I used to love this app. Then it updated and now as soon as I log in it says to check out the new products and won't let me tap or look at anything. I'm extremely frustrated bc this was what I also used to schedule my oil changes and keep an eye on all of car's levels and give me a good notification without being in the vehicle to remember to schedule a service. Very frustrating!

When I tap on "My Vehicle", then "Vehicle status", Cannot get vehicle data in the app, (mileage, fuel level, tire pressure, diagnostic data, etc) error message: "unable to update, refresh or try again later, visit the help center for more support." 5/12 Still not working, even with the 4/15 update. Also wifi hotspot is not available, says it's enabled. Can edit SSID and password, but it ALWAYS reverts back to the original SSID and pw, no matter what I change it to.

Useless, jump through hoops to set up an account. Then the app will not recognize the account I just set up on the app... When it does act as if the thing is going to work, I'm met with an error message. Stating that it's unable to retrieve account details. I know my email is correct on the dealership, and paperwork end because I got an email suggesting this app.
