Tesla is recalling more than 40,000 cars in the United States because of a potential power steering problem.
The recall includes roughly 40,168 Model S and Model X vehicles built between 2017 and 2020.
According to the National Highway Traffic Safety Administration, the vehicles could experience a loss of power steering assist which could increase the risk of a crash.
Tesla says the problem is likely to happen "due to forces from external road dynamics," such as driving on rough roads or hitting a pothole.
The issue is a side effect from the automaker's October firmware release, which changed calibration values for the electronic power assist steering system.
"Reduced or lost power steering assist does not affect steering control, but could require greater steering effort from the driver, particularly at low speeds," the NHTSA said in a recall report.
Upon experiencing reduced or lost power steering assist, an audio alert will
trigger and a visual alert will appear on the instrument cluster.
Tesla has released a software update to recalibrate the system and address the issue. The automaker said that as of Nov. 1, more than 97% of the recalled vehicles have installed the update.

Tesla has identified 314 vehicle alerts that may be related to the recall, but no injuries or deaths have been reported.
The recall comes as Tesla investors continue to sell of stock following CEO Elon Musk's takeover of Twitter. Tesla shares closed down 5% to $197.08 on Monday, at the lowest level since June 2021, Bloomberg reported.
Since Musk closed his Twitter deal on Oct. 27, Tesla shares have dropped over 12%, according to Bloomberg. The report indicates that investors are worried about the billionaire spreading himself too thin among several high-profile ventures and would prefer him to focus on the car company, which is struggling with lower demand and lingering supply chain troubles.
