This is the third fire in under a two-month period

The National Highway Traffic Safety Administration (NHTSA) has decided to look into the latest fire involving Tesla Motors' Model S. 

According to The Detroit News, NHTSA will review what is now the third Model S to catch fire in under a two-month period. This most recent incident took place near Smyrna, Tennessee. 

The Tennessee fire took place when a Model S driver hit a tow hitch on Interstate 24, which damaged the car’s undercarriage and caused a fire. The driver was able to exit the vehicle safely.

“NHTSA is in close communication with Tesla and local authorities gathering information about the incident to determine if additional action is necessary,” said NHTSA.

Special focus is being placed on the fact that the Model S' battery is located near the underside, making the battery an easy target when striking debris or hitting pavement -- thus increasing the risk of a fire.

This could lead to stronger methods of protecting the EV's battery pack. 

NHTSA has not opened a formal investigation on the Tesla crashes yet, likely because this is the first incident it's addressing.

But this isn't the first Tesla fire to occur. In early October, a Model S driver in Kent, Washington was traveling southbound on state Route 167 when he hit a piece of metal debris on the freeway. He then exited the freeway, and the car became disabled right before he smelled something burning. The car caught fire.
 
Tesla spokeswoman Liz Jarvis-Shean said the fire was caused by a large metallic object hitting one of the battery pack’s modules. NHTSA did not investigate the fire at the time because of the partial government shutdown, which suspended such activity. 

Another Model S fire occurred shortly after in Mexico, but that's out of NHTSA's jurisdiction. 

Tesla said all three fires were caused by crashes; not spontaneous events.

Tesla and its Model S have been in the spotlight a lot this year after the company successfully paid off its government loans nine years early, pulled a profit, unveiled new tech for its electric car and the Model S even snagged the highest safety rating from the NHTSA. But it's unclear if this hiccup will further heighten the fear surrounding lithium ion batteries for cars, and possibly even take a toll on Model S sales.

Mmmm... I've heard about 3 reports of Teslas catching fire.

That includes both Roadsters and Model Ss.

Roadsters have ~3 years on the road for a rough average of 6,000 auto-years

Model Ss have accumulated around 10,000 auto-years.

3/16,000 auto years ~ 2 per 10,000 auto years (rounded up)

There are roughly 150,000 auto fire a year per ~250 million cars or ~6 per 10,000 auto years.

Seems we have a ways to go. However, many of those 250 million cars are significantly older and potentially poorly maintained. All Teslas should be new and have no significant maintainence issues.

I'd say that the need to add a more substaintial skid plate/energy absorber for the front undercarriage. Several Model Ss and Roadsters have crashed without fire. Simple fix.

Your use of a 1 month sample, monthly rate is silly. For months Tesla had a "zero" rate.
