Horrible app! Should be free! Can NEVER use it to schedule maintenance. Selected schedule service, type of service, select dealership, advisor, method of service, appointment date & time, (the contact info is already pre-installed) and that's it, you can't hit continue, the button stays a shaded gray, as if more info is needed but their is nothing else on the page required. The app could be helpful on wknds, after-hours, shop busy, closed or when you busy it can be quicker, to do in app.

This app used to be great, but since the update, I can barely use it. While I don't love the change to entering your full password every time you sign in, I can deal. It is the fact that I can no longer start my car with it. Just tells me it fails and then locks me out of my car. The locking mechanism just stops reading for about 3 to 4 hours. Can't even use my door locks, nothing reads. I have to uninstall the app to get in. Paying to not be able to use.

Recently, the app gets hung up all the time. I've uninstalled/reinstalled it, forced closed it through, and searched for updates. the start function gets stuck on sending, but doesn't start. i have to send a different command (lock), just so the sending won't display. I'm terrified it'll start eventually at a really inconvenient time. sucks that it happened while it was cold. i miss the warm seats
