“Only on cold days I smell fuel while driving, upon investagation I found that the little rubber lines under the intake were leaking fuel on to the top of the engine. I called Subaru and they said the they know about the problem but my car is not in the recall becauase I don;t live in the affected states so if I move to newyork or michigan I would be covered well I like ohio so if this could get expanded that would be great.”

“It has recently been extremely cold in chicago and upon initial startup of the vehicle there is a strong smell of gasoline inside the cabin. The smell does not go away until the car is completely warmed up. I noticed that there has been a recall for this type of problem. It was Subaru recall no. Wvk-21. I believe my car should fall under this recall. I called Subaru customer service and they told me that my car did not fall under this recall campaign. But the problems I've been having fit the description of the recall campaign.”

“This is regarding a 2003 Subaru Impreza wrx. I am experiencing the fuel leak addressed in NHTSA action number : pe04002. I am located in albuquerque, new mexico. Recently I have had the car outside in temperatures as low as 30 f (nights are spent in a garage next to a furnace--probably 40 f). I am having the fuel leak that you and Subaru of america claim occurs at only extremely low temperatures. I have had it occur three times, and both times the fuel smell persisted after 15 minutes of driving, even with windows open. …”

“For a couple of years in cold weather, usually below 32 degrees, the smell of gasoline existed in the cabin of the vehicle. I had it checked during an local state inspection and discovered fuel was leaking on the passenger side of the engine compartment. It was discovered that the manufacturer was aware of this. I contacted three(3) local dealers, that all new about TSB 09-36-03. They all quoted the same $500 estimate to repair. Two of the dealers, Subaru of dallas and huffines Subaru in dallas texas informed me that failure to correct the condition could result in an engine fire. …”

NHTSA complaint #10183290, filed 2007-02, 25,000 miles

“I have a cold weather fuel leak underneath the intake manifold. This fuel leak causes the cabin of the car to fill up with volatile fumes. It is a visible leak and drips on top of the engine near sources of ignition. I contacted Subaru of america and 3 of my local dealerships and they have acknowledged the problem but only rank it as a service bulletin not a recall. This problem exists with all Subaru wrx owners in a cold climate. Use a search engine on the internet for (cold weather fuel leak wrx ect..) and you will find thousands of affected owners. Subaru wants $500-$900 for the repair. …”
