Actor Mary McCormack has shared video of her husband’s Tesla car catching fire while in traffic in California. Flames can be seen shooting out from underneath the vehicle as it sits on the side of the road.

McCormack said in an accompanying tweet it was not the result of an accident and that the incident came “out of the blue”.

Sheriff’s Lieutenant William Nash in West Hollywood confirmed on Saturday that deputies saw smoke coming from the electric vehicle and then fire.

Deputies requested help from firefighters who quickly extinguished the flames.

Tesla called the incident “an extraordinarily unusual occurrence” and said it was investigating.

Nash said the driver, who was not named in a log entry, had got out of the car and that there were no injuries. Nash said the log entry cited the possibility of a faulty battery.

Representatives for McCormack did not immediately return a message on Saturday seeking comment. She is married to director Michael Morris.
