Tesla Motors said Thursday that fire incidents involving its vehicles were 11 times lower than the average for all U.S. vehicles.

The electric car maker said its rate of vehicle fires per 1 billion miles driven was 0.09, compared with the U.S. average of 1.01.

"To put this in perspective, you are more than 11 times less likely to experience a vehicle fire in a Tesla than the average gasoline car," the company said in a blog post.

Tesla's comments come after two recent incidents in which its Model S vehicles caught fire. In one case, a vehicle caught fire after hitting a piece of metal on the highway. In the other, a vehicle burst into flames while parked in a garage.

No one was injured in either incident.

Tesla said it is investigating the cause of the garage fire and has not yet determined whether it was caused by the vehicle or the charger.

The company said it is working with authorities to investigate the highway fire.

"We have been in touch with the driver, who was not injured and believes the car saved his life," Tesla said.

Tesla said it is constantly improving its vehicles to make them safer.

"It is important to note that Tesla's record on vehicle fires is significantly better than the average for gasoline cars," the company said.
