Temp outside wont necessarily keep the smell of gas fumes from coming... colder temps = more concentrated fuel for motor to run = less fuel burned = gas fumes from heat of exhaust... although once your car warms up, the fume smell should go away.

You shouldn't be smelling any gas in the cabin. Something is leaking and the fumes are coming in the cowl at the base of the windshield. Look at the connections where the rubber lines meet the steel lines from the tank. If it's small, it might not look wet but it will be stained.

It is likely that your gasoline filler tube has rusted and is beginning to seep gasoline when you refuel. You would first start noticing this only when you fillup past the level of the fuel tank.

I have noticed it the past couple of years and it only happens with the cold temps. When temperature gets warmer I do not smell it and it happens whether I have a full tank or empty tank

Look at the little hose to the left of your pass. side spark plugs connectors on the top of the engine , it will be under a bracket that is where it usually leaks from when the weather is cold the metal contracts and leaves a little gap where it goes into the hose, I replace the OEM clamps with some hose clamps and it is fine , you can always try tighting the oem clamps . It is a lot easer to take off the bracket so you can get at the hose good luck

I had this problem wiht my 2002 Outback last winter in the polar vortex weather. The fix was simply to tighten the little clamps on the fuel lines, the cold has caused the metal in the clamps to shrink and that made them loose. Once the guy at the garage took a tiny screwdriver and tightened then all up again, there was no smell.

https://www.facebook.com/MakeSubaruOfAmericaFixTheirFuelLeaks This is a common problem that Subaru recalled for the 2002-2003 Subaru WRX only (and only in cold certain cold weather states). Unfortunately they have failed to issue a recall on any of their other models...even though many of them are also affected.

Best take it in to a shop. When cold weather occurs, things contract with temperature. As the engine warms, things expand. Best to have a certified technician look the whole system over for leaks just to be safe.
