Currently on a road trip from the Toronto area to the Chicago area. Just as I arrived at my destination in the Chicago area yesterday, my 17" touchscreen became unresponsive to touch and there was an error message on the dash below the speedo that said something like "Touchscreen Error - Contact Tesla Service". I noticed that if I used the steering wheel controls to pause and play the audio that the pause/play icon on the screen would change -- so the screen wasn't frozen, I just couldn't make it do anything with my finger. So I tried re-booting and it came back to "life" working as before. Little worried about the trip home because you kinda do need the screen to be able to operate a lot of the car's functions. Should I be worried? Anyone else seen anything like this? One time glitch maybe?
