NHTSA Complaint #11674412 — 2021 TESLA MODEL X

After completing a 17.5-hour, ~1,000-mile non-stop road trip from Florida to Texas using Autopilot with no interventions or issues, the following week this vehicle experienced a sudden and total steering failure while slowly turning through my residential neighborhood. The steering locked up without warning and caused the car to drift partially into the opposing lane. No power steering warning was shown prior to the failure. Tesla Service diagnosed and replaced both the Front Body Controller (Part #1585663-00-C) and the Steering Gear Assembly (Part #1070801-00-F) under warranty. This is an extremely dangerous failure scenario — had it occurred at high speed, the outcome could have been catastrophic. I am reporting this to ensure it’s documented and investigated, as it appears consistent with similar steering failure complaints in 2021+ Model X vehicles.
