The National Highway Traffic Safety Administration said Thursday it has closed its initial evaluation of extreme braking and stabilization in 1,194 self-driving vehicles operated by General Motors Co.’s Cruise unit.
The National Highway Traffic Safety Administration said it closed the evaluation after reviewing the Cruze recall and analyzing data, which showed a decrease in sudden braking incidents after software updates.
Earlier this month, the robotaxi unit filed a recall affecting all of its vehicles equipped with Autopilot systems in the United States.
Cruise is still facing investigations by the Justice Department and the Securities and Exchange Commission following an incident last October when one of its robotaxi vehicles struck a pedestrian and dragged her 20 feet (six meters).
Cruise and other self-driving vehicle companies such as Alphabet Inc.’s Waymo and Amazon.com Inc.’s Zoox have come under intense regulatory scrutiny over safety concerns after multiple accidents involving their vehicles.
Cruise, which resumed U.S. operations in April with a small fleet of human-driven vehicles in Phoenix, Arizona, said it had updated the software in all of its supervised test fleet vehicles.
