Amazon's self-driving subsidiary Zoox has recently announced a voluntary recall of 105 autonomous vehicles due to a software issue that may prevent the system from detecting and responding adequately to dense smoke, posing a potential safety risk in emergency scenarios. This recall was initiated following a specific incident that occurred in Las Vegas on June 20th of this year.
On the day of the incident, an unoccupied Zoox vehicle encountered heavy smoke emanating from a fire scene that was not cordoned off with traffic cones. The vehicle proceeded directly into the smoke, subsequently executed an emergency brake and attempted a turn before coming to a stop. A remote operator directed the vehicle to reverse, after which emergency responders arrived and established a roadblock. Zoox stated this is the only known occurrence of this type to date and that no injuries resulted from the event.
Zoox submitted the recall documentation to the U.S. National Highway Traffic Safety Administration (NHTSA) on July 8th and has since deployed a software update to enhance the vehicles' ability to detect and respond to heavy smoke conditions.
This recall coincides with heightened regulatory scrutiny over how autonomous vehicles interact with emergency personnel. The NHTSA Administrator issued a directive last week to self-driving companies, instructing them to ensure their vehicles yield to emergency responders. He noted the agency has identified a "clear pattern" involving multiple incidents where autonomous vehicles have entered active emergency scenes, obstructed the path of ambulances or fire trucks, or failed to recognize fundamental safety signals such as emergency lights, smoke, or flames.
Amazon acquired Zoox in 2020 for $1.3 billion. The company's driverless vehicles, which lack a steering wheel and pedals and feature a four-seat, face-to-face cabin layout, are currently offering free rides in parts of Las Vegas and San Francisco, with testing also underway in cities including Miami and Austin.
