So I took delivery of my car on June 20 and the same day the screen went frozen while I’m driving for once. After the following 2 weeks, it happened 5 times. The last 3 times even got scarier, the screen went totally frozen and the fan just turned up to the max automatically, almost making me freeze. The glitch happened both when I’m still on the 2021.3 ish software version and latest version 2021.4.18.10. I already had my service scheduled for tomorrow, but I figured I would be nice to ask around in the forum first just to get a rough sense.

It could be as "simple" as a corrupted software install, or it could be something more serious. I had similar happen to my car (right after delivery as well), and they had to replace the MCU.

I highly doubt my case is also about MCU. How long does it take for them to replace the MCU though?

I hope so too. At the peak of the issue, my screen would keep crashing and going dark every couple of minutes. It even happened while I had Autosteer enabled on the freeway once. Of course, the car was still controllable and exterior lights functioned, albeit silently.

It took them a full day to swap mine out.
