Previously supported Remote Start removed from MyChevy App
I have a 2016 Express Van equipped with remote start that I’ve owned since new. Whether it was the older OnStar app or the MyChevrolet app, remote start through the app (since it was an app feature) has worked for years. Recently the in-app Start button disappeared. When I called OnStar they said that my VIN doesn’t have remote start, despite it being equipped from the factory that way. My belief is that someone at either Chevy or OnStar made a change to the VIN reference feature tables. Since OnStar uses VIN tables to determine which features are enabled in the app, this effectively Nerfs a feature that was factory equipped. I have an appropriate plan, I have uninstalled/reinstalled the app, and did an OnStar vehicle update… so the problem isn’t the van or my plan. The problem is the feature list OnStar and the MyChevrolet app is referencing on their end.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.Not working...keep crashing
I've used the onstar guardian app for 3 yrs and never had a problem. Not it won't stay open, and when it does open it doesn't let you see your family members just the map. Nothing has changed and I've uninstalled and reinstalled. Any reason it isn't working now when it was working just fine? I'm using an android phone S25+Summary report of notifications
Where can I get summary of notifications from Onstar? Onstar is sending me notification whenever I drive eratic or slippery road, hard turn. Onstar notify me on my phone which is good but I need the summary report. I need it for investigation while my car was under repair at repair shop for 3 days im getting notified by onstar.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.
