The app has come a long way since I started leasing my car in Oct 24 and I find it to be fairly reliable and easy to use. It's just missing a few features that could make it a solid 5 in my opinion- home screen widgets, bring back the vehicle update history/notifications when new updates are available, and show us the locked/unlocked status. other than that, does what it needs to do in a fairly quick and painless manner.

Extremely unreliable. It costs so much extra money each month for remote commands, but I don't know why I bother when it fails more often than not anyway. The app is slow regardless of the phone's performance - I've uninstalled, reinstalled, cleared caches, rebooted, you name it. It still sucks and I just need to accept that the fob is way more reliable, though it has very limited range.

Actually, the app works quite well and has significantly improved in the few months I've owned the car. But I'm giving it a low rating because it's pushing advertisements / special offer notifications at me which I can't disable without also disabling important charging-related notifications. Stop pinging me with special offers and I'll consider a better rating. UPDATE: increased rating since it hasn't pushed any special offer notifications in several months.
