I've noticed a severe gasoline smell (inside and outside) and vehicle will stall at times when starting the car, so we took it a dealer for diagnostic and get it fixed. They found left fuel sending unit was leaking from a plastic weld. It seems little odd to have this types of issues at a such young age of the car.
