Waymo to recall nearly 3,800 robotaxis over self-driving software bug

• The company is implementing software safeguards and temporary restrictions, including refined extreme weather operations and limited access to flash flood-prone areas while working on a permanent fix
• Waymo faces separate investigations: one by NHTSA after a robotaxi struck a child in Santa Monica in January causing minor injuries, and another by NTSB for a vehicle passing a stopped school bus illegally in Texas
• NHTSA confirmed Waymo has temporarily narrowed its operating scope with increased weather restrictions and updated maps during the recall period

Waymo Recalls 3,800 Robotaxis Over Flooded Road Software Flaw

Waymo, Alphabet's autonomous vehicle unit, announced Tuesday it is recalling approximately 3,800 robotaxis in the United States due to a software bug that could cause vehicles to enter flooded roads at high speeds, creating safety risks.

Key Incident Details:

The recall stems from an April 20 incident in San Antonio where a Waymo vehicle drove into a flooded lane during severe weather. While the vehicle was unoccupied and no injuries occurred, the event triggered a comprehensive review of similar scenarios involving high-speed operations and impassable flooded roads.

Company Response:

Waymo is implementing software safeguards and has enacted temporary mitigations, including:

• Refined extreme weather operations during intense rainfall
• Limited access to flash flood-prone areas
• Updated mapping systems
• Temporarily narrowed operating scope with enhanced weather restrictions

The National Highway Traffic Safety Administration (NHTSA) confirmed these interim measures while Waymo develops a permanent fix.

Additional Safety Concerns:

This recall compounds mounting scrutiny of Waymo's operations. The company faces a separate investigation following a January incident in Santa Monica, California, where a self-driving vehicle struck a child near an elementary school, causing minor injuries. Additionally, the National Transportation Safety Board launched an investigation in March after Waymo vehicles illegally passed a stopped school bus with activated lights in Texas.

Market Implications:

The recall highlights ongoing challenges in autonomous vehicle technology, particularly regarding edge cases like extreme weather conditions. This may impact investor confidence in the commercial readiness of robotaxi services and could prompt increased regulatory oversight across the autonomous vehicle sector.
