All 270 of Zoox’s vehicles have been updated to fix an ‘inaccurately confident prediction’ that could cause a crash.

Amazon.com's self-driving unit Zoox agreed to recall 270 driverless vehicles after an unoccupied robotaxi was involved in an April 8 crash with a passenger car in Las Vegas. Zoox said there were no injuries in the crash involving a Zoox robotaxi and a passenger vehicle.

Amazon's Zoox issued a software recall for its robotaxis after a crash in Las Vegas last month, the company said.
