2007 Jeep Liberty fuel system problems

The 2007 jeep liberty sport my parents and 3 year old child were in was t-boned on the passenger side by another car that was traveling at approx. 45 MPH upon impact, resulting in the jeep rolling over several times. The other car struck the jeep directly in the middle, causing the middle section to cave in, forcing the passenger seat into the dash/glove compartment. The rear axle on the passenger side separated from the frame, the drive-train separated, the gas tank ruptured, and the rear shock springs came off.

Almost every time I fill-up, there is a splash-back from the fuel filler opening. This apparently is a very common problem with the liberty model among others. I spoke with the service department at the dealership and was told that I would need to pay for any repairs since there was no recall that would pay for it. I then contacted chrysler who told me that my specific liberty is not part of any recall or TSB so they cannot help. I believe this problem poses a hazard if the gas was to ignite.
