The National Highway Traffic Safety Administration has begun investigating 2010 Jeep Wrangler models after receiving eight reports of engine bay fires.

According to the complaints, seven of the eight 2010 Jeep Wranglers were running when the fires began. In August 2009, the NHTSA began investigating the SUV after three Wranglers reportedly caught on fire. Chrysler recalled the Wrangler in February 2010 citing overheated transmission fluid in the four-speed automatic that could leak onto hot surfaces and possibly ignite. Extreme off-road driving increased the risk. The four-speed automatic was replaced in 2012 with a five-speed.

One driver complaint noted the appearance of "an unknown liquid burning down to the ground from the engine area," but despite attempts to extinguish the fire with water, the Jeep was a total loss within minutes.

Chrysler is cooperating with the NHTSA.

"Vehicle fires are very complex and can occur for a number of reasons that have nothing to do with the vehicle itself," Chrysler spokesman Nick Cappa told Automotive News. "Poor maintenance, improper vehicle use, or installation of after-market equipment often are causes of vehicle fires."

No injuries or deaths stemming from the fires have been reported.
