Is the OnStar Guardian app still working if I don’t see a notification on the app?

Once you’re logged into the Guardian app, it will remain active and functional until you log out, even if you close the app or when it’s running in the background.

If you don’t see notifications during your drive, you must enable notifications for the Guardian app in the system preferences on your device once the vehicle is parked.

If this action doesn’t resolve your concerns, please contact OnStar Technical Support at 1.877.558.8352. Please note that several device and app permissions are necessary for the Guardian app to properly function.
