What 2004 Subaru Impreza owners say
Fuel & propulsion system all 37 →
The contact owns a 2004 Subaru Impreza. The contact stated that while driving at 65 MPH, the vehicle stalled, and the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with an unknown code for the throttle body. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 162,000.
Rubber fuel lines under the intake manifold leak fuel when the temperature falls below 40 degrees F. The smell permeates the cabin and fuel can be seen wetting nearby surfaces under the intake. An inspection can be performed. This represents a fire safety hazard that could occur while the vehicle is in motion, jeopardizing all surrounding traffic. The problem is widely noted on Subaru internet forums, but only a recall for 2002-2003 models has been reported. My car is a very early 2004, so it shares traits of the 2003 engines. There are no warning lamps or notifications, only the smell of raw gas when the car starts and is in motion in winter temperatures. This has happened repeatedly since the issue first occurred, so I avoid driving this vehicle if at all possible.
Suspension
The contact owns a 2004 Subaru Impreza. The contact stated while driving 60 MPH and hard braking, the vehicle started shuddering violently and the steering wheel was not operating as needed.

I have already visited my local Subaru dealer to remedy this recall. I have a physical invoice as proof that my vehicle was inspected & already has the correct air bag installed. I have called the recall line [phone]) MANY times & no matter who I speak to the recall does not clear despite me informing them I have already completed the repair. All representatives say the same thing claiming they will "take care of it or speak to a manager" & telling me to wait so it clears on its own over time. It has now been almost 2 years since my visit & I am still receiving an excessive amount of notices. The vehicle works as it should 100% with no issues.
