20 TopicsClimate Control Feature - 2025 GMC Sierra 1500
Hey everyone, Looking to see if anyone else is running into this. I have a 2025 GMC Sierra, and for the past few months my myGMC app no longer shows the climate control option. I used to be able to pre-heat/cool the truck remotely with no issues, and then the feature just disappeared one day. It hasn’t come back since. I contacted OnStar online support, but they weren’t any help—they just gave generic troubleshooting steps that didn’t fix anything. Has anyone else had this happen? Did you find a workaround or get it restored somehow? Appreciate any insight.54Views0likes1CommentMy 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.241Views1like5CommentsApp controls keep failing
A bit frusterated as a bought a 2022 Yukon Denali with 36000 miles less than three weeks ago. I have had nothing but problems and countless phone calls with onstar. Have tried endless amount of troubleshooting and finally referred to dealership. None of the control functions (remote start, lock, unlock, etc) will work on my app. They will continue to spin and then fail. Very disappointed as the vehicle is not old and low miles, as well as I just got the vehicle. The vehicle stats (gas, oil life, etc) will not update either. Anyone else have this issue?91Views0likes1CommentMyGMC app not updating vehicle status since OnStar had to refresh my wifi signal a week ago.
I have a 2024 Sierra 1500 and my vehicle status has not changed since OnStar had to refresh my wifi signal in my truck 7 days ago. I don't know if there are any similarities but the vehicle stopped updating after the refresh. I have already done the power cycle of the truck (run for 2 minutes...off for at least 2 min...sign out of the MyGMC app and back in...have also uninstalled and reinstalled several times). I also have another vehicle in the app and it is updating just fine. The link seems to be the truck but not sure.15KViews7likes79CommentsRemote climate control still missing
I have a 2025 Sierra Elevation. When I got it in April, remote temperature control was available in the app. Now it's gone. I have had a ticket 68838346 open with support since 6/17. After gathering information via email, I was told a support engineer would be in touch via phone. I have heard crickets since. I have followed up via email several times with no response. Can I get some help here please?319Views1like6CommentsMobile app- vehicle status
MyGMC app will not update vehicle status. I've tried uninstalling, log out/back in, granted all app permissions, clear cache, restart phone, Still nothing. Seems to happen about 2 months ago with the update at that time. Since then nothing seems to reconnect the vehicle. All other controls work. How do I reconnect this vehicle status part of the app?175Views0likes5CommentsMy GMC app isn't working after last update 18/2/2025
My GMC app isn't working after last update 18/2/2025, so after you open the app the sign in shows up and i put on my credentials and then the app keep loading for ever and never complete or open. So i had to use the other app My Chevrolet app and that works fine and i can access my cars through it. so am wondering what is the issue i tried everything such as restarting my phone, close all apps and un-install "My GMC app" and re-install it and still same issue.689Views2likes3CommentsComplete Scam
So I bought a new to me 2024 GMC Sierra HD Ultimate. It was original sold with 3 years of connected service (I have the window sticker) Called Onstar yesterday to register it to me. The rep gave me a year of the premium plan. Sweet! Not so fast. Everything worked for about 2 hours. I called in today to see what gives and the rep tells me they did away with the old plan that I have just been given a year of, and if I want connectivity it's 57 bucks a month! wtf?! So GM charged the original owner at purchase. And then under the guise of a "new plan" they want to scheme me for 57 bucks a month. On a truck with 100k+ msrp no less. Complete joke!177Views0likes1CommentMyGMC App Nearly Useless on New Hummer
Such a disappointment. I traded my BMW x6 for a 2025 Hummer EV 3x. I never thought the App experience on an EV would be so poor. Nothing refreshes unless you log out/in. Went through an hour of troubleshooting with App Support, and after nothing worked they said “something must be going on with the system since a lot of people have been calling with the same complaint”. It looks like this problem has been happening for MANY owners for years. I can’t see when the car is charging, it’s progress, I can’t set a location, everything is painfully slow and it doesn’t matter if I wait days!! The manual refresh button doesn’t work and I have to walk out to the truck to see how it’s doing. The whole Google/Android interface is painfully slow in the vehicle. Doesn’t feel like a 100k+ experience and I’m having serious buyers remorse coming from BMW and Mercedes. I don’t think I’ll ever buy a GMC again when I’m done with this one.940Views2likes2Comments
