Garbage Text Characters on MCU Display - Fix??

[Padelford]

In the process of trying to recover voice command capabilities, I double-scroll-wheel rebooted the MCU. This didn’t help voice commands, but now I see garbage text characters in the Nav and owners manual displays:

Powering down the whole vehicle and restarting doesn’t stop the garbage text characters. Has anyone had this happen, and what was the fix? I have an SC appointment Monday. Thanks!

What firmware version are you on? A lot of us get this.

2018.50.6. This is the first time EVER this has happened to me. Prior to the thumb-wheel reboot, the MCU display was fine.

Did you step on the brake when you did the reboot? Either way reboot it again, both scroll wheels and brake pedal. I do this after the car gets any update.

I was not aware that steppping on the brake pedal was part of the vehicle reboot procedure. I’ve successfully rebooted my S and then X multiple times over the years without using my “boots”.

Yup have this issue too. Service center acknowledged but said no fix yet.

My understand is there are two levels of restarts. Without the brake pedal is display level only. With brake pedal is power system, suspension and brake systems, and display functions. At least this is what the Tesla phone support guy told me when I was stuck in a parking lot.

Epilogue: I tried rebooting the MCU yesterday with the brake pedal pressed, and the garbage characters went away. I cancelled my SC appointment for today. Thanks for the comments.
