    Horrible app and even more horrible customer support. Linking to your Onstar is ridiculously difficult. The sign in process feels like 1999.

    Using the remote fob works half the time. Won't update the vehicle status. If it's a known issue, why haven't they done anything to fix it yet? The app is broke!
