Waymo Recalls 3,800 Vehicles Due to Highway Entry Glitch

Alphabet’s autonomous driving subsidiary Waymo disclosed on June 18, 2026, that it has filed a voluntary recall with the National Highway Traffic Safety Administration (NHTSA) for approximately 3,800 of its self-driving taxis due to a software glitch. According to a report by Engadget, the glitch could potentially cause vehicles to enter closed highway construction zones.

Background and Details of the Recall

According to a safety notification document from the NHTSA reviewed by Reuters, Waymo has been working on a software fix and has “restricted freeway operations” in the meantime. The document does not indicate whether any incidents triggered the recall.

Waymo told Engadget that it identified areas for improvement in the vehicles’ performance when encountering highway construction zones. The company stated, “Last month, we proactively restricted freeway driving while implementing improvements, notified state and federal regulators in advance, and decided to voluntarily file a software recall with the NHTSA.”

The company emphasized that such recalls are intended to address software issues and do not necessarily mean that the vehicles will be immediately pulled off the road.

History of Freeway Operations

Waymo’s Jaguar I-Pace-based robotaxis were first permitted to operate on freeways in Phoenix, Arizona, in 2024. Initially limited to employees, the service was later expanded to paying customers. Before this, the vehicles were allowed to operate on highways only when a safety driver was present. At the time, the company released a video demonstrating how the vehicles navigate highways.

Recent and Past Recall Incidents

This recall follows another recall that occurred just a month earlier, in May 2026. That recall involved 3,791 robotaxis after one of the vehicles entered a flooded roadway in San Antonio. Although the vehicle was carried away by the water while unoccupied, no injuries were reported.

Prior to that, there were incidents where the vehicles failed to recognize and respond to school bus stop signs and flashing lights, prompting additional recalls. These cases highlight the challenges of addressing edge cases in autonomous driving technology.

Assessing the Safety of Autonomous Driving

Despite these multiple recalls, Waymo maintains that its fleet of autonomous vehicles operates safely overall. According to the company’s safety impact page, Waymo vehicles are involved in “92% fewer severe or worse accidents” compared to human drivers and experience 92% fewer collisions with pedestrians.

Regulatory Response and Industry Impact

The NHTSA has been heightening its oversight of autonomous vehicles, and this latest recall is seen as part of that trend. While the voluntary recall demonstrates a cooperative stance toward regulators, it could also influence public confidence in the safety of autonomous driving technology.

Waymo’s recall underscores the challenges faced by autonomous systems when navigating the complexities of real-world scenarios. Highway construction zones, in particular, pose unique difficulties due to temporary signage, unpredictable lane changes, and erratic movements by construction vehicles, all of which require highly adaptive sensor and algorithm capabilities.

Editorial Opinion

In the short term, this recall highlights areas where Waymo’s software development process has room for improvement. The restriction on freeway operations could negatively impact user experience. However, the proactive identification and voluntary resolution of the issue are commendable and likely to help maintain a positive relationship with regulators. If the software fix is deployed within the next few months, significant business disruptions may be avoided.

From a long-term perspective, this situation reaffirms the importance of addressing “edge cases” in autonomous driving technology to establish reliability. The difficulty of collecting comprehensive test data for every possible road scenario remains a challenge for the entire industry. The ability to handle unique situations, such as construction zones and flooded roads, could become a crucial differentiator for autonomous driving technologies. Additionally, an increase in recall frequency could lead to higher insurance premiums and regulatory costs.

The editorial team believes that when evaluating the safety of autonomous vehicles, it is essential to consider not only comparisons to human drivers but also the systems’ ability to handle corner cases effectively.
