GASOLINE FUEL SMELL IN CABIN OF CAR, WHEN DRIVING AND WARMING IT UP IN THE MORNING. HAD JUST HAD CAR SERVICED BY DEALERSHIP FOR 60,000 MILE CHECK UP. WAS AFRAID TO DRIVE CAR SINCE I COULD SEE GASOLINE POOLED ON ENGINE BLOCK AND WAS SMOKING AS IT EVAPORATED. TOOK TO DEALERSHIP WHERE I PURCHASED VEHICLE TO HAVE IT SERVICED. WAS INFORMED OF A SERVICE BULLETIN SUBARU PUBLISHED 4/1/03 - BULLETIN NO. 09-36-03 CONCERNING THE PROBLEM AND REPAIR. ASKED DEALERSHIP IF PROBLEM WAS COVERED UNDER EXTENDED WARRANTY. THEY SAID NO. SINCE THIS PROBLEM WAS IDENTIFIED BY THE MANUFACTURER OF THE VEHICLE BEFORE MY PURCHASE OF THE CAR AND IS IN FACT A SAFETY ISSUE, I AM CONFUSED AS TO WHY THIS REPAIR IS NOT COVERED BY THE DEALERSHIP/MANUFACTURER OF THE VEHICLE. PAID FOR REPAIR COST OF $ 818. DEALERSHIP UNWILLING TO TRY TO HELP RESOLVE MY ISSUE WITH THE REPAIR. CONTACTED AUTO MANUFACTURER DIRECTLY AND AM WAITING FOR RESPONSE. *JB

SINCE THE WEATHER HAS GOTTEN COLDER THERE IS A STRONG SMELL OF GASOLINE COMING FROM THE ENGINE COMPARTMENT. THIS IS DUE TO A LEAK IN THE FUEL LINE BETWEEN A RUBBER HOSE AND A METAL FUEL LINE. SUBARU IS AWARE OF THE PROBLEM BUT HAS NOT ISSUED A RECALL. (TSB 09-36-03) SEE POST HERE: HTTP://FORUMS.NASIOC.COM/FORUMS/SHOWTHREAD.PH…

RAW FUEL SMELL DURING COLDER WEATHER. THE SMELL IS FROM THE ENGINE COMPARTMENT AND IS DUE TO POORLY DESIGNED FUEL DELIVERY PIPING/HOSES. RAW FUEL IS LEAKING FROM THE FUEL DELIVERY PIPING/HOSES AND THEN PUDDLES ON THE ENGINE BLOCK. THIS IS A KNOWN DEFECT AND SUBARU OF AMERICA STILL WILL NOT ACKNOWLEDGE ANY ISSUES NOR FIX THE PROBLEM. THE THREAT OF ENGINE FIRE IS VERY REAL AS IS PERSONAL INJURY AND/OR DEATH. I STRONGLY ENCOURAGE NHTSA TO INVESTIGATE THIS PROBLEM BEFORE SOMEONE IS SERIOUSLY HURT OR KILLED. TO FIX THIS PROBLEM WOULD BE MUCH BETTER FOR SOA THAN TO DEAL WITH LAWSUITS INVOLVING INJURY & DEATH. *JB

THIS IS A FOLLOW UP TO COMPLAINT 10144181. I TRIED TO CALL IN A FOLLOW UP AND WAS TREATED WITH TOTAL INDIFFERENCE. THE WEATHER IS NOW IN THE -8 TO +5 RANGE HERE IN WESTERN NE AND THE FUEL LEAK DOES NOT STOP, EVER. AFTER DRIVING 20 MILES TO WORK AND PARKING THE SMELL IS SO STRONG I FELT LIGHT HEADED, HEADACHE AND NAUSEOUS. A CO-WORKER PARKED 2 SPACES AWAY COULD SMELL IT GETTING OUT OF HIS CAR. I HAVE PARKED THE CAR. I WILL NOT SUBJECT MYSELF OF MY FAMILY TO THE HEALTH AND FIRE RISK. I GUESS I WILL WAIT UNTIL SOMEONE DIES FROM A FIRE OR ASPHYXIATION AND THEN SEE IF THERE IS ANY RECALL OR REACTION FROM THE NHTSA. THIS IS CUT DIRECTLY FOR YOUR WEB SITE. HTTP://WWW.SAFERCAR.GOV/PAGES/ODIFAQSREV2.HTM#OD5 WHAT ARE EXAMPLES OF SAFETY DEFECTS? EXAMPLES INCLUDE: PROBLEMS WITH FUEL SYSTEM COMPONENTS, PARTICULARLY IN THEIR SUSCEPTIBILITY TO CRASH DAMAGE, THAT RESULT IN LEAKAGE OF FUEL AND POSSIBLY CAUSE VEHICLE FIRES. FORGET CRASH DAMAGE, THIS THING LEAKS FUEL SITTING STILL. REVIEWING THIS MODEL YEAR ON YOUR SITE I NOTICE PEOPLE ARE LOGGING COMPLAINTS UNDER THE IMPREZA MODEL AND THE WRX MODEL AND IF YOU LOOK THROUGH THE COMPLAINTS ON THESE SYMPTOMS THERE ARE HUNDREDS OF COMPLAINTS. I AM SHOCKED THAT NO RECALL HAS BEEN FORCES CONSIDERING IT IS, BY YOUR OWN DEFINITION, A SAFETY HAZARD. *JB

