Owner report 11567144 · 2024-01-23 (January 23, 2024)
I have been noticing intermittent gasoline smell outside of vehicle. It has been smelling stronger and more often so I decided to inspect it for the second. I removed the carpet and fuel pump cover and discovered the fuel pump is leaking gas. Now I cannot drive vehicle due to gasoline leaking every time the ignition is on. It is a serious safety and fire hazard. I have not contacted the dealer because it is not under warranty.
