TL;DR
Waymo has initiated a recall of nearly 4,000 autonomous vehicles after one was seen driving through a flooded roadway. The move highlights safety risks as the company prepares to expand into wetter, more adverse weather regions.
Waymo has recalled 3,791 of its autonomous vehicles equipped with its sixth-generation driving systems due to safety concerns related to driving on flooded roads, according to documents filed with the National Highway Traffic Safety Administration (NHTSA). The recall follows an incident where a Waymo robotaxi, operating without passengers, encountered a flooded roadway and continued to proceed at reduced speed, despite the hazard. This development raises questions about the company’s ability to handle adverse weather conditions as it plans to expand into new markets.
Waymo, a subsidiary of Alphabet, identified the affected vehicles as those using its fifth and sixth-generation autonomous driving systems. The incident involved an unoccupied robotaxi that encountered a flooded section of a road with a 40 mph speed limit, yet continued driving after detecting the flood. The company stated it is working on a remedy, which currently includes updating its vehicles to increase weather-related constraints and improve map data to better handle such conditions.
While no injuries have been reported, the incident underscores the challenges autonomous vehicles face in extreme weather, especially as Waymo prepares to expand into cities with more variable climates such as Boston, New York City, and Washington, D.C. The sixth-generation system, launched earlier this year for high-volume production, is designed to operate across multiple vehicle types, including Zeekr RT minivans and Hyundai Ioniq 5s. This is the first recall involving the sixth-generation system, although the fifth-generation vehicles have been recalled five times previously for issues like passing stopped school buses and collisions with stationary objects.
Why It Matters
This recall is significant because it highlights the safety risks associated with autonomous vehicle operation in adverse weather conditions, particularly flooding. As Waymo plans to expand into regions prone to heavy rain and flooding, the company’s ability to adapt to these environments will be critical. The incident also raises broader questions about the readiness of autonomous vehicle technology to handle unpredictable and extreme weather scenarios, which are becoming more common due to climate change.

Background
Waymo has historically operated primarily in warmer, drier cities such as Phoenix, Los Angeles, Atlanta, and Austin, where adverse weather is less frequent. The company’s move toward East Coast markets represents a new challenge, as these regions experience more frequent and severe weather events. Previous recalls of its fifth-generation vehicles have involved issues like failing to recognize stationary objects and passing stopped school buses, but this is the first recall linked to the sixth-generation system’s performance in weather-related conditions.
“We are actively working on a remedy to improve our system’s performance in adverse weather conditions.”
