I’m pretty sure the computer that runs the convenience systems (displays, climate, audio, etc) is a completely different computer than the one that actually operates the car (motors, stealing, autopilot, etc). Rebooting one has nothing to do with the other, and presumably the software the runs the actual car is rock solid and doesn’t need rebooting to resolve bugs like the convenience computer does.

Tesla stated that the car has two separate computer systems, one that handles media/screen/sound and one that does everything else. So we have two levels of reboot: rebooting just the media/entertainment system, which evidently can be done while under way (not that anyone would really want to do that, I hope) and rebooting the much larger system responsible for everything, which can only be done in parked state. doors closed, foot on the brake. (You can also reboot everything by turning the car off on the screen menu.)

Bernard you are correct on the computers. This is why you can reboot the "Display\Convenience" system without issue while driving. Earlier on in the firmware versions (I have 2xxx vin) there were issues display related and others that required reboot. Since the late teen and twenty versions I have only had to reboot once or twice.

I've reset my MCU a few times while driving. Had phantom touches in the screen that would mess up the podcasts I was listening to and didn't want to pull over to reset. So I set my cruise control and rebooted.

Phantom touched have happened a few times in the 8000 miles I've driven and rebooting fixed them.

I kinda think that holding the brake pedal has no effect during reboot, and that to do a more full reboot you needed to use the Power Off feature in the UI (Controls > Safety & Security > Vehicle Power > Power Off).

My display keeps rebooting on its own. Sometimes it will do it 3 times in 5 minutes, other times I go an hour of driving and it does nothing. Not making sense, not sure what to do?

I would call Tesla roadside and ask if they think reloading the last update would help. Or maybe they can see error codes that are being thrown in the logs.

How do I call Tesla roadside???

This is unbelievable. Happens so much. I am absolutely blown away by this and it’s ruining my Tesla experience. For an $80k car I feel like I am getting a “software lemon”. Drives great. Looks great. Software is absolutely TRASH.

They gave you a little card, which you probably put in your glove box.

1-877-798-3752

The software is pretty awesome.

Something is wrong with your car. Sounds like maybe a loose connector, or a crimp-short.

Tesla should be able to trace the fault, perhaps remotely.

I agree something is wrong . I have never had my MCU restart on me randomly. I'd call service right away. I'm going to guess you will end up with a new MCU.

I managed to lockup the screen today, my granddaughter wanted to load the atari game console, that was enough to kill the display.

Didn't realize you could reset while driving. I waited until I got home. It's weird operating autopilot with no visuals at all.

OK - I have been off the forum for a little bit. Apologies.

Update on my screen issue:

I finally got fed up and called Tesla service number late at night on a 2 hour commute. Explained what was up and htey made an "emergency" appointment for me the next day. I head in, they take my car and I take a model S loaner (feels so much more stable, but also so much more cluttered!).

Tech agent calls me the next day and says "Yep, you had a faulty main display, we are swapping it out and will call you when its done in a day or two".

Fast forward 2 days and it was ready for pickup. I had to reset everything as if it was a new car again, but that was no big deal.

Haven't had a single issue since then (except a flat tire from hitting a deep pothole with the 20's when the tire pinched on the rim).
