The U.S. National Transportation Safety Board is opening an investigation into a Tesla Inc. crash near Mountain View, Calif.
The car hit a barrier March 23 and caught fire, Bloomberg News reported March 27.
The NTSB said in a tweet that it is sending two investigators to examine the post-crash fire and steps needed for a safe removal of the vehicle from the accident scene.
It is "unclear" whether Tesla's automated control system, known as Autopilot, was engaged at the time of the crash, the safety board said.
"We have been deeply saddened by this accident, and we have offered our full cooperation to authorities as we work to establish the facts of the incident," Tesla told Bloomberg in an emailed statement.
The agency is also investigating a Jan. 22 accident in Los Angeles in which a Tesla Model S crashed into a fire truck on a freeway, the news outlet reported. The driver of the car said he had the vehicle's Autopilot engaged at the time of the accident.
