Following a story by Local 2 Investigates, the National Highway Transportation Safety Administration has expanded its investigation into Jeep Wrangler fires.
The NHTSA has asked Chrysler Group for information, documents and video pertaining to fires in 2007 to 2012 Jeep Wranglers.
The government has logged 23 total complaints.
A spokesman for Jeep said the request is routine and the focus of the investigation is on the 2010 model.
NHTSA confirmed that requesting information pertaining to other model years is standard practice and the focus of their probe is on the 2010 Jeep Wrangler, at this point.
Chrysler Group stressed the action is not a recall and should not be linked to a recent engine compartment fire in Houston involving a 2012 Jeep Wrangler.
"Six o'clock in the evening, I go out and I see smoke coming from the parking garage. I'm like, 'Oh, I feel bad for that guy.' I turn the corner -- there is my Jeep, just a blaze of glory," Jeep owner Mike Embry said.
Embry had purchased the Jeep from River Oaks Chrysler Jeep Dodge just hours earlier.
A Houston Fire Department report cited "failure of equipment" with "electrical arcing" of components not identified as the cause of Embry's Jeep fire.
