Since the recall, at least 20 Tesla vehicles have been involved in crashes in which the system was thought to be in use, according to a filing on the NHTSA's website.
The "recall remedy" probe follows a three-year investigation by the agency that found safety issues with Tesla Autopilot contributed to at least 467 collisions and 14 deaths from January 2018 through August 2023.
The NHTSA is seeking detailed crash data from the electric vehicle maker since the agency issued the recall update on Autopilot, including data and video stored in or streamed from its cars and retained by the company.
The company hasn't disclosed how many jobs in its Autopilot and vehicle-safety engineering teams may have been cut.
For about a decade, CEO Elon Musk has been promising that Tesla is on the cusp of a self-driving breakthrough.
