In rare cases on certain 2017-2021 Model S and Model X vehicles, the updated calibration values may result in reduced or lost power steering assist due to forces from external road dynamics (i.e., pot holes or bumps) being inadvertently classified as unexpected steering assist torque. Reduced or lost power steering assist does not affect steering control, but could require greater steering effort from the driver, particularly at low speeds. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Reduced or lost power steering assist may require greater steering effort, especially at lower speeds, which may increase the risk of a crash. Description of the Cause : NR Identification of Any Warning that can Occur : Upon experiencing reduced or lost power steering assist, an audio alert will trigger and a visual alert will appear on the instrument cluster.

Tesla is not aware of any injuries or deaths related to this condition. Description of Remedy : Description of Remedy Program : Firmware release 2022.36.5 and later firmware releases revert the calibration values for the EPAS to pre-2022.36 values. As described above, firmware release 2022.36.5 began deploying to affected vehicles on October 19, 2022. As of November 1, 2022, more than 97% of the affected vehicles installed firmware release 2022.36.5 or a later firmware release. No further action is necessary from owners whose vehicles are equipped with firmware release 2022.36.5 or a later firmware release.

How Remedy Component Differs from Recalled Component : Firmware release 2022.36 includes calibration values that may result in reduced or lost power steering assist due to forces from external road dynamics (i.e. pot holes or bumps) being inadvertently classified as unexpected steering assist torque. Firmware release 2022.36.5 reverts the calibration values for the EPAS to pre-2022.36 values. Identify How/When Recall Condition was Corrected in Production : Vehicles in production were not impacted. The condition only affected certain 2017-2021 Model S and Model X vehicles that installed firmware release 2022.36.
