Picked up my new Model S 100D last week. The delivery center took a little longer as they needed to download software updates which had a fix for the black screen issue. In any case the software version I drove out was 2018.10.6 b532133. After a week I had the valet park my car and turned on the valet feature (valet mode has important privacy features so thumbs up to Tesla). Upon returning the next day, I turned off the valet mode on my iOS app however the car screens were frozen in time (not black). The audio volume button on the screen worked but nothing else on the screen. I could engage the drive and reverse fine and drive the car. The car icon on the display had the doors appearing open even though they were closed, so clearly frozen in time! Fortunately, I was not far from the Tesla service center in Fremont. Service first tried the soft reset unsuccessfully. The hard reset (unplug the battery done only by the service center) worked - was in and out in less than 15 minutes. While I was waiting another customer drove in with a similar issue on his fairly new Tesla loaner car, he too turned on his valet and then subsequently had a frozen screen. By the way he said he uses the valet mode all the time on his own older Tesla without any issues so clearly this issue is probably for newer cars. Service advised me that I will get a firmware update when I get home. The update I did get was version 2018.18.12.5eadc71 (I am assuming you all have different versions so not sure this is helpful and may cause unnecessary anxiety like "when will I get to this version..."). Interestingly, the Release notes for the update did not say anything about the fix for the screen freeze. Did any others have this problem?
