Before you take it for service try this:I have lost almost all screen function with the new update. (2018.48)
See images of how it looks.
Did update Friday night, screen was messed like that most of the weekend after the update. At times it will flicker back to on with horrible graphics, but then go right back to the colored lines. Never had this issue before the Friday night update. And it has never flickered back on since, aside from last night...
After charging last night (Sunday night), the screen was fine when I got in the car, but a mile into my drive, right back to colored lines. Reboots don't fix (can't do the re-boot via the screen, only two scroll wheels)
I did get the message that the Update Completed successfully, so I'm hoping they can just roll me back to the old update to fix this, as I don't think it's an issue with the update not fully finishing.
I guess the screen could have just gone out coincidentally.
Next service appointment is Jan 9th which is crazy because I don't want to go over a month with no MPH, no Back up Camera, no Proximity Chimes when parking (turned those off the day before so the baby wouldn't wake up while parking), No Sound/Music (it's frozen on something and the left scroll wheel don't start any music), No Navigate on Auto Pilot to work, etc. (first world problems)
If anyone has experienced this, please let me know. Waiting for a call back from Tesla now.
(Update: they say, sorry, soonest is over a month away, tough luck. This bothers me a little, but i do understand somewhat)
There is an option in the menu to power off the car, let the screen turn off for 2 mins then press on the breaks to turn it on. If that doesn’t work try soft reset by pressing the two buttons in steering wheel, hold it until the screen turns off and shows the Tesla sign.
Let us know if any of these resolve your issues.
In an extreme case, there is an option for factory reset.
