Alphabet's Waymo had recalled as many as 444 vehicles and fixed an issue with its automated driving systems (ADS) software, the U.S. National Highway Traffic Safety Administration (NHTSA) said Thursday.
Its fifth generation ADS systems with versions released prior to Dec. 20 may have inaccurately predicted the movement of a towed vehicle, according to the agency.
The company has updated the software and all affected vehicles were repaired as of Jan. 12, the NHTSA said.
The notice about the fix comes days after a crowd vandalized and set fire to a Waymo self-driving car using a firework in San Francisco, marking the most destructive attack so far on driverless vehicles in the United States.
California lawmakers and labor unions rallied on Monday to call for laws to not allow autonomous trucks without human drivers, amid rising safety concerns after accidents involving self-driving taxis from General Motors and Alphabet.
Separately, the NHTSA said electric automaker Lucid Group also recalled 189 of its Air vehicles to fix a software issue that could have resulted in loss of drive power.
Lucid released an over-the-air update in October 2023 to fix the issue, the agency said.
Waymo and Lucid did not respond to Reuters requests for comment.
