TOOK MY VEHICLE IN FOR ROUTINE MAINTENANCE WHEN IT WAS FOUND TO HAVE A SIGNIFICANT GAS LEAK. SPECIFICALLY THE FUEL RAIL HAD SOMETHING LIKE 16 LEAKS. WHILE I NEVER HAD AN ENGINE FIRE THE POSSIBILITY FOR THAT HAPPENING WAS VERY REAL. THIS IS MY FAMILY CAR, WHICH I TRANSPORT MY CHILDREN IN. FROM READING OTHER EXPERIENCES ABOUT THIS I HAVE FOUND IT TO BE A FLAW IN DESIGN WITH THE 2003 SUBARU WRX. I WOULD HOPE THAT SUBARU WOULD VALUE ITS CUSTOMERS SAFETY AND MAKE A SAFETY RECALL ABOUT THIS ISSUE. *TR

AS I PULLED INTO A PARKING SPACE, THE ENGINE DIED AND FLAMES ABOUT 2' TALL SHOT OUT FROM BETWEEN THE HOOD AND COWL AND OUT OF THE INTERCOOLER INLET IN THE CENTER OF THE HOOD. THE FLAMES WERE FOLLOWED BY ABOUT 10 SECONDS OF A HUGE SMOKE CLOUD. IT TOOK ME ABOUT 90 SECONDS TO GET A FIRE EXTINGUISHER AND GET THE FIRE PUT OUT. I EXAMINED THE DAMAGE. THE PRESSURE SIDE POWER STEERING HOSE WAS RUBBING AGAINST THE SHEET METAL HEAT SHIELD OVER THE TURBOCHARGER. AFTER A WHILE, THE RELATIVE MOTION AND HEAT RUBBED A HOLE IN THE POWER STEERING HOSE. THE POWER STEERING HOSE THEN PUMPED POWER STEERING FLUID ALL OVER THE TURBOCHARGER, EXHAUST MANIFOLD, HEAT SHIELDS, HOOD, FIREWALL, ETC. WHEN THE POWER STEERING FLUID HIT THE HEAT SHIELDS AND EXHAUST, IT STARTED BURNING AND THIS CAUSED THE FIRE. I HAVE NOT FINISHED REPAIRING THE VEHICLE YET SO I DON'T KNOW THE COMPLETE EXTENT OF THE DAMAGE. AT THIS POINT, AT LEAST THE POWER STEERING HOSE AND FLUID NEED TO BE CHANGED. THE PRESSURE SIDE POWER STEERING HOSE HAS NO BRACKETS TO HOLD IT IN POSITION WITHIN ABOUT 1' OF THE TURBOCHARGER HEAT SHIELD. THE OUTSIDE OF THE HOSE IS RUBBER. THERE IS NO HEAT SHIELD OVER IT. IT IS GUARANTEED TO RUB AGAINST THE HEAT SHIELD AND FAIL THIS WAY. THE POWER STEERING RETURN HOSE ALSO HAS NO BRACKETS WITHIN 1' OF THE TURBOCHARGER HEAT SHIELD, BUT IT DOES AT LEAST HAVE A CORRUGATED ALUMINUM HEAT SHIELD OVER IT. *TR

Status: closed (inferred from source dates) · Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings
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.
