I have an 04 X and just starting recently, (about 2-3 weeks ago) I have been smelling a slight gasoline smell while inside the car. It is not as strong as the smell when pumping gas but it is pretty apparent that it is a gasoline smell. I have stuck my head under the car near the gas tank and cannot smell anything. I first thought it was some sort of gas leak. Also, I have not been using my heater or AC.

Anyone know what this could be?

 

Bad O ring.!! Maybe..

 

Is it when you first start the car or all the time? Catalytic converters have to warm up and there will be a gas smell till they do. Takes longer when it is cold.

 

yea its when I am first starting up and that makes sense because it is cold here.

Also, I am pretty sure the smell is coming out of the A/C vents.
