- The problem
- On certain passenger and sport utility vehicles, the cover bolts for the engine oil control valve may not be sufficiently tightened, allowing oil to leak from around the cover gasket.
- The risk
- If leaking oil contacts components operating at high temperatures, a fire could result in the engine compartment.
- The fix
- Dealers will inspect and retighten the oil-flow control valve cover bolts. The recall began on october 8, 2004. Owners should contact subaru at 1-800-782-2783.

Engine recalls for the 2004 Subaru Impreza
Engine complaints
Upon starting the car during the colder winter months, a raw fuel smell will begin to fill the cabin if the hvac system is turned on to vent fresh air. This smell is strong enough to cause lightheadedness and the sensation of nausea. Upon further investigation, the passenger side fuel line is leaking fuel underneath the intake manifold, to the extent that you can visibly see a puddle of fuel boiling on top of the engine block. This happens because there are two hard metal fuel lines running to the fuel injectors...

connected by a small piece of rubber hose with clamps. However this hose from the factory is cut too short, so when the temperature is cold enough the rubber looses its elastic properties and as the metal lines vibrate / move with the motor, it leaks fuel out of the rubber hose. This problem has been addressed by subaru in the tsb #09-36-03. They offer to replace the rubber hose and hard metal fuel line for model years 2002 and 2003 impreza wrx's free of charge. Having been an owner of a 2002 impreza wrx before purchasing my 2004 impreza wrx, I had this service performed at my local subaru dealership. I am disgusted to find out that this coverage does not apply to the model year 2004 impreza wrx, when it features an identical motor and drivetrain to the previous years (2002, 2003.) This means that the fueling system is identical as well, and that the previously acknowledged raw fuel leak is happening in my car as well. The fact that the 2004 impreza wrx has the same motor. And same fuel system, and subaru of america will openly deny coverage to have the parts replaced is truly disgusting in itself. Raw fuel leaking on top of a hot engine block, around sources of ignition is the most extreme of safety hazards, and now I own a vehicle in which I cannot transport my wife and child. I am truly disappointed in subaru for turning a cold shoulder to this. *Tr
Started as an unusually high idle while in park (as soon as the car was turned on). After a few hours of running it (driving 48 mi to work and errands), I would put the car into drive & as soon as I would remove my foot from the brake (already having a high idle) it would accelerate on it's own to 15-20 mph. When I would brake and bring the car to a full stop, it would "jump" slightly against the brake. Finally I noticed the gas pedal felt as if it was not moving smoothly. As I took the car off of cruise control...

(at 65 mph) by turning it off at the cc controls on the wheel (my feet not near the pedals) it began to accelerate rather than slow down. At this point I parked the car & called for a tow to the subaru service center. *Tr
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. *Tr

The "check engine" light has come on 7 times since the vehicle was purchased new in january 2004. The first two times I was told by the dealership (valley dodge, inc.) That it was a false code (#p0301) for a 1st cylinder miss fire. On the third time the "check engine" light came on, the dealership removed the ecm and sent to the subaru of america, inc. Factory to reprogram. The fourth time the dealership, per subaru of america, inc. Factory, adjusted the #1 cylinder exhaust valve. The fifth and sixth time, the...

dealership per subaru of america, inc. Replaced the injection and still have the car to beta test on a 100-mile 'test drive' as I was told to compare the read-outs from the ecm during this 'test-drive.' I have been without the vehicle for 20 days non-consecutive in the 6 months that I have owned the vehicle. *La
