TL;DR
Waymo is voluntarily recalling approximately 3,800 robotaxis across the U.S. to address software flaws that may cause vehicles to drive into standing water. The recall follows recent incidents, including a flooded-road event in San Antonio.
Waymo is recalling about 3,800 of its robotaxis in the U.S. to fix software issues that could cause vehicles to drive onto flooded roads, following recent incidents in Austin and San Antonio. The move is aimed at addressing safety concerns as the company continues to expand its autonomous fleet.
According to a letter posted on the National Highway Traffic Safety Administration (NHTSA) website, Waymo’s voluntary recall affects vehicles equipped with its fifth and sixth-generation automated driving systems. The recall was prompted by reports of vehicles driving onto standing water, including a recent incident in San Antonio on April 20, where a Waymo vehicle entered a flooded street and was swept into a creek with no passengers onboard.
Waymo stated that it has identified an area of improvement related to untraversable flooded lanes, especially on higher-speed roads, and is working to implement additional software safeguards. The company also said it has limited the areas where its vehicles operate during extreme weather conditions to prevent similar incidents.
In a statement, Waymo emphasized that it provides over half a million trips weekly across multiple U.S. cities, including San Francisco, Los Angeles, Phoenix, Austin, and Miami, and highlighted its commitment to safety. The company also confirmed that its operations in San Antonio remain temporarily suspended as it prepares to resume public rides.
Why It Matters
This recall underscores ongoing safety challenges faced by autonomous vehicle developers as they expand into complex urban environments. The incidents involving flooded roads highlight the importance of robust software systems and operational safeguards. For consumers and regulators, these events may influence future safety standards and public trust in autonomous mobility.

The April 20 flooding incident in San Antonio, which prompted the latest recall, is part of a broader pattern of safety concerns as the company pushes into new markets and weather conditions.
