This happen to anyone?
Completely unnerving. Driving along, highway speed in a straight line with enhanced auto pilot, navigate on auto pilot on, and both screens go black.
Post MCU 2 upgrade.
FSD computer installed.
V 10.2 installed

Two minutes later they are rebooting.

So if you’ve ever wondered about the architecture of the car, obviously the displays are luckily not the same computers controlling the car a.k.a. the steering, brakes, and accelerator servos.

I've had this happen twice in the past 3 months (April 2019 build, MCU2 HW3). Hadn't happened at all prior to that when I purchased the vehicle (June 2019). I had it happen a few times with the previous Model S I owned (March 2017 build, MCU1).

Recently happened to me, but in the garage, after charging overnight. Both screens black; nothing happened when I stepped repeatedly on the brake. Called Roadside Assistance. The agent couldn't connect remotely to the car OTA. He told me to depress both scroll wheels for a full 2 minutes, which was successful in booting up the car. The agent recommended driving directly to the nearest SC, but they would have none of it. The SC said I must make an appointment, which I did. They can diagnose the car remotely, and order parts before the appointment.

Had this happen two (more) times in the past week. Makes me wonder if there is a recent fault that has been introduced in the software, or if this indicates a larger hardware degradation problem.

What software versions are you all using? Op says 10.2 but am unfamiliar with that. I ask because my car just alerted to install 2021.4.11. I am currently on 4.6.

I have MCU2 HW3. I have not seen this behavior so far. Wonder if new version is being pushed to address this.

Also happened to me just a day after upgrading to MCU2. I knew this was probably just a spontaneous reboot. I was not happy that the IC and MCU2 are integral in such a way that both go out at the same time. IC1 and MCU1 aren't tied together in the same way and you could reboot them independently of each other. So now when the MCU2 reboots, you lose all display.

Was hoping MCU2 would be more stable and would never have these MCU1 type issues :(

Happened to me today. Like everyone else, just normal driving when both screens went black. I was turning around to go home when they both came back. I am on 2021.4.11

had this a few days ago on 2021.4.11. Really unsettling to not even have a speedometer for a few minutes. I've had it happen a few times on older software too.
