2017 Hyundai Santa FE Sport fuel system problems

My 2017 Hyundai Santa Fe had a new engine installed at the dealership, Fred Beans Hyundai Flemington, NJ. I picked it up on [XXX] on [XXX] (and after 134 miles) my car's check engine light came on. I rerouted to dealership about 8 miles. Sitting outside service bay, I smelled smoke and then saw smoke coming out of vents. I then jumped out of car and the car became engulfed in flames and subsequently exploded.

After having recall service completed on gas tank area, ( flvv pump fuel replaced on jan 11th 2018) I noticed after filling the vehicle with fuel to full capacity, a very strong odor of fuel is present on the exterior of the car when I park it inside an enclosed area (garage). This gasoline smell persists until I use 1/8th of the tank by driving. Hyundai dealer service inspected and stated it is a "small leak as a history code and performed evap. Service bay test pass. Actuated purge valve and found it sticking.
