TL;DR
Waymo has voluntarily recalled nearly 4,000 robotaxis after one vehicle was swept into a flooded road in San Antonio. The recall is due to a software issue that failed to route around floodwaters. The company plans to issue an OTA update and has implemented interim safety measures.
Waymo has recalled 3,791 of its robotaxis following a recent incident in San Antonio where a vehicle was swept away after driving into a flooded road, with no injuries reported. The recall was filed with the National Highway Traffic Safety Administration (NHTSA) and highlights ongoing challenges in autonomous vehicle safety amid severe weather conditions.
The incident occurred last week when a Waymo robotaxi, which was unoccupied at the time, entered a flooded area and was carried away by floodwaters. According to Electrek, the vehicle’s routing system failed to recognize the danger posed by the flooded street, despite the presence of environmental cues that should have prompted a detour.
Waymo stated that it will deploy an over-the-air (OTA) software update aimed at improving the vehicle’s ability to detect and avoid flooded roads. The company has also implemented interim constraints, including limiting access to areas where flash flooding may occur, while the software patch is being finalized.
This incident marks the second flood-related safety concern involving Waymo’s fleet in San Antonio within the past month. The company has temporarily halted operations in the city but plans to resume later this week once the software update is in place.
Why It Matters
This development underscores the ongoing challenges autonomous vehicle systems face in handling unpredictable weather conditions, such as flooding. It also raises questions about the robustness of current AI algorithms in real-world scenarios, especially as self-driving vehicles become more widespread. The recall and software update demonstrate Waymo’s response to safety concerns, but also highlight the need for continued improvements in environmental perception and decision-making systems in autonomous vehicles.

Background
Waymo, a leader in autonomous vehicle technology, has previously recalled vehicles for various issues, including software glitches and safety concerns. The recent flood incident is part of a broader pattern where weather-related events expose limitations in self-driving systems. San Antonio has been a testing ground for Waymo’s fleet, but severe weather events like flash floods present unique operational challenges. The company’s proactive recall and safety measures reflect ongoing efforts to enhance vehicle reliability and public trust.
“We are committed to safety and are taking immediate steps to address this issue through software updates and operational constraints.”

Key Questions
What caused the vehicle to drive into the flooded road?
Waymo’s current autonomous driving system failed to recognize the floodwaters as a hazard, which is being addressed through a software update.
Are all Waymo vehicles affected?
The recall involves 3,791 vehicles, but the incident appears related to environmental perception challenges rather than a systemic hardware fault.
Will Waymo’s robotaxis operate in flood-prone areas again?
The company plans to limit access to areas where flash flooding may occur until the software update is complete and tested.
When will the vehicles be back on the road?
Waymo has indicated that operations in San Antonio are expected to resume later this week after the OTA update deployment.
Could this incident happen again?
While the software update aims to improve flood detection, the unpredictable nature of severe weather means some risk may remain until further technological advances are made.
