Waymo recalls nearly 4,000 robotaxis for software issues.
Vehicles may accidentally go onto closed highway construction zones.
Waymo vehicles will avoid highways while a fix is found.
Alphabet, parent company of Google, has recalled 3,871 units of its Waymo autonomous robotaxi in the United States because the vehicles can drive onto closed highway construction zones. The issue is software-related, prompting a recall with the National Highway Traffic Safety Administration (NHTSA).
Waymo says a fix is currently under development, and the vehicles will be restricted from freeway driving during the interim. When a solution is found, the company will update the 5th Generation Automated Driving Systems (ADS) in the cars to detect when the vehicle is in and to avoid entering construction zones.
