Amazon-owned autonomous vehicle unit Zoox is recalling its entire fleet of 105 driverless vehicles following an incident where an unoccupied vehicle failed to detect heavy smoke at an emergency fire scene. The recall comes amid heightened scrutiny from federal safety regulators regarding autonomous vehicles interfering with first responders.
The self-driving industry faces mounting regulatory pressure over vehicle interactions with emergency personnel. Jonathan Morrison, head of the U.S. vehicle regulatory agency, recently issued a letter to autonomous vehicle developers stating that the National Highway Traffic Safety Administration has documented multiple instances of robotaxis driving directly into active emergency scenes, according to reporting from Reuters.
Zoox Recall Triggered by Smoke Incident
The recall affects 105 autonomous vehicles operated by Amazon unit Zoox. The action was prompted by a June 20 event involving an unoccupied Zoox vehicle that encountered heavy smoke obscuring an active emergency fire scene. According to the company, the vehicle entered the area, braked hard while attempting to steer away, and ultimately came to a stop.
While operating under teleguidance, the vehicle reversed before first responders placed traffic cones to block two of the three lanes. In response, Zoox stated that a software update is being deployed to enhance the fleet’s existing capability to detect and respond appropriately to heavy smoke.
Federal Scrutiny Over First Responder Interference
Federal regulators have signaled that autonomous vehicle developers must rapidly address recurring safety issues involving emergency response coordination. In his letter to the industry, Morrison noted a clear pattern of driverless vehicles interfering with law enforcement and firefighters.
“blocked the paths of ambulances and firefighters, or failed to recognize and respond to basic safety conditions like flashing lights, flares, smoke, fire, and traffic cones.”

Federal regulators also emphasized the broader public safety stakes involved in these software limitations.
The regulatory agency scheduled meetings with vehicle developers to solicit concrete solutions to these safety vulnerabilities.
Incidents Involving Waymo Fleets in Texas
Concerns extend beyond a single manufacturer. Local media in Texas reported that a Waymo autonomous vehicle in Dallas partially blocked a route fire trucks were using to respond to an apartment building fire in late May. Additional footage has documented Waymo vehicles blocking an ambulance and driving through active police scenes.
Federal oversight continues to expand as both the National Highway Traffic Safety Administration and the National Transportation Safety Board investigate separate incidents. These inquiries include autonomous vehicles passing stopped school buses with their lights activated in violation of Texas state law.
