Zoox Issues Second Software Recall After Robotaxi Collision

Amazon-owned autonomous vehicle company Zoox has recently faced significant challenges with its robotaxi software, issuing its second voluntary recall within a month. This latest recall follows a collision on May 8 in San Francisco, where an unoccupied Zoox vehicle operating at low speed was struck by an e-scooter rider after the vehicle braked to yield at an intersection.

The incident resulted in minor injuries to the e-scooter rider, who declined medical attention. Zoox stated that the robotaxi began moving only after the rider fell and stopped shortly after completing a turn, without further contact. The company promptly shared video and relevant data with regulators and issued a software update aimed at improving perception tracking and preventing vehicle movement when vulnerable road users are nearby.

This recall comes just weeks after Zoox recalled approximately 270 vehicles following a crash in Las Vegas involving a robotaxi and a passenger car. That earlier incident raised concerns about the self-driving software’s ability to accurately predict the movement of other road users, a critical capability for safe autonomous operation.

The safety risks of robotaxis moving after collisions are underscored by the experience of Cruise, a competitor backed by General Motors. Cruise’s business suffered after one of its vehicles struck and dragged a pedestrian, highlighting the importance of robust software safeguards to prevent unintended vehicle movement post-collision.

Zoox has not disclosed the number of vehicles affected by the latest recall or detailed how this update differs from the previous one issued in March, which addressed unexpected hard braking that led to collisions with motorcyclists. The company continues to work with the National Highway Traffic Safety Administration as investigations proceed.

Why Software Updates Matter in Autonomous Vehicles

Autonomous vehicle software must continuously evolve to handle complex, unpredictable real-world scenarios. Incidents like those experienced by Zoox reveal how critical perception tracking and decision-making algorithms are to preventing accidents. Each software update represents a vital step toward safer robotaxi operations and greater public trust.

For developers and companies in the autonomous driving space, these recalls highlight the importance of rigorous testing, real-time data analysis, and proactive regulatory engagement. The ability to quickly identify software flaws and deploy targeted updates can mean the difference between innovation leadership and reputational damage.

Looking Ahead: Building Trust in Robotaxi Technology

As robotaxi companies like Zoox refine their software, the focus must remain on safety and transparency. Sharing incident data with regulators and the public helps build confidence in autonomous systems. Meanwhile, continuous improvement in perception and control algorithms is essential to prevent collisions and ensure that robotaxis can safely coexist with pedestrians, cyclists, and other road users.

The journey toward fully autonomous, reliable robotaxis is complex and iterative. Each software recall, while challenging, provides valuable lessons that push the industry closer to a future where self-driving vehicles are a safe and trusted part of everyday transportation.
