Waymo plans to voluntarily issue a software recall with federal safety regulators related to how its robotaxis operate around school buses, the Alphabet-owned company told News.
The voluntary software recall will be filed early next week, according to the company. Waymo said as soon as the issue was identified it updated its software on November 17. The company contends this update has meaningfully improved performance to a level better than human drivers in this important area.
Software recalls have become more common in the age of modern passenger vehicles — and now robotaxis — in which operations are handled by software. These updates, or fixes, are often made prior to the official recall but still carry weight when filed with the federal government.
Waymo’s decision follows increased scrutiny by the National Highway Traffic Safety Administration (NHTSA) and criticism by officials in Atlanta and Austin over how its robotaxis perform around school buses.
NHTSA’s Office of Defects Investigation (ODI) opened its initial investigation into Waymo in October after seeing footage of its autonomous vehicle maneuvering around a stopped school bus — with its stop sign extended and lights flashing — that was unloading kids in Atlanta. In that incident, a Waymo robotaxi crossed perpendicularly in front of the school bus from its right side. The autonomous vehicle then turned left around the front of the bus before traveling down the street.
Other similar incidents popped up in Austin, where the company also operates a robotaxi service with partner Uber. Austin School District officials contend, in a letter available on NHTSA’s website, that at least five of these occurred after Waymo said it updated its software.
The agency sent a letter December 3 to Waymo asking for more information about its self-driving system and operations following reports from the Austin School District that its robotaxis illegally passed school buses 19 times this year. Regulators requested detailed information about its fifth-generation self-driving system and operations.

“While we are incredibly proud of our strong safety record showing Waymo experiences twelve times fewer injury crashes involving pedestrians than human drivers, holding the highest safety standards means recognizing when our behavior should be better,” Waymo Chief Safety Officer Mauricio Peña said in an emailed statement. “As a result, we have made the decision to file a voluntary software recall with NHTSA related to appropriately slowing and stopping in these scenarios. We will continue analyzing our vehicles’ performance and making necessary fixes as part of our commitment to continuous improvement.”
No injuries occurred related to the vehicle behavior addressed by this recall, according to the company, which has emphasized that safety is its top priority and it will continue to work with NHTSA.
The company says it will continue to investigate, track, and implement more updates as needed.
Waymo made a voluntary software recall earlier this year as well as two in 2024, including one that was issued after a Waymo vehicle in Phoenix, driving without a human safety operator, collided with a telephone pole in an alley during a low-speed pullover maneuver.
