"This is what happened to my husband and his auto today", McCormack said in a post that has since been deleted.
The safety board is investigating four Tesla crashes since previous year and looking at post-crash fire issues and the use of Autopilot.
The footage shows flames shooting up from underneath the auto. "No accident, out of the blue, in traffic on Santa Monica Blvd". Responding to queries on Twitter, McCormack said the Tesla wasn't equipped with Autopilot and that her husband was "barely moving in traffic" at the time.More news: Kim sends note of thanks and flowers to President Xi

"Thank you to the kind couple who flagged him down and told him to pull over", McCormack wrote of her husband, director Michael Morris. He was not injured in the fire.
In May, the NTSB began investigating a crash involving a Model S that killed two teenagers in Florida after it crashed into a wall and burst into flames.
"This is an extraordinarily unusual occurrence, and we are investigating the incident to find out what happened", a Tesla spokesperson told The Drive. McCormack, however, later specified that Morris's vehicle wasn't on Autopilot. Tesla says that based on the size of its fleet and the number of miles it has traveled, a Tesla vehicle is at least 10 times less likely to experience a fire than a gas auto.
The NFPA numbers don't specify how many, if any, of those fires involved electric batteries. Lt. Dan Nagelmann, from the Los Angeles County Sheriff's Department, confirmed it was either a battery or mechanical issue that caused the fire and there was no collision at all.
