Zoox has issued a software recall covering 105 of its robotaxis after one vehicle failed to safely navigate heavy smoke from an active fire, interfering with an emergency response2.
The incident occurred on June 20, when a Zoox robotaxi encountered heavy smoke from a fire in a traffic lane that had not been cordoned off with cones. "The Zoox vehicle entered the scene, then braked hard while attempting to steer away before coming to a stop," Zoox's recall report states. The vehicle then reversed under the guidance of a remote teleguidance tactician, after which first responders placed traffic cones to block two of the three through-lanes.
Zoox said the June 20 event was the only time one of its vehicles had encountered an issue with smoke of this kind. The software update now rolling out to the fleet "enhances existing capability of detecting and responding to heavy smoke," according to the company.
The recall follows a broader regulatory push. In early July, the National Highway Traffic Safety Administration published a letter demanding autonomous vehicle companies address robotaxis interfering in emergency situations. NHTSA Administrator Jonathan Morrison wrote that the inability to detect and appropriately respond to such situations represents a "functional insufficiency". The agency announced plans to meet with companies before the end of July to discuss the emergency-situation issue.
This is not Zoox's first software recall. The company previously issued one in May 2025 after a vehicle in its fleet collided with a passenger car in Las Vegas. Zoox announced plans in March to expand its service area in Las Vegas and San Francisco and begin testing its software in entirely new cities.
ANALYSIS The recall underscores a core technical challenge for autonomous vehicle perception systems: handling edge-case environmental conditions — such as dense smoke — that fall outside typical driving scenarios. The NHTSA's demand for industry-wide improvements and its planned meetings before the end of July place the issue squarely in a regulatory context that extends beyond Zoox to other autonomous vehicle operators.
