TL;DR
Waymo is recalling approximately 3,800 robotaxis after reports of vehicles driving into standing water. The recall addresses software vulnerabilities that could lead to dangerous situations, with the company implementing new safeguards. The incidents highlight ongoing safety challenges as Waymo expands its autonomous fleet.
Waymo is recalling about 3,800 robotaxis in the U.S. following incidents where vehicles drove onto flooded roads, raising safety concerns and prompting a voluntary recall with the National Highway Traffic Safety Administration (NHTSA).
The recall applies to Waymo vehicles equipped with its fifth and sixth generation autonomous driving systems. According to the NHTSA, these vehicles have demonstrated a vulnerability that could cause them to drive into standing water, especially on higher-speed roadways. The incidents include recent episodes in Austin, Texas, where vehicles stalled on flooded streets, and a case in San Antonio, Texas, on April 20, where a vehicle was swept into a creek during a flood with no passengers onboard.
Waymo confirmed that it identified an area of improvement related to untraversable flooded lanes and has filed a voluntary software recall with the NHTSA. The company stated it is working on additional software safeguards and has implemented mitigations to limit operations during extreme weather, specifically avoiding areas prone to flash flooding during heavy rain. Currently, Waymo operates a commercial robotaxi service in 11 U.S. cities, including San Francisco, Los Angeles, Phoenix, Austin, and Miami, with some markets offering limited rider access.
Why It Matters
This development underscores ongoing safety challenges faced by autonomous vehicle operators as they expand into complex urban environments. The recall highlights the importance of robust software safety measures and real-time environmental awareness for AV systems. For the public, it raises questions about the reliability of robotaxis during adverse weather and the regulatory oversight of autonomous vehicle safety.

Background
Waymo has been rapidly expanding its autonomous fleet across multiple U.S. cities, with a focus on commercial robotaxi services. Previous incidents include vehicles failing to yield to school buses in Austin and halting during power outages in San Francisco, causing traffic disruptions. The recent flooding incidents mark a new safety concern, particularly as climate-related extreme weather events become more frequent. The company’s decision to recall and improve its software reflects efforts to address these challenges proactively.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority.”
