My M3 only drive 1500+ mile, i got my first alert on the morning. the monitor shows Car Needs Service - Steering Assist Reduced tried the reboot, went out and back in. come back to the car a few hours later, and it still shows on next day. driving is fine, no strange feel i can tell. but still schedule the service on next day, and got a loaner MS. will update once Tesla find out what happened.
