Nov. 9, 2022—Tesla has announced a recall for some Model S and Model X vehicles with model years from 2017 through 2021. Around 40,000 vehicles are included.
According to Auto Blog, this recall is spurred by a potential loss of power steering assist. Auto Blog reports that the issue stemmed for some drivers after an over-the-air firmware update issued by Tesla in October.
This update recalibrated the electric power assist steering system values to improve detection for "unexpected steering assist torque," as reported by Auto Blog.
Tesla noted an increased amount of EPAS calibration value alerts about a week after the update was issued, which led to Tesla to roll the update back on October 19.
Tesla also said that "97% of vehicles on the road that could have been affected have already been updated with the latest software that rectifies the problem," according to Auto Blog.
The National Highway Safety Administration has said that the EPAS system could be impacted after drivers navigate rough roads or even potholes. While the loss of power doesn't affect steering control, it could lead to an increased amount of effort output for steering by the driver.
