"Steering Assist Reduced" Error - '21 MSLR

[Marcust99]

Have a '21 MSLR with 6800 miles. Today I go to get into the car and at first I get an alert "parking assist unavailable". That seemed to
go away but then another came on the console right after: "Steering assist reduced - steering may require increased effort".

Interesting thing in that the steering seems normal still.

I've restarted the car and the error didn't clear. Let is also be known that the car has been randomly rebooting when I get into drive
it lately as well. Sent this info to Telsa waiting to hear back.

Anyone else ever get this error??

Probably worth making a service appointment.

Just FYI i had the same error this weekend on my ‘17 MS 90D w/ MCU2, FSD, …. but it came with an actual loss of power steering. It was a full-on brown stain moment while turning a corner the wheel jerked out of my hand w/ Power Steering failed and i almost slammed into another car in the oncoming lane.

I have soft and hard reset the car (including a 12v / high power battery disconnect) and the error messages and power steering failure are still presenting. I have made an appointment w/ service but the car is effectively un-drivable around town without power steering.

Had the same issue today. Any ideas how to reset? I cannot even get out of my garage because the steering is so hard.

I got the same message today, but completely went away in about 20 secs when I continued to drive. No loss of post steering whatsoever.

The SC found the plug to the power assist was not all the way plugged in. You can check that?

Are you able to pinpoint to where that is located for future reference?

Sorry. No. I think they found it and fix it in about 5 mins + a test drive. BTW - No more issues with the steering so far.
