Tank Filler Pipe And Cap problems of the 2008 Jeep Liberty

Check engine light come on and gas cap light also come on the auto start will not work & dash light gets real dime also gps light get real dime/ and there is a real strong smell of gas that comes inside the vehicle while going down the road. The vehicle has been to 4 difference Chrysler dealer ship and computer has been replaced sensor have all been replaced gas tank replaced gas cap replaced . This vehicle has been for these problem 11 times and has never been fixed called Chrysler customer service 6 different times all we get is the run around . The dealer ships drive the vehicle and have put 1,500 mile on the vehicle driving it. Need some know to why this can not be fixed.

The fuel spills out of the tank when fueling the car resulting in gas on the vehicle and ground of the gas station. This has been going on for about two months. I have taken it to the dealer who said it needed a fuel vapor filter replaced. This did not fix the problem and now the dealer states I need a new gas tank. Since this is a non-maintainable part I feel it is a mfr. Defect and a very unsafe one at that.
