Waymo Recalls 3,800 Robotaxis Due to Flooding Software Glitch

Waymo is recalling 3,791 autonomous vehicles in the U.S. following a software issue that allowed a robotaxi to drive into a flooded lane in San Antonio on April 20, 2026. The software flaw may permit vehicles to maintain high speeds when entering standing water, increasing crash risks. Although there were no injuries reported from the incident, Waymo has temporarily suspended its services in San Antonio. The company is working on a permanent solution to enhance safety during extreme weather conditions. This recall highlights ongoing concerns about the performance of autonomous vehicles in complex environments. Waymo operates over 3,000 robotaxis across approximately 10 U.S. metropolitan areas, providing over 500,000 rides weekly. The National Highway Traffic Safety Administration (NHTSA) has been informed of the recall, and Waymo is implementing additional software safeguards.

Key Points: • Waymo recalls 3,791 robotaxis due to a software flaw allowing high-speed entry into floodwaters. • The recall follows an incident on April 20, 2026, where a vehicle drove into a flooded lane without injuries. • Waymo has temporarily suspended services in San Antonio and is working on software updates for safety.
