At temperatures of 20 degrees F or below, there is a strong fuel smell when the car is running. Tightening up the fuel hoses/clamps works for a day or two however the smell always comes back. The smell will go away after 30 minutes to 60 minutes of warming up or driving.

Today's date is December 06, 2008. I started to smell a foul gas smell inside my cabin a few days ago. The smell has occurred since then. What seems to trigger the smell of gas is the cold start ups in temperature degrees of low 20's and below. The smell is extreme. It's enough to make sitting driving almost unbearable, my passengers, along with me get headaches. I am forced to open the windows in freezing weather to allow the gas smell to exit. The smell goes away after opening windows and/or 10 or more minutes of vehicle operation. I have only searched for help from the nasioc online community. It is a community of thousands of Subaru owners who as well have reported hundred of cases of the same gas smell.

I was driving down a main road in boston when my engine caught on fire. As a result I ended up crashing into a snow bank. When I reported this to the dealership they said that they would look at the problem and fix it. When the car was inspected it was found to have aftermarket parts that are not D.O.T. legal and no C.a.R.B. id's. all of these modifications were installed prior of me buying this vehicle and it was sold to me with a warrenty. I had complained about a smell of gas and a huge loss of oil before this happened but was told that is how a Subaru Impreza WRX sti runs. Also the dealership got a emmisions sticker for this car when it will not pass emissions with all of the afterarket parts. Nothing has been done to fix this problem and the dealership refuses to take any responsibility for this event.

My 2004 Subaru WRX sti has a fuel odor in the cabin when the car is started in moderately cool temperatures. The problem is described in ODI resume PE 04-002. The manufacturer says the problem occurs in very cold temperatures and stops quickly. I have found that it occurs in moderate temps. Below 50F and lasts for 20 to thirty minutes. I take this to mean that the problem is worsening and could result in ignition of the leaking fuel. This problem occurs in several models of Subaru according to my internet research. The manufacturer has a service bulletin #09-36-03 that describes how to fix the problem but the cost would have to be paid by me. I believe this to be a serious design flaw and that the manufacturer should be required to fix it under a recall.
