Waymo is recalling over 3,800 of its autonomous vehicles due to a software defect that could cause them to enter closed freeway construction zones at highway speeds.
The recall affects Waymo's self-driving taxi fleet across multiple markets. The company identified a software issue that prevents the vehicles from properly recognizing and avoiding closed freeway sections during construction or maintenance work.
According to Waymo's filing, the affected robotaxis could fail to detect closure information and proceed into restricted areas at normal driving speeds. This creates a safety hazard for construction workers and occupants of the vehicles.
Waymo discovered the issue through its internal safety monitoring systems and initiated the recall voluntarily. The company is developing a software update to address the problem and plans to deploy the fix remotely to all affected vehicles.
The recall underscores ongoing challenges in autonomous vehicle development, particularly around edge cases and real-world road conditions. Self-driving systems must reliably process dynamic information—like temporary construction closures—that can change frequently and may not be fully integrated into mapping databases.
Waymo operates robotaxi services in cities including San Francisco, Phoenix, and Los Angeles. The company has steadily expanded its autonomous vehicle operations and has logged millions of miles of real-world driving data.
This is not Waymo's first safety-related action. The company has previously addressed software issues affecting its fleet, though major recalls remain relatively uncommon in the autonomous vehicle industry.
The software update timeline has not been disclosed. Waymo has not reported any accidents or incidents resulting from the identified defect.
