NHTSA closes Tesla power steering probe after OTA software fix
The NHTSA has officially closed its investigation into power steering failures affecting over 376,000 2023 Tesla Model 3 and Model Y vehicles. The issue stemmed from an overvoltage condition in the steering Electronic Control Unit (ECU) that could damage key components. Tesla released software version 2023.38.4 in October 2023 via an OTA update to prevent this overvoltage. This update formed the basis of an official OTA recall in February 2025. Following deployment, complaints and field reports dropped significantly, leading NHTSA to close the engineering analysis.
- Investigation covered 376,241 Model 3 and Model Y 2023 vehicles in the U.S.
- OTA update 2023.38.4 prevents overvoltage damage in steering ECU
🔎 Why it matters: Version 2023.38.4 and the related OTA recall resolved a critical ECU steering fault in 2023 Model 3 and Model Y.
📈 Upside: The OTA update prevents overvoltage and protects the power steering system integrity.
