Inside the investigation
Zoox has officially pulled its autonomous test vehicles off the road in Atlanta. This follows reports from workers who claimed they were exposed to potentially dangerous gases, including carbon monoxide and hydrogen sulfide, while operating the fleet last month. One contractor, Jay Davis, even filed a complaint with the Occupational Safety and Health Administration (OSHA) after he and others fell ill on the job.
Davis told TechCrunch, “They made us go right back in the field after we said we were throwing up.” According to reports, as many as 40 workers may have been affected, though Zoox claims the number is lower. Employees described strange smells inside the modified Highlander SUVs, with some reporting symptoms consistent with toxic gas inhalation. While Zoox maintains they have not found carbon monoxide, they did acknowledge an "unexplained odor" in six vehicles and identified 28 employees who had been in them.
Moving forward
To address the situation, Zoox has been replacing 12-volt batteries and inspecting exhaust systems for leaks. The company noted that damaged batteries can release hydrogen sulfide, which creates a distinct, sulfur-like scent. While Zoox’s purpose-built, all-electric robotaxis are not involved in this issue, the company says it plans to install CO2 monitors in the test vehicles moving forward.
Zoox stated, “The safety and well-being of our Zoox test fleet operators is our primary concern in this situation.” OSHA has since concluded its inquiry into the matter, and the facility remains at limited capacity while the company continues its investigation.
Why it matters
As autonomous vehicle companies race to scale up, this situation highlights the very human risks involved in testing technology. When rapid growth meets hardware modification, safety protocols become more critical than ever for the workers on the ground.
