Amazon-owned Zoox has initiated a software recall after its self-driving taxi entered a thick smoke area.

Amazon-owned Zoox voluntarily recalled 105 self-driving taxis to address a software issue that caused the vehicles to not detect thick smoke and drive directly into it. Zoox reported the recall to the National Highway Traffic Safety Administration on July 8th and stated that the company only became aware of the smoke detection issue after an incident last month. The company explained that last month, an empty Zoox self-driving taxi drove into a smoke-filled active fire rescue scene in Las Vegas. This recall comes after the National Highway Traffic Safety Administration urged autonomous vehicle developers to address issues related to emergency personnel.
