Waymo is recalling nearly 4,000 robotaxis after more than a dozen incidents in which the autonomous vehicles entered closed freeway construction zones, according to a National Highway Traffic Safety Administration (NHTSA) recall report.

The recall affects 3,871 vehicles equipped with Waymo’s 5th Generation Automated Driving System.

According to NHTSA, the software issue could allow a vehicle to enter a closed freeway construction zone and continue traveling at posted speeds. Regulators said affected vehicles may avoid or fail to recognize certain construction-zone closures because of the software defect.

Waymo estimates that all 3,871 vehicles covered by the recall are affected.

According to the recall report, Waymo’s Field Safety Committee began reviewing the issue in late April after examining six incidents in which robotaxis drove past ramp closure signs and entered freeway construction zones.

The committee met again in May after identifying seven additional instances involving active construction zones in the San Francisco Bay Area.

As a result of the 13 reported incidents, Waymo implemented freeway-driving restrictions while engineers worked to identify the root cause and develop a remedy, according to the filing.

The recall covers Waymo 5th Generation Automated Driving Systems manufactured between May 17, 2022, and May 19, 2026. As of June 13, a software remedy remained under development, according to the filing.
