NHTSA Complaint #11636516 — 2019 TESLA MODEL 3

My 2019 Tesla Model 3 (RWD) began alerting error messages on the primary dashboard screen saying "Steering assist reduced. Steering may require increased effort." and "Lane Departure Avoidance features unavailable", followed by the power steering going out completely. Steering required significant effort, which was dangerous while turning through intersections or navigating parking lots, and almost caused a collision with other cars. The error goes away after parking the car and powering it off and on again, but reappears after driving short distances (anywhere from 5 to 30 miles). With the error on the screen, sometimes the power steering appears to work without increased effort (but with Lane Departure Avoidance unavailable), but other times the power steering is completely disabled. I received no warnings or alerts prior to the error messages and behavior I described above. I scheduled an appointment with Tesla Service (Plano-Lexington Drive-Service 300 Lexington Dr Plano, TX 75075) through the Tesla app, and after it was accepted, the app asked me to approve a repair estimate of almost $3000 to "remove and replace the steering rack". The replacement item is listed as "STEERING GEAR - LEFT HAND DRIVE (1188832-00-B)" with a unit price of 2,260.00. I contacted Tesla Service and asked if they would just do a diagnosis first to inspect the car, and they agreed and reduced the estimate to just a $215 diagnosis. The morning of my appointment (Jan 17th, 2025), Tesla Service sent me another new invoice for $3,176.36 for a complete steering rack replacement. When I arrived at the service center, the tech said they inspected the logs remotely, and found the steering rack was failing and needed a complete replacement, before even looking at the car in person.
