(WHAS11) -- The safety of the most popular SUV's on the roads is being questioned. There is an investigation into certain Jeeps to see if they run a greater risk of starting a deadly fire.
Safety advocates warn that a rear-end crash into Jeeps made between 1993 and 2007 could rupture a plastic fuel tank located behind the rear axle.
The government says 15 people have died in these crashes.
Chrysler insists its SUV safety records in rear collisions are as good as other car makers and that no recall is necessary.
Safety advocates say installing a shield around the gas tank would fix the problem and cost Chrysler no more than $100 per vehicle.
