Amazon’s self-driving vehicle unit, Zoox, is recalling 332 vehicles in the U.S. The action stems from a critical software flaw affecting the fleet.

The U.S. National Highway Traffic Safety Administration (NHTSA) confirmed the issue. NHTSA stated that an error in the Automated Driving Systems (ADS) software poses a significant risk. The flaw could cause vehicles to stop unexpectedly or cross into oncoming traffic, thereby increasing the risk of a crash.

While the recall affects a small number of units, it impacts the perceived safety and reliability of Amazon’s autonomous driving technology. This technology remains a key area of future growth for the company. No immediate market reaction analysis is available following the announcement.
