Car does not respond to phone app. - the app screen has a white background stripe at the bottom with the message "Updated on Dec 65,2019" On Rt. side of the stripe is a circular arrow that just goes round and round. When it finally stops, there appears on the left side of this strip a black triangle with an exclamation point in it.
Entering the car, the screen is dead - nothing!
Battery is about 50% charge.
The dashboard has a message that car is starting up. After a few minutes, that message goes off, the dashboard remains illuminated, but nothing works. I can put the car in gear and drive it, but I cannot even unfold the mirrors. Pushing both steering wheel nobs, with or without foot on the brake, does nothing.
Note the car is 2 years old, so I consider myself reasonably competent with the controls. I'm stumped. Any suggestions?
