I also reported the same issue with my Model 3 LR - since I took delivery in early Dec 2022, I've had to reboot the touchscreen for this exact issue 5 times (four times in the first four weeks, and the last time just today). I requested a service appointment after the fourth time two weeks ago, and they first set me up with a mobile appointment. But after asking for more details of the issue, they told me it was either an issue with the touchscreen or the cable to the touchscreen and said I would have to bring it in because they could not resolve with a mobile appointment. Then I had to wait 2 wks for the service appointment. So we'll see what they say when I finally am able to have them look at it.
