Federal safety regulators opened a probe into a series of fires in Tesla Motors Inc. electric cars involving the battery casings, including one that burst into flames on Highway 167 near Kent Oct. 1.

TESLA ON FIREThe National Highway Traffic Safety Administration said Tuesday that it would investigate why two of the expensive Tesla Model S sporty hatchbacks have caught fire this year following accidents in which the battery casing that serves as the undercarriage of the car cracked open.

A third fire, which took place in Mexico, won’t be part of the investigation because it is outside the agency’s jurisdiction.

NHTSA noted that in the two U.S. fires, one near Seattle and the other in Nashville, the battery monitoring system in the cars warned the drivers, allowing them to pull over and safely exit the vehicles before the battery emitted smoke and fire.

The fires have become an issue for Tesla, contributing to 37% drop in the value of its stock since reaching a high of $193.37 on Sept. 30.  The shares were down an additional 2% in overnight trading Tuesday.

Tesla Chief Executive Elon Musk said the automaker requested the investigation to refute fears that electric cars are more prone to fires than other vehicles.

But the NHTSA disputed that, saying its decision was an independent process.

“In regards to Tesla, the agency notified the automaker of its plans to open a formal investigation and requested their cooperation,” the agency said, “which is standard agency practice for all investigations.”

Tesla is already taking action, changing its warranty to cover damage due to a fire, even if due to driver error.

“Either our belief in the safety of our car is correct and this is a minor cost,” Musk said, “or we are wrong, in which case the right thing is for Tesla to bear the cost rather than the car buyer.”

The automaker believes the warranty change, which doesn’t apply if an owner purposefully sets the car on fire, will reassure buyers.

“If a false perception about the safety of electric cars is allowed to linger, it will delay the advent of sustainable transport and increase the risk of global climate change,” Musk wrote in a post to his blog on the Tesla website Monday night.

The automaker is taking advantage of the car’s electronic capabilities to execute a wireless update to the air suspension that will result in greater ground clearance at highway speeds, Musk said.

“This is about reducing the chances of underbody impact damage, not improving safety,” Musk said. “The theoretical probability of a fire injury is already vanishingly small and the actual number to date is zero.”

Another software update expected in January will give the driver direct control of the air suspension ride height transitions.

Musk also defended the automaker’s vehicles, writing that they have a lower fire risk than gasoline vehicles.

“Since the Model S went into production mid last year, there have been over 400 deaths and 1,200 serious injuries in the United States alone due to gasoline car fires, compared to zero deaths and zero injuries due to Tesla fires anywhere in the world,” Musk wrote.

TACOMA — Ever since a Tesla burst into flames along Hghway 167 earlier this week, everyone’s talking about the safety of electric cars.

Fire crews in Kent had some trouble putting it out, and our questions about it led us to Pierce County’s fire training facility. New recruits at Central Pierce Fire & Rescue spent Friday afternoon attacking a dummy car spilling with flames.

“It gives them that realization of how to put out a car fire,” said CPFR Capt. Woody Juarez.

firetrainingCar fire training is at the top of the list since an all-electric car went up alongside the highway after it struck a metal rod on the pavement. The driver of the Tesla was able to pull over before the flames erupted. No one was injured.

Gas-powered, hybrid or electric — all car fires present a special set of challenges.

“There’s a lot more plastic, they burn a lot faster,” said Juarez. “It’s not like looking at a 1972 Buick that just didn’t burn that much. It burned, just not a quickly or as fast.”

For instance, lightweight plastics and other new materials used to build the latest models ignite faster than old steel panels.

“It’s constantly changing,” said Jeff Pugh with the Puyallup Extrication Team. “The coming of the new vehicles, the hybrids and electric vehicles, you bet it’s a huge learning curve.”

The Tesla fire was a first for Kent Fire & Rescue and the incident caught the attention of fire departments across the country.

Usually a combination of water and foam is the best way to put out a vehicle fire but it depends on the type of material that’s burning, said firefighters. Plus, the chemicals in hybrid and electric batteries are a new twist for firefighters.

Either way, Pugh said, a fire is still a fire.

“Whether it’s a battery pack burning or the parts of the car burning, it doesn’t matter,” said Pugh. “You’ve gotta cool it and take the oxygen away.”

Tesla’s CEO posted a message on his company’s blog on Friday saying electric cars are safer in a fire because they don’t have a big tank of gasoline inside.

And as for the firefighters, they continue to learn from experiences like the Tesla fire; they’ll add that knowledge and new techniques to training as things change.
