The fuel evap tube on the top of the fuel tank which is located between the tank and the floor pan broke off due to bad mold. This is a plastic tank. If you google it you will see 1000s of Jeep owners are complaining. I asked for warranty on this but dealer refused. this Jeep has always been serviced at Crown Dodge in Ventura Ca. It has never been taken off road. It is a known issue that Jeep needs to reimburse owners for repairs.
