“As my wife and I were filling up our 98 Subaru legacy Outback we noticed a smell of gas fumes on the way home as I backed the car into the driveway I noticed the smell of fuel even stonger. I went to the back and looked under the right rear and to my surprise the fuel filler neck was leaking fuel!! I placed a oil change pan underneath and to this day I still haven't fixed it. Don't know were to begin with it and I'm thinking it's a design flaw seems like there is heavy corrosion on the very low part of the filler pipe and that's were it's leaking from. …”

“Fuel (gasoline) filler neck for the 1998 Subaru legacy wagon rusts out. Mechanic indicated very common problem with this year make and model. Very poor design because the tube is behind a plastic molding that accumulates dirt, salt, water, and rots the tubing causing a chronic leak of gasoline potentially over the exhaust system. Recall and repair is needed.”

NHTSA complaint #10354455, filed 2010-09, 166,000 miles

“The gas fill pipe leaks gasoline. There is a plastic shield next to it that catches dirt, sand, etc and then keeps the outside of the pipe wet for weeks after any rainy drive. This LED to the pipe rusting out and leaking gasoline on the road, driveway and garage.”

NHTSA complaint #10160592, filed 2006-06, 109,000 miles

“The contact owns a 1998 Subaru Outback. Since october of 2007, the contact smelled fuel inside the passenger compartment. He took the vehicle to the dealer for a diagnosis and they stated that the failure was due to the fuel metal nose. The nose corroded and caused fuel to leak. The dealer will replace the nose metal at the cost of $278. The manufacturer stated that the vehicle was out of warranty; therefore, they would not assist with the repair. The failure mileage was 122,000 and current mileage was 124,000.”
