It used to work, doesn’t now.
I did have the app on an older phone (phone crashed), and it did work. It was nice to use to find what maintenance was due, and I think, the dealer would update it, similar to what a new car dealer does with your vehicle maintenance records. Now, I have a newer phone, thought I would try download the app and try to login. I get an error message. If I try to use the recover password and it does nothing. If I try to register again, it’s stuck in an infinite loop.
