Model X driver Walter Huang, 38, died after his car crashed while in Autopilot mode on March 23.
Without being a party to the NTSB investigation, the electric-vehicle company will no longer be made aware of the information that comes out of it before the general public.
Tesla received criticism for a statement it released after the crash, relaying details of the crash and appearing to blame the driver.
“The driver had received several visual and one audible hands-on warning earlier in the drive and the driver’s hands were not detected on the wheel for six seconds prior to the collision,” the company said in a statement.
Shares of Tesla were down slightly to US$299 late Thursday afternoon.
