After three hours of waiting the service tech, Chantell Kirby [XXX], informed me that I needed a fuel pump and tank and the cost would be $6,184.94.

I was sold a vehicle by a dealership with a busted gas tank. It appears to have been an attempt to repair it with patching material. I am unsure if the defect was a result of manufacturing versus acquired damage. My safety is at risk because of leaking gas that could potentially ignite and inhaling strong gas fumes that could impact my lungs and health. The fuel tank damage has been confirmed by a mechanic and documented. It has not been inspected by any other entity while in my possession other than reported inspection by the dealership. I secured the vehicle on [XXX] from the dealership with these safety concerns. A mechanic stated the damage could have resulted either with the dealership or during on and off the trailer during transport of the vehicle from Florida to Indiana.
