Millions of Tesla brand cars circulating on American roads will have to update their autopilot systems.

Reuters reported that Tesla is recalling more than 2 million vehicles in the US to reinstall new protections in its Autopilot advanced driver assistance system. This comes after federal safety regulators flagged safety concerns. This is Tesla’s largest recall ever, covering almost all electric vehicles running on US roads. In its recall filing, the company said the Autopilot control software system has many limitations and may increase the risk of a collision.

The US National Highway Traffic Safety Administration (NHTSA) has spent more than 2 years investigating vehicles produced by billionaire Elon Musk’s Tesla brand. NHTSA said the mechanism to ensure driver attention may be incomplete and lead to misapplication of the pre-crash warning system.

Tesla is expected to begin deploying a remote software update to integrate control features and add warnings after December 12. This is the second recall this year related to the electric car company’s automatic driving system.

Autopilot is Tesla’s technology that aims to allow cars to automatically steer, accelerate, and brake in moving lanes, while enhanced Autopilot can assist with lane changes on highways.

Elon Musk's 'bad luck' at the end of the year: Tesla had to recall almost all electric cars in the US, not knowing if it could "fix errors online" or not - Photo 1.

In Autopilot there is the Autosteer feature, which maintains a preset speed or distance, while keeping the vehicle in the correct lane.

Tesla said it disagrees with NHTSA’s analysis but will deploy an over-the-air software update to “add controls and warnings to encourage drivers to stay focused on driving whenever Autosteer be activated.”

Autopilot has become a standard feature on Tesla models, so the recall could affect the majority of the company’s vehicles.

Currently, Tesla has not yet responded to the question of whether the recall will be carried out outside the US. Additionally, in February, the automaker recalled 362,000 vehicles in the US to update the full self-driving system software (FSD Beta) after NHTSA said the vehicles did not fully comply with traffic safety laws. traffic and may cause an accident.
