2014 Model P85D, warranty ran out in December 2018. My main, large , display would not come on so I called Tesla service. They are impossible to get a hold of and my app would not work since it could not connect to the car. I called and waited 45 minutes for Tesla to answer, they told me it had "fatal errors" so bring it in.
Turns out I had what they referred to as "corruption" in the computer and they could not connect to the display , they replace the entire screen and computer for $2,800.00
I had the screen give me trouble booting up a few times over the last year so I think I started having the problem while under warranty (they said I did have fatal errors preciously but the computer was able to correct them) but unfortunately it did not totally fail till after the warranty.
Anyone else having this problem , that is a very expensive repair .
