However, a Tesla spokesperson said the company decided on its own to withdraw from the party agreement on Tuesday and released the statement "to correct misleading claims that had been made about Autopilot".
According to Bloomberg, the NTSB has revoked Tesla's "party status", essentially removing it from the investigation.
"Releases of incomplete information often lead to speculation and incorrect assumptions about the probable cause of a crash", the agency said in its statement.
The family of a driver killed last month in a Tesla vehicle crash has hired law firm Minami Tamaki LLP to explore legal options, the firm said on 11 April, adding the Autopilot feature was defective and probably caused his death.
The family of Huang has hired the law firm of Minami Tamaki to represent it in upcoming suits to be filed against Tesla, and potentially, the company's subcontractors that helped design and build the Autopilot system.
His comments are inconsistent with Tesla's statement earlier this month, when the company said Model 3 may exceed the growth rate that Ford Motor Co (NYSE:F).exhibited with the Model T.
"We made a decision to revoke Tesla's party status and informed Mr. Musk (Elon Musk, CEO of both SpaceX and Tesla) in a phone call last evening and via lettertoday", he added.
Teslas said it "will be making an official complaint to Congress" about the NTSB.
"We will also be issuing a Freedom of Information Act request to understand the reasoning behind their focus on the safest cars in America while they ignore the cars that are the least safe", Tesla said. Tesla says for every 320 million miles cars equipped with Autopilot drive, there is one fatality, including known pedestrian fatalities.
Tesla cars require drivers to keep their hands on the steering wheel and warn them if they don't.
It's clear that Tesla and the NTSB differ in their view of what comprises public disclosure. The company also noted that the accident occurred at a confusing highway interchange, and the protective shield on the concrete barrier involved in the crash was not in proper condition.
"Tesla explicitly uses data gathered from its vehicles to protect itself, even if it means going after its own customers", said Ramsey, the Gartner analyst. When I visited Tesla's headquarters for a Model S test drive past year, the spokeswoman made a point of walking me through the various safety warnings a driver sees both before and during Autopilot use. They said Walter did not have his hands on the wheel at the time of the crash, despite repeated warnings to take control of the vehicle.
The National Highway Traffic Safety Administration, which has the power to order recalls and fine auto manufacturers, found no defect after investigating the May 2016 crash involving a Tesla Model S driven on Autopilot by Josh Brown, a former Navy SEAL.
"It does happen, but it is rare considering how many investigations we do and how many party members we have", Knudson said.
In a letter sent to Tesla, the agency referred to statements made by the automaker "on or about April 10" regarding the crash.
