First time that happens to me … *BOTH* screens went out while I was driving!

I have a 2017 MS75. HW had been upgraded to HW3 with FSD.

I have recently upgraded my MCU1 to MCU2. Before the upgrade, while the center screen will occasionally go black, the screen behind the steer wheel had always stayed on. This is the first time I have both screen went dark on me. Beside turn signal not making a sound, there was no speedometer either. (Hmmm …. Wonder if I can use that as an excuse for speeding :)

Good thing is that they both came back relatively quickly.

Anyone seen this behavior before?

My 2020 Long Range has done this once, maybe twice. I think this happens after an update, where the updates didn't entirely complete getting installed, so the thing reboots when it finally screws up after running awhile. It has not been a regular or continuous thing for me, so I haven't worried about it. Pretty scary when it goes dark at night while rebooting.

Can someone confirm that unlike MCU1 where the center console is separate from the driver’s console, with MCU2, they are integrated … so when the center console went out, it would take the driver’s out too :-(

That is right. With MCU2 the instrument cluster is just a remote screen from MCU, so if it crashes both screens go out until MCU2 reboots.

We've also been discussing it here:

It happens to me maybe once every 4-8 weeks (April 2019 build, MCU2 HW3).

Hello. Brand new to forum. 2020 S Perf. Lost both screens while driving twice since new. Also acceleration mode stuck on
"chill". Unable to change it on screen. Anyone else seen this ?

Check this setting and change from Speed Limit Mode if it is enabled:

"Note: When Speed Limit Mode is enabled, the acceleration setting (Controls > Driving >
Acceleration) is automatically set to Chill (see Acceleration Modes on page 74)."

Yes... I have a Model X and this is happening often (several times a day). In for service twice with replacement of memory chip and firmware upgrade but it still is happening. I get the impression from all these posts that there may be more than one reason why this occurs but they dont really know for sure. Glad I have WAZE on my phone so i wont get lost.

Both screens on my 2020 Model S go out like every 2 months as the system reboots. All critical systems and signals continue, but it is scary at night when it all goes black inside. This is just bad programming. They are (always) working on it.
