Chevy app commands not working
My Chevy app commands do not work. I have a 2026 Chevy Traverse LT. I have live chatted customer service and have done all the necessary reinstallation’s and deletions. I have done any sort of trouble shooting they have told me to do and nothing. I have even called and still nothing. Every time I try to send a command it takes a while to send then ultimately fails and says “Failed to reach traverse”. It has been happening ever since the purchase of the vehicle.

Location notifications not working
I am no longer receiving location services alerts on my Chevrolet app. This was working and it has since stopped. I followed steps to troubleshoot and tried uninstalling and reinstalling and nothing. Everything else in the app seems to be working and I can see car location, but won’t notify me.

Remote Options Disappeared from App
I got a new iPhone Max Pro and when the app refreshed, the start stop options were gone. I have a 2024 and I’ve owned it a little over a year. I’ve uninstalled the app and reinstalled and it still doesn’t show.

Remote climate start often fails in '26 Lyriq
When I use the myCadillac app to try to remote start climate in my car, it usually fails. Other actions often take forever and fail, too. The dealer has looked at it and said to contact OnStar. I previously had a '24 Lyriq and it had the same problems - unreliability of remote actions. It doesn't seem to matter if the car is connected to my home WiFi or if I'm away from that. Pretty frustrating to not be able to come back to a warm car in our frigid Midwest winters despite having purchased a luxury car. I've been through several support tickets and basically lost faith that GM knows what it's doing.

App is not updating
My app hasn’t updated for 2 days now. It hasn’t changed the fuel level, miles, and tire pressure levels. Only thing working is my remote start and locking and unlocking of doors. I have already restarted my phone, uninstalled the app and reinstalled it, logged out and logged in, checked to see if my phone needed an update, and checked to make sure my onstar account was still active. What is going wrong with the app connecting to my vehicle????

App hasn’t connected in over a month
My app will not connected to my 2025 Silverado. Can’t see diagnostics, can’t remote start. Pretty much useless. I’ve done everything they say to reset it but nothing works. Extremely disappointed

MyBuick app
Both MyBuick and myGMC apps have lost connection to both vehicles and I have no controls. Is this an app issue or an issue with my vehicles?
