To whom it May concern, hello, I am the owner of a 2004 Forester xt which I love. I've owned the car for almost a year and its been nothing but reliable up to this point. The weather outside is frightful, and with that comes a common problem for many Subaru owners. During the cold snaps, say below 20f, there is strong fuel smells which fills the cabin. It only happens during start-up, and lasts about 15 mins before the car warms up. From searching many forums and internet threads it seems this problem has been occurring since early 2001. There was a recall notice (wvk-21)for the 2002 -2003 wrx's which had a same problem I am experiencing now. Unfortunately a recall was never issued for later model subarus which suffer the same problem. The problem is fuel leaking from 5 main fuel lines going into the intake manifold. …

Engine compartment fire, resulting from oil leaking in engine compartment. There were no injuries and because of proximity of fire department fire was extinguished within 4-5 minutes. Subaru of America (soa) maintains that oil leaked from oil filter and that this is no fault of theirs. Given the history of recalls of this type of vehicle in Japan for leaking oil and fires I am not sure that this point has been demonstrated. Soa refused to fix damage and told me to file an insurance claim... Which I have done. Damage is estimated to be $6-10K. Matter will be subrogated to insurance company for settlement.

Car producing noxious odor inside. When parking car in garage, accidentally stepped on accelerator rather than brake. Hit and destroyed back wall. Cosmetic damage to car. Dealer claims leaves were sucked into the engine compartment through turbocharge intake. But, odor was of burnt rubber or plastic, not leaves. And, the car is always parked in the garage. Finally, most leaves were down several weeks earlier this year, I.e., by end of November.

I purchased a 2004 Subaru forrester xt in February of '09 with 93,008 miles on it. The dealership had all service records relating to the vehicles history, and all guidelines were followed according to the manufacturer's specifications. The current mileage on the vehicle is 102,323 and I was just informed that the turbocharger is coming apart and needs replaced or the vehicle will be non-operational. I contacted Subaru of north America and they informed me that there was nothing that they could do, which I understand. My main problem is that the representative that I talked to informed me that the manufacturer changed its guidelines for later models of the vehicle to a shorter recommended interval between services. These models have the same engine and turbocharger as my vehicle and they changed the scheduled maintenance from 7,500 miles to 3,500 miles. …

Strong fuel odor inside cabin developed when operating on cold mornings; fuel odor typically went away within 15 minutes of starting the car. Inspection of fuel lines, filter, etc. Revealed no obvious leaks above the intake manifold. Dealer quoted approximately $800 to remove intake manifold and inspect. I have had two independent shops attempt to fix this issue over the past 3 years with varying degrees of success; the most recent (2011) removed the intake manifold and replaced all rubber fuel lines under the manifold, but the problem has recurred this fall and winter and at increasingly warm temperatures. Now, there is a visible and obvious leak from a fuel line just as it goes under the manifold--inaccessible without removing the manifold. …
