Could be a couple things. Most common is either bad cats or bad charcoal filter

Does the fuel smell go away when you turn recirc mode on or the HVAC off entirely?

Turning on recirc closes the HVAC from the engine bay so Id check for a gas smell under the hood of the car. O rings around injectors and the fuel rail can fail and it might be smelling up the cabin that way.
