Tesla Inc. will reportedly fix software problems in more than 1 million vehicles, according to China's official market regulator. The software fix is being mandated to reduce accidents in Tesla's automated vehicles, states the regulator. 

The action is described as a product recall under Chinese regulations, the regulator said, but it was not immediately clear if drivers might need, or would be eligible, to return vehicles to Tesla for refunds.

From 29 May, the US automaker will issue over-the-air software updates to 1.1 million units of its Model S, Model X, Model 3 and Model Y cars, both imported and China-made, the State Administration for Market Regulation said in a statement.

The regulator said the vehicles concerned did not allow drivers to turn off regenerative braking or provide enough warnings when drivers stepped on the accelerator pedal hard, which, combined, could increase the risk of collision.

The update will restore the option of switching off regenerative braking and warn drivers when they step hard on the accelerator pedal, it added.
Tesla was not immediately available for comment.

Regenerative braking works to save energy from the process of slowing a car, feeding the surplus to batteries to increase its driving range. Tesla had disabled the option to switch off the technique on cars produced after 2020.
