Tesla is recalling more than 40,000 2017-2021 Model S and Model X vehicles because the electronic power assist steering (EPAS) system may experience a loss of power steering assist when driving on rough roads or after hitting a pothole.
The latest recall was made public in a filing with the National Highway Traffic Safety Administration made public today. Teslas built in Fremont CA and in use in North America, Europe, Australia, Hong Kong, South Korea, Taiwan, Macau and New Zealand are covered by this safety defect.
The problem is caused by “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,” Tesla told NHTSA.
Tesla has released an over-the-air (OTA) software update to recalibrate the EPAS system, free of charge as required by federal safety regulations. Owner notification letters are expected to be mailed 31 December 31 2022. Owners may contact Tesla customer service at 1-877-798-3752. Tesla’s number for this recall is SB-22-00-014. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
