be displayed on my DIC display. The info I have setup to be displayed in the DIC is very important. Nothing we have tried permits us to close the Onstar data...only thing that works is for the vehicle to be shut off for a few minuets The Orstar data is still active on the larger Entertainment Center display so that is OK..but I cant have my DIC display displaying only On Star data redundantlyAlexa is gone from infotainment system and google store.
As many people have said in discussions for years now, No Alexa app, No customer. When I trade my 2025 Suburban in for a new vehicle, it will not be a Chevrolet. My entire house and business are connected through Alexa. Get with the program! Add features, don’t take things away that justify the purchase of a $89,000 vehicle. Your customer will leave you.Vehicle Status Issue
In the OnStar app, my vehicle will not show the status anymore. Says it was last connected 4 months ago, but my subscription is active, the OnStar light is green in the car, and I can still pull up the vehicle location on the map. I've tried logging out and logging back in multiple times, as well as uninstalling and reinstalling the app. I even did a call with support, and they said they couldn't see any issues on their end. Does anyone have a fix for this? My vehicle is a 2025 Chevy Tahoe RST. Thanks so much!!Months without OnStar Telematics
I bought a new 2026 Chevy Traverse less than a year ago. During my first year of ownership, the vehicle has spent 42 days in the shop after the ESC light tripped for the brake system. A few months later, now I'm now dealing with a failed Telematics module with no ETA for replacement parts. It's been 30 days since my dealership put in the order. My vehicle included a tech package with internet and OnStar service, neither of which work anymore. Remote start? Gone. Locate the vehicle via App? Gone. God help us if we're actually in an accident and need OnStar help. Can't connect. I'm losing value by the day with no end in sight. I cannot understand WHY replacement parts are not available for a new model. It's such a poor reflection on the GM brand.
