Just bought a used 2017 Model X. Everything was fine for a couple days until the screen froze up. Tried rebooting with the scroll wheels but those no longer work as well and the horn stopped working. To make it worse, since its still in the process of being registered in my name which DMV says can take up to two weeks. I can't do a ownership claim so I am unable to get a ranger to take a look at it as I am unable to use the app. The car is pretty much undrive-able. Help!
