A Waymo Robotaxi Just Triggered an AI Doom Loop after it Got Caught on a Flooded Phoenix Street
Waymo already recalled thousands of robotaxis in 2026 after its self-driving cars kept driving straight into floodwater.
Months after that recall, one more Waymo vehicle rolled straight into a flooded Phoenix street and could not figure out what to do next.
What that car did for the next ten minutes is the part every human driver on that street will never forget.
The Recall That Was Supposed to Fix This
In April 2026, an unoccupied Waymo vehicle drove into a flooded roadway in San Antonio on a street with a 40 mile-per-hour speed limit and got stuck.
Waymo's engineers found the real flaw: the software would slow down for standing water, then decide it was safe enough to keep going anyway.
The company filed a voluntary recall covering 3,791 vehicles with the National Highway Traffic Safety Administration.
Service was suspended across Atlanta, San Antonio, Austin, Houston, and Dallas while engineers pushed an emergency software patch.
Waymo told regulators the fix added new weather constraints and updated its vehicle maps.
That recall happened in May 2026.
Phoenix Already Watched This Software Fail Once This Year
The flood was not even the first time Phoenix caught Waymo's software making the same kind of mistake.
In April 2026, Waymo vehicles drove into active freeway construction zones in Phoenix six separate times, blowing past ramp closure signage on April 11 and five more times on April 19.
Seven more vehicles crossed into a closed construction lane in the Bay Area the following month.
Waymo recalled 3,871 vehicles over the defect in June 2026, and the recall notice itself warned that "driving at speed in a freeway construction zone increases the potential for collisions."
Three recalls in one year, two of them tracing back to Phoenix, and the pattern is the same every time: the software sees a hazard, and it does not know what to do about it.
Federal Regulators Are Already Watching This Company Closely
The flood is not even Waymo's only open federal investigation.
Waymo vehicles blew past stopped school buses with flashing lights and deployed stop arms in Austin at least 19 times after the 2025 school year began, with children visible near the crosswalks.
The Austin school district's police chief said Waymo "refused to cease operations" even after being cited 20 times, and the National Highway Traffic Safety Administration opened a formal investigation in December 2025.
In January 2026, a Waymo vehicle made contact with a child who stepped into a Santa Monica street outside a marked crosswalk near an elementary school.
The child was not injured, and Waymo says the car braked hard enough to cut its speed nearly in half before contact.
Regulators opened another investigation anyway, because a driverless car hitting a child outside a school is not the kind of incident anyone waits to explain.
Weird how AI cars are regulated by the National Highway Traffic Safety Administration but we’re told that any state-level attempt to regulate the AI industry is a terrible idea.
Conservatives are not fans of regulation in general but we are fans of states rights.
And since the people who are behind all the AI keep saying it’s dangerous perhaps it’s worth looking at.
Human Drivers Handled It Fine and the Robot Could Not
Four months later, a Phoenix street flooded during a storm, and two Waymo vehicles rolled straight into it anyway.
One managed to push through.
The other did not.
Witness Roger Pelkey filmed the second car rocking forward and backward in the standing water for more than ten minutes, unable to commit to a direction.
"There were actually two Waymos holding up traffic," Pelkey said.
"This one was stuck in an AI loop and frustrating drivers," he added.
At one point the vehicle nearly backed directly into another car behind it.
Every human driver on that flooded street simply steered around the water and kept going.
The multi-million dollar autonomous system with a nationwide recall behind it just sat there rocking in place, unable to make a decision a sixteen-year-old with a learner's permit makes without thinking twice.
A Company That Had Nothing to Say
Fox Business reached out to Waymo for comment on the Phoenix incident and received nothing back.
That silence matters, because this is not a new or unknown failure mode.
Waymo told federal regulators five months earlier that its software had already been fixed.
Robotaxis are already running driverless, twenty-four hours a day, in cities across the country, hauling paying passengers through the same kind of weather that just trapped one of them in a loop on video.
Waymo co-CEO Tekedra Mawakana has said, "We want to be the world's most trusted driver."
What Phoenix drivers watched instead was a car that could not tell floodwater from a green light.
Trust is not what a car earns by rocking back and forth in a flood for ten minutes while everyday drivers steer around it without a second thought.
