NHTSA Complaint #11704380 — 2018 TESLA MODEL S

My 2018 Tesla Model S has a recurring safety-critical defect involving the steering system and the Chassis CAN communication network. On October 20, 2025, the vehicle had to be towed to a Tesla Service Center because it would not power on and displayed multiple safety alerts (traction control disabled, stability control disabled, ABS disabled, and reduced steering assist). Tesla documented that the steering rack was “bringing down the Chassis CAN” and stated the issue might require a new steering rack and coolant pump if it returned. The warnings have now returned, and the vehicle is again showing active alerts for disabled traction control, disabled stability control, and previously reduced steering assist. This is a repeat of the same unsafe condition that Tesla attempted to repair. The car is unsafe to drive and could cause loss of steering control. This is a recurring steering/Chassis CAN failure with major safety system disablement. I am reporting this because the defect affects vehicle control and increases the risk of a crash.
