It follows a two-year study of crashes at Elon Musk’s company that occurred while Autopilot was in use.

The recall affects nearly every Tesla sold in the United States since the Autopilot feature was introduced in 2015.

Tesla claimed it would remedy the problem with a “over-the-air” software upgrade.

The update occurs automatically and does not require a visit to a dealership or garage, but the regulator still refers to it as a recall.

Although Autopilot is intended to assist with steering, acceleration, and braking, the automobile cannot be controlled without driver input.
