The National Highway Traffic Safety Administration (NHTSA) closed its investigation into Tesla power steering failures on June 27.
The probe involved approximately 376,241 Model 3 and Model Y vehicles from the 2023 model year.
NHTSA launched the inquiry in July 2023 after owners reported steering difficulties.
The agency ended the engineering analysis following a Tesla recall in early 2025.
Tesla issued an over-the-air software update to prevent overvoltage and overstress in motor drive components.
The technical fix prevents conditions that lead to increased steering effort.
The closure resolves a significant safety inquiry for the automaker.
