Tesla hopes to rival firms already offering driverless ride-hailing in the US and around the world, such as Waymo, Zoox and Baidu.
The facility will help Zoox grow its robotaxi fleet, eventually producing 10,000 vehicles a year once it's at full scale.
Zoox's recall comes after an unoccupied robotaxi was struck by an e-scooter rider at an intersection earlier this month.
Amazon's Zoox issued a software recall for its robotaxis after a crash in Las Vegas last month, the company said.
