WASHINGTON, D.C. -

Consumer-reported fires in a pair of late-model domestic vehicles triggered an investigation by the National Highway Traffic Safety Administration.

Federal officials explained they are examining the 2011 Chevrolet Cruze and 2011 Jeep Wrangler to determine the cause of consumer complaints they have received recently.

The Office of Defects Investigation (ODI) has received two complaints of engine compartment fire in the Cruze. ODI indicated both complaints were received within the last month and allege engulfing fires resulting in total vehicle loss.

In addition, ODI identified field reports submitted as part of Early Warning Reporting data that relate to the alleged defect.

“A preliminary evaluation has been opened to assess the cause, scope and frequency of the alleged defect,” officials stated.

NHTSA also shared a transcript of one complaint it received about the Cruze.

“While driving a 2011 Cruze Eco with approximately 11,000 miles, the car caught fire,” the complaint began. “The car was last serviced by the dealer approximately 4,000 miles ago (three months). The car was 30 miles into a 43-mile trip when it caught fire, and prior to the incident there were no warning signs of any problems with the vehicle.

“The only indication of a problem was slight smoke coming from the engine bay,” the complaint continued. “Then as soon as the car was stopped a flame came out between the hood and the cowl area. The car was totally engulfed within five minutes of stopping, and it was only after the first sign of fire was visible that the warning light on the dash board illuminated.

“The car is a total loss, and Chevrolet has stated they will have someone contact me in seven to 10 days to discuss the incident,” the complaint went on to state. “From research online it appears this is not an isolated incident, and I am concerned as I was never warned via a technical bulletin or recall of any potential issue with this vehicle. Chevrolet has not seemed to be very concerned over this issue thus far, but I am pushing for action from Chevrolet.”

NHTSA noted the Cruze investigation involves an estimated 177,330 units.

Meanwhile in regard to the Wrangler, ODI confirmed it received eight reports alleging fires originating in the engine compartment. Officials indicated seven of the eight complainants allege the fire or symptoms of the impending fire began while driving.

“A preliminary evaluation has been opened to assess the scope, frequency, and safety-related consequences of the alleged defect,” ODI reiterated.

Like in the case with the Cruze, NHTSA shared a transcript of a complaint.

"For the past month after driving for approximately a half an hour or so, I have noticed white smoke coming from the engine compartment sometimes when I stop completely at a stop sign or red light,” the consumer told NHTSA.

“I have noticed this at least eight or nine times,” the consumer continued. “I do take long trips and it is my daily vehicle and now that I have heard about some 2010 Jeep Wrangler models experiencing vehicle fires, I wanted to see if there is anything I can do to ensure my family and my safety as we travel. I appreciate your time in this endeavor and look forward to hearing back from you.”

According to officials, the Wrangler investigation covers approximately 100,000 units.

In a report from Reuters, both General Motors and Chrysler insist they were cooperating with the government and were unaware of any injuries or fatalities stemming from the fires.

“We are conducting our own investigation and will share any findings with the government," GM spokesman Alan Adler told the wire service in an email.

“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 shared with Reuters. “Poor maintenance, improper vehicle use or installation of after-market equipment often are causes of vehicle fires.”