WITH REGARDS TO THE INVESTIGATION LISTED BELOW, I WOULD LIKE TO ATTEST THAT THIS PROBLEM HAS NOT BEEN ADDRESSED. AS REGARDS THE LEAKING OF FUEL INTO THE ENGINE COMPARTMENT, IT IS A MORE SERIOUS HAZARD THAN INDICATED IN YOUR IMPOVERISHED DATA. IN MANY CASES, THE FUEL DOES NOT CEASE TO LEAK WHEN THE CAR HAS WARMED UP, AND WILL CONTINUE TO LEAK FUEL STEADILY. THIS PRODUCES PUDDLES ON THE HOT INTAKE MANIFOLD, AND TOXIC CONDITIONS FOR PASSENGERS AND BYSTANDERS. AS MENTIONED IN SUBARU TSB 09-36-03, UNDER COLD WEATHER CONDITIONS, FUEL WILL LEAK FROM A RUBBER-METAL JOINT IN THE FUEL LINE. THE REASON GIVEN IS THAT THE STIFFENING OF THE RUBBER IN COLD WEATHER DEPRIVES THE MATERIAL OF THE RESILIENCY NEEDED TO PROVIDE STRAIN RELIEF FOR THE HIGH PRESSURE RUBBER-METAL JOINT, THIS STRESSING THE JOINT, AND ALLOWING FUEL TO LEAK FROM IT. IN MY CASE, AND IN THE CASE OF MANY OTHERS I HAVE RESEARCHED, THE FUEL WILL CONTINUE TO LEAK EVEN AFTER THE ENGINE IS WARMED UP, CONTRARY TO YOUR REPORT. I BELIEVE THAT YOUR REPORT HAS UNDERSTATED THE PROBLEM, AND BELIEVE THAT A RECALL SHOULD BE STRONGLY RECOMMENDED. == NHTSA ACTION NUMBER : PE04002 NHTSA RECALL CAMPAIGN NUMBER : N/A MAKE / MODELS : MODEL/BUILD YEARS: SUBARU / IMPREZA 2002-2003 SUBARU / WRX 2002-2003 MANUFACTURER : SUBARU OF AMERICA, INC.

EXTREMELY STRONG RAW FUEL SMELL INSIDE CAB OF CAR AND IN ENGINE COMPARTMENT. FOUND FUEL LEAKING FROM A LINE AND POOLING ON THE ENGINE BLOCK. HAVE READ NUMEROUS POSTS ABOUT THIS ON THE MULTIPLE SUBARU WRX AND RELATED WEB FORUMS. THE PROBLEM APPEARS TO BE COMING FROM A LOOSE CLAMP WHERE A RUBBER HOSE MEETS A METAL FUEL LINE....I CAN VISIBLY SEE FUEL DRIPPING ONTO THE ENGINE!. I CANNOT GET AT ALL THE HOSE CLAMPS AND CANNOT AFFORD THE $400 - $600 OTHERS ON THE FORUMS HAVE BEEN QUOTED FOR THE FIX. SUBARU HAS RELEASED A TSB FOR THIS PROBLEM ON 2002 WRX'S LIKE MINE BUT FOR SOME REASON HAS NOT ISSUES A RECALL. I GUESS IT'S GOING TO TAKE A BURNT UP FAMILY TO GET IT TAKEN CARE OF....I JUST HOPE IT'S NOT MINE. *JB

IT WAS INTERMITTENT AND I REPORTED IT AT LEAST 3 OR 4 TIMES AND THE DEALER COULDN'T REPRODUCE IT.. FINALLY AFTER DOING IN FOR OVER A YEAR IT HAS GOTTEN BAD ENOUGH THEY COULD REPRODUCE IT.. THEY TORE IT DOWN AND THE FIRST GEAR SYNCHO IS BAD AND THEY WILL NOT COVER IT UNDER WARRANTY STATING DRIVER ABUSE.. THIS IS TOTAL BS I NEVER ABUSED THE CAR, IT HAS BEEN DOING IT FOR A WHILE AND OTHER DRIVERS HAVE HAD THE SAME PROBLEM. IN FACT BETWEEN MY WIFE AND I WE HAVE HAD 6 CARS WITH STANDARDS AND HAVE NEVER HAD SUCH A PROBLEM.. THE ABUSE CLAIM IS JUST TO GET OUT OF PAYING FOR A FAILURE OVER TIME IN A FAULTY TRANSMISSION AND THE EXTENDED WARRANTY I HAVE IS SUPPOSED TO COVER IT.*JB

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.
