Amazon-owned Zoox issued a software recall on Friday for its entire fleet of 105 public-road robotaxis, after one of its vehicles drove into a smoke-obscured active fire scene on June 20, per the NHTSA recall document.U.S. Department of Transportation Part 573 Safety Recall Report | Source: NHTSAThe vehicle was carrying no passengers. It encountered heavy smoke that obscured an active emergency scene that had not been cordoned off with traffic cones. The robotaxi braked hard while attempting to steer away, then came to a stop inside the scene.A Zoox teleguidance tactician took remote control of the vehicle and reversed it out of the area, allowing first responders to close two of the three lanes running through the scene with cones after the fact, per Engadget.Zoox fixes how its robotaxis respond to heavy smokeZoox investigated the incident and held several rounds of talks with NHTSA through late June and early July on severity, recurrence patterns, and root cause. The company settled on the recall July 7 and shipped the software update to its fleet on July 15, per the NHTSA filing.The company said that the update “enhances existing capability of detecting and responding to heavy smoke”, adding the ability to spot and react to thick smoke in certain conditions. Zoox owns and directly controls the entire recalled fleet, so no third-party owners or dealers had to be notified under federal recall rules.Zoox currently offers free rides in parts of Las Vegas and San Francisco and lets select users hail rides in small zones in Miami and Austin. As Cryptopolitan earlier reported, the Las Vegas free-ride operations began in September 2025 with Zoox’s purpose-built vehicles that have no steering wheel or pedals.NHTSA warns AV firms after emergency-scene failuresThe Friday recall filing arrived a day after NHTSA Administrator Jonathan Morrison sent a public letter to autonomous vehicle developers warning them to stop interfering with first responders. Morrison identified “a clear pattern of driverless AVs interfering with law enforcement and other first responders,” citing incidents in which AVs drove into active emergency scenes, blocked ambulances, or failed to recognize flashing lights, flares, smoke, fire, or traffic cones.Morrison told developers that emergency scenes are “not rare or extreme edge cases” and called on companies to focus resources on the problem, with solutions required by end of month. That reframing matters because it moves emergency-scene detection from an area where AV companies can defend gaps as unusual circumstances to one where NHTSA treats gaps as functional failures.Zoox had settled its recall internally by July 7. Morrison’s letter went out July 8. The Friday filing under NHTSA’s recall process converts an internal software update into a public accountability act.Waymo recalls show the same first-responder riskZoox is not alone. Alphabet’s Waymo, the leading paid robotaxi operator in the US, recently recalled thousands of vehicles and suspended freeway operations after its cars drove through construction zones at speed.Reports had previously counted at least six incidents through March 2026 in which first responders had to physically move Waymo robotaxis away from an emergency scene.Zoox previously issued several software recalls last year to address unrelated issues, including a March 2025 update addressing a hard-braking issue NHTSA had been probing since 2024, and two May 2025 recalls after a Las Vegas collision with a passenger car and an e-scooter strike.Zoox’s commercial launch hinges on NHTSA cooperation. Because its purpose-built robotaxis ship without a steering wheel or pedals, the company needs an exemption from certain Federal Motor Vehicle Safety Standards. NHTSA has separately floated dropping the brake-pedal requirement for vehicles designed to run fully autonomously. The FMVSS exemption path is the specific reason Zoox filed a Friday recall on top of the July 15 software deployment.Don’t just read crypto news. Understand it. Subscribe to our newsletter. It's free.
