According to a safety recall report released by the National Highway Traffic Safety Administration earlier this month, Tesla has recalled more than 40,000 Model S and Model X vehicles in the United States due to an issue that could lead to a reduction or loss of power steering assistance. The vehicles were built from 2017 to 2021.
A firmware release that updated the vehicles electronic power steering system calibration values caused some vehicles to incorrectly classify severe road conditions as unexpected steering assist torque, resulting in a potential steering problem assisted, according to the NHTSA report. Shortly after Tesla rolled out firmware version 2022.36 in October, the electric car maker identified an increased rate of alerts related to calibration values on some vehicles with the firmware installed.
According to NHTSA, reduced or lost power steering can be dangerous, especially when driving at slower speeds, because the increased effort required to steer the vehicle can increase the risk of a collision. At this time, Tesla is not aware of any incidents related to the issue resulting in injury or death.
Tesla has released an over-the-air software update to recalibrate the power steering system, and no further action is required for owners of affected vehicles with firmware version 2022.36.5 or later installed.
