NHTSA Complaint #11700490 — 2013 TESLA MODEL S

November 20, 2025 To the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation Subject: Safety Defect Complaint – Tesla Model S I am submitting this complaint regarding a serious and dangerous safety defect involving my Tesla Model S. Safety Defect Summary:    •   After the high-voltage battery failed, the vehicle would not enter Neutral.    •   I had to use Tow Mode in the middle of a street on a hill to avoid blocking traffic.    •   Once in Tow Mode, the car could not enter Park and the emergency/parking brake would not engage.    •   The car became completely free-rolling, posing danger to myself, other drivers, and pedestrians.    •   When Tesla returned the car to my home, their technicians also could not get the vehicle into Park or activate any emergency braking system.    •   The car is currently stuck in Tow Mode in my driveway with physical objects placed behind the wheels to prevent it from rolling. Why This Is a Safety Hazard: A vehicle that cannot shift into Park, cannot use its emergency brake, and remains free-moving after a failure represents a serious safety defect. This occurred without warning and left the vehicle unsafe to operate or even store. Request: I respectfully request that NHTSA investigate this as a potential safety defect affecting the Tesla Model S when the high-voltage battery fails. A car should never lose all ability to secure itself.
