Mary McCormack, the "West Wing" star, shared a video of her husband's Tesla vehicle on fire on Friday afternoon.
"This is what happened to my husband and his car today," she wrote on Twitter.
"No accident, out of the blue, in traffic on Santa Monica Boulevard. Thank you to the kind couple who flagged him down and told him to pull over. And thank god my three little girls weren’t in the car with him."
McCormack has been married to director Michael Morris since 2003.
Tesla said in a statement that they're investigating the fire.
"We offer our support to local authorities and are glad our customer is safe," a spokesperson told The Daily Mail. "This is an extraordinarily unusual occurrence, and we are investigating the incident to find out what happened."
Sheriff’s Lt. William Nash in West Hollywood told The Associated Press that deputies responding to the scene saw smoke coming out of the vehicle, then fire. Firefighters arrived and quickly extinguished the flames.
Nash said the log entry cited the possibility of a faulty battery as the cause of the fire.
Elektric, an alternative news website, reported that a number of incidents have come to light recently involving Tesla vehicles catching fire after crashes, noting the difference, in this case, is that no crash occurred.
The website said the fire happened because the battery pack was punctured, possibly because Morris had run over something without knowing.
"It is reminiscent of a few instances of Model S battery packs being punctured by objects on the highway which led to fires," Elektric writer Frederic Lambert said.
"Tesla ended up adding a new underbody plate to the vehicle to fix the issue. Now I am not saying that it’s impossible that it caught on fire on its own either. In 2016, a Tesla Model S caught on fire during a test drive event in France without any impact. The automaker eventually determined that the fire was due to ‘electrical connection improperly tightened’ by a human instead of robots."
