Useless. We pay a monthly service for this app and it hardly ever works. No mention of any updates (assuming that is why it's not working)and when you truly need it..pre-start your car in cold weather, tracking your vehicle etc. It never works! Would not complain if it was still free, but since you want to charge..upgrade the experience. Thank you.

Most annoying thing is the persistent notification about the "Trusted Device" service being active. As far as I can tell this does nothing and there is no way to turn the notification off other than to block all notifications from the app which I'd really like to not have to do for fear of missing an important one. Also, the app is super slow to update the charging status of the car and the map only loads half the time (even on a strong WiFi signal). Very disappointed in GM's software team.

I rarely leave comments, but this app/car communication is so bad that I'm compelled to leave a comment. I don't know if it's the car or the app, but they don't like each other. I wish I could leave (-)negative stars. Trying to start my car before leaving work in 25 degrees would feel amazing if the app actually started the car, but it fails more often than it works. It takes way too long for the car to update the app. My level of disappointment is about as high as the cost of the car.
