THIS IS RELATED TO SUBARU OF AMERICA TSB#09-36-03, NHTSA ACTION NUMBER PE04002. NOT ONLY AM I CONCERNED ABOUT FUEL IGNITION IN ENGINE COMPARTMENT, BUT STUDIES ALSO SHOW THAT GASOLINE FUMES ARE CARCINOGENIC. THIS HAS BEEN A PROBLEM SINCE I OWNED THE VEHICLE IN JUNE OF 2001, HAS BEEN OCCURRING EVER SINCE. FINALLY I'VE HAD ENOUGH OF "DEALING WITH IT". DEALERSHIPS HAVE LOOKED AT MY CAR AND TOLD ME THAT NOTHING IS WRONG, AND I'VE HAD ENOUGH. THIS IS DANGEROUS. *TR

I PURCHASED MY 2002 SUBARU IN OCTOBER OF 2001. THE FOLLOWING WINTER DURING A PARTICULARLY COLD TRIP TO THE MOUNTAINS I NOTICED A STRONG FUEL SMELL OUTSIDE THE VEHICLE. I WAS UNABLE TO REPLICATE IT ONCE I GOT HOME. WHEN I ASKED THE DEALERSHIP GRESHAM NISSAN SUBARU IN GRESHAM OREGON ABOUT IT AT MY NEXT OIL CHANGE THEY SAID THEY DIDN?T FIND ANYTHING. I DID NOT TAKE THE CAR INTO COLD WEATHER AGAIN UNTIL THE VEHICLE WAS WELL OUT OF WARRANTY. WHEN I DID I NOTICED AN EVEN STRONGER SMELL OF GAS. I DECIDED TO PAY OUT OF POCKET TO HAVE THE LEAKING FUEL INJECTION SYSTEM CORRECTED BEFORE I MADE A MOVE FROM PORTLAND OREGON TO THE SIGNIFICANTLY COLDER CLIMATE IN MADISON WISCONSIN. IT WAS VERY DISAPPOINTING TO PAY ALMOST ONE THOUSAND DOLLARS TO CORRECT A DEFECT THAT WAS INHERENT IN THE VEHICLE FROM THE TIME IT WAS NEW. ESPECIALLY WHEN THIS DEFECT MAY CAUSE AN EXPLOSION. *TR

I CALLED MY DEALER AND WAS TOLD THEY KNEW WHAT IT WAS, AND THAT THERE IS A TSB TO FIX THE FUEL LINE LEAK. WAS ALSO TOLD THAT SUBARU DID NOT THINK IT WAS A SAFETY ISSUE SO WOULD NOT COVER IT OUTSIDE OF WARRANTY AND WANTED $600 TO FIX! THIS IS MOST DEFINITELY A SAFETY ISSUE!

THE DESIGN OF THE FUEL LINE (METAL RAIL/RUBBER HOSE INTERFACE) IS SUSCEPTIBLE TO FUEL ODOR AND/OR SEEPAGE IN EXTREME COLD TEMPERATURE CONDITIONS.OWNERS MOST OFTEN NOTICED FUEL ODOR IN THE OCCUPANT COMPARTMENT AREA DURING INITIAL COLD ENGINE START-UP.ONCE THE ENGINE IS WARMED, THE ODOR/SEEPAGE ISSUE DISSIPATES.FROM SUBARU'S DATA, ODI NOTES THAT THE INCIDENT RATES ARE HIGHER IN STATES WITH COLDER TEMPERATURES.THERE WAS ONE ALLEGATION OF A FIRE INCIDENT IN WHICH THE OWNER HAD REPORTED THAT HE NOTICED FUEL ODOR A FEW DAYS EARLIER, BUT ODI COULD NOT CONFIRM THE ORIGIN OF THE FIRE. TO ADDRESS THIS ISSUE, SUBARU WILL REPLACE THE FUEL LINE WITH A LONGER RUBBER HOSE SEGMENT VERSION/DESIGN ON 5,724 MY 2002-2003 VEHICLES BUILT THROUGH SEPTEMBER 12, 2002 IN 16 STATES (AK, CO, IA, ID, ME, MI, MN, MT, ND, NE, NH, NY, SD, VT, WI & WY).IN ADDITION, SUBARU WILL EXTEND THE WARRANTY COVERAGE TO 12 YEARS/UNLIMITED MILEAGE ON VEHICLES IN THE REMAINING 34 STATES.THIS ENGINEERING ANALYSIS IS CLOSED (SEE RECALL CAMPAIGN 09V-468)

Status: closed (inferred from source dates) · Fuel System, Gasoline; Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings
SUBARU REPORTS THAT THE FUEL ODOR IS CAUSED BY FUEL SEEPAGE DURING COLD START OF THE ENGINE UNDER EXTREMELY COLD TEMPERATURES. THE LEAK OCCURS IN A FUEL LINE IN THE ENGINE COMPARTMENT.IT REPORTS THAT THE FAILURE IS DUE TO THE MISALIGNED ANGLE BETWEEN TWO FUEL DELIVERY LINES WHICH RESULTED IN SUCH FUEL SEEPAGE DURING THE FIRST FEW SECONDS OF COLD ENGINE START DURING THESE COLD TEMPERATURES.SUBARU REPORTS THAT THE TWO FUEL LINES ARE CONNECTED WITH A HOSE THAT BECOMES TOO STIFF IN VERY COLD TEMPERATURES TO CONFORM TO THE MISALIGNMENT. SUBARU HAS ISSUED A TECHNICAL SERVICE BULLETIN (SUBARU SERVICE BULLETIN NUMBER 09-36-03) TO REPLACE THE FUEL LINES WITH NEW LINES THAT ARE PROPERLY ALIGNED AND THAT HAVE A LONGER CONNECTING HOSE.ODI PHONE CALLS TO MANY OF THE COMPLAINANTS CONFIRM THAT FUEL ODOR IS NOTICABLE DURING VERY COLD TEMPERATURES AND COLD START BUT GOES AWAY AS THE ENGINE WARMS UP, AND THE ODOR IS NOT PRESENT IN WARMER TEMPERATURES. A FEW OWNERS REPORT THAT ATTEMPTS TO ELIMINATE THE LEAKAGE BY TIGHTENING THE CONNECTING HOSE CLAMPS IS NOT EFFECTIVE IN ELIMINATING THE FUEL ODOR.A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.
