Amazon.com Inc.’s driverless-car business issued a software recall across its fleet after one of its robotaxis struggled to navigate through heavy smoke, the latest in a string of incidents involving autonomous vehicles at emergency scenes. Zoox released a software update this week for all 105 vehicles operating on public roads, according to a document published July 17 on the National Highway Traffic Safety Administration’s website. The move affects the company’s purpose-built robotaxis and not a separate testing fleet of retrofitted vehicles. The voluntary recall stems from an incident on June 20, when an unoccupied Zoox vehicle approached the scene of a fire that was obscured by heavy smoke, braking hard while attempting to steer away before coming to a stop, according to the document. Later, first responders placed traffic cones at the scene, blocking two of the three through-lanes. No one was injured, and Zoox said it’s not aware of any other instances of this kind. In a statement to Bloomberg, the company said the software update “enhances the existing capability of detecting active EV scenes by adding the ability to detect and respond to heavy smoke in certain situations.” Alex Fraser of Cox Fleet discusses how fleets should respond as roadside breakdowns test
