TESLA Model S & Model X (2017–2020)
What the hazard is
A reduced or loss of power steering assist while driving increases the risk of an accident, causing serious injury or death to vehicle occupants and other road users.
What to do
The firmware release 2022.36.5 will begin deploying to affected vehicles by Tesla. Owners of affected vehicles may also contact their authorised Tesla dealer to make an appointment to have the firmware updated, free of charge. Note: No further action is necessary from owners whose vehicles are equipped with firmware release 2022.36.5 or a later firmware release.
Defect
Due to a recently changed software calibration issue, the Electronic Power Assist Steering system (EPAS) may not operate as intended. This may result in a reduced or loss of power steering assist and could require greater steering effort from the driver particularly at low speeds. Upon experiencing reduced or lost power steering assist, an audio alert will trigger, and a visual alert will appear on the instrument cluster.
