Zoox, a subsidiary of Amazon that operates robotaxis, has initiated a voluntary recall of its software for 270 vehicles. This decision comes after the company temporarily halted its autonomous vehicle operations to conduct a review following an incident in Las Vegas last month, where a Zoox vehicle collided with a passenger car. According to a report filed with the National Highway Traffic Safety Administration (NHTSA), the collision did not result in any injuries. As reported by CNBC, Zoox has resumed its normal operations after implementing the necessary software update.

Following a thorough analysis and rigorous testing, Zoox identified the root cause of the issue, as stated in a blog post published today. The company has since issued a software update that has been applied to all Zoox vehicles. As a result, all Zoox vehicles currently on the road, including both the purpose-built robotaxi and the test fleet, are now equipped with the updated software.

Last year, the NHTSA conducted an investigation into issues with Toyota Highlander cars that were equipped with Zoox’s automated driving system and exhibited unexpected braking. Recently, car models retrofitted with the Zoox system began testing and mapping in Los Angeles.
