MyGMC Trailer Light Test
My GMC trailer light test functionality appears to have been removed or lost in the most recent update of the app - March 2025. I use this feature frequently. I called OnStar support today 3/9/2025 and they seemed confused regarding this trailer light testing feature. How do I get this trailer light test functionality restored in the app?448Views2likes20CommentsEV features removed from app
I have a 2015 Volt and myChevrolet app no longer shows EV detail on the app. This includes charging status, range, charging options, etc. Also, the "vehicle status" detail that is shown is from 16 months ago (Dec 2023). All of this functionality worked fine a few days ago. I loaded and reloaded the app on multiple devices and they are all the same.82Views0likes10Comments2025 Optiq not updating state of charge or anything when vehicle is off.
I have a 2025 Optiq. Vehicle is turned on, it will refresh the status of charge and other information. When the vehicle is off, however, it will not update 99% of the time. I have tried power cycling the vehicle like others have been told to do, uninstalling and reinstalling the app, trying the myChevy app instead of the myCadillac app. Nothing has been working. It doesnt seem like the remote start works either. If i try to refresh state of charge it tries for about 3 straight minutes then times out.32Views0likes1CommentMyChevrolet App Vehicle Status/Info Not Updating
My vehicle status, i.e. tire pressure, fuel level, miles, trip info, etc., has not updated in over 3 weeks. I've deleted/reinstalled the app, had a new signal sent, all of the things I've been recommended to try. None of these have worked. Please help!6.9KViews1like15CommentsRemote Start Option missing from my Chevrolet app - Samsung
The Remote Start Option missing from my Chevrolet app - Samsung S25 Ultra No longer shows as the option starting yesterday. It was an option if I long pressed the my Chevrolet app and as a Samsung routine. I have cleared data, cache, uninstalled and reinstalled the app. Still no fix.34Views0likes1CommentClimate control from app
I have a 2025 GMC 1500 Sierra Denial Ultimate and I not sure why I can not control climate controls from my app, I have installed the app updated the app signed back in and still no climate controls on the phone , I have read on here that it was taking off when Google was put in the software but I also read on here that GM fixed that and now it works but I cannot see it on my app so not sure what Im not doing right or what's happening and suggestions?

I recently purchased a 25 Chevy Equinox. However, I was surprised to find that the remote climate control feature—specifically the ability to set the interior temperature from the mobile app before starting the car—is no longer available. After contacting an OnStar advisor, I was informed that this feature has been removed for GM vehicles with Google Built-In. This is a handy feature, especially in extreme weather conditions, and was one of the reasons I purchased a GM vehicle. This change has negatively impacted the overall convenience and functionality of the app experience for me.Solved61Views0likes1Comment
