There is growing concern as the number of Kia vehicles bursting into flames continues to climb in areas of Florida.
Scripps station WFTS in Tampa first exposed the spontaneous fires in April.
WFTS is now asking federal regulators why they aren't doing more and what it will take to get answers from the manufacturer.
On a 911 call, a witness described a baby being pulled out of a burning sport-utility vehicle on the side of Highway 27 in Polk County.
Daniel Adams, his wife Christina and their 13-month-old son were all inside the Kia when it caught fire last month.
The Davenport, Florida, couple said they escaped from the vehicle with their son with seconds to spare before flames engulfed the entire 2013 Sorento.
Tisha Van Allen said her 2012 Optima spontaneously burst into flames while she drove down the road in Memphis weeks ago. Van Allen is the second Optima fire victim to tell us she could not get the door open. In her case, a passerby stopped and yanked her door open.
Hundreds of KIA drivers around the country have filed similar reports with the National Highway Transportation Safety Administration. But two models stand out.
Ninety-one of the complaints involve the 2011 to 2014 Optimas and Sorentos. Many of these vehicles were already under an engine defect recall unrelated to the fires.
Weeks before the fire, Kia replaced the engine in the Adams' Sorento under the recall. WFTS spoke with nine KIA drivers who said their vehicle burned to the ground.
To put the fires into perspective, WFTS looked at similar-sized SUVs and sedans. Over a three-year period Ford, Toyota and Honda SUVs reported between one and two fires each. NHTSA data for the 2013 Toyota Camry and Honda Accord contains a total of two fire reports total.
Auto fire investigator Rich Meier of Meier Fire Investigations examined the Adams’ vehicle.
He determined the fire started in the rear portion of the engine compartment but could not pinpoint the cause. This prompted KIA to examine three of the vehicles in our stories.
Kia said in an email. “Kia Motors America (KMA) works directly with customers and will provide inspection results directly to those customers. If it is determined that a fire is the result of a manufacturing-related issue, KMA will work with customers to address any costs or expenses they may incur.”
Florida Sen. Bill Nelson petitioned NHTSA for a full investigation after seeing one of the WFTS stories, but the agency limited its review to the two recalls already in place.
Consumer watchdogs, including Consumers Union, accuse NHTSA of failing to protect public safety by not separately investigating the fires.
Now, the U.S. Senate Transportation Committee is debating whether to call a Senate hearing that would force the makers of KIA to answer questions under oath about the fires and what's causing them.
