Your car is in limp mode. Best limp over to the nearest service center if it's not too far away.
When you open the errors on the center screen by pressing the red warning triangle at the top, what are the error codes?

Tried reboot both Icu and mcu but still remain
The same

Are you handy and have access to a voltmeter? Open the frunk and check your 12V battery voltage. Should be more than 13v if the DCDC is working properly.

It's weird but my car did this back in November after what seemed like an update. I was doing something else at the time so I disconnected my 12V for about 10min. When I reconnected the problem went away and hasn't come back since. Also, around the same time others were complaining about 12V batteries and or battery heaters. Not sure if there's a connection but I guess its worth a try.

My 2015 P85D with an original 12V, 55k miles, 98% gen1 Tesla Wall Connector charging nightly to 90% at 40A/240V exhibited the same error after what seemed like an update too. I reported it to Tesla and scheduled an appointment at our local service center. Diagnosis couldn't find anything wrong and I haven't seen the error since... so hoping it was just "a glitch in the Matrix". or "digital termites".
