2001 Subaru Forester Fuel System Problems

WHEN THE TEMPERATURE GETS COLD AND I TURN ON THE DEFROST TO WARM UP THE CAR WHILE PARKED I CAN SMELL GAS IN THE VEHICLE. IT GOES AWAY ONCE I START DRIVING. THIS IS A PROBLEM MANY SUBARU OWNERS HAVE BECAUSE A HOSE LOOSENS AND ALLOWS GAS TO LEAK OUT. ONCE THE CAR WARMS UP THE HOSE TIGHTENS AND THE PROBLEM GOES AWAY. THIS CAN POTENTIALLY CAUSE MY CAR TO CATCH ON FIRE.

WHEN IT IS BELOW 25 DEGREES FAHRENHEIT, FUEL LINES AND RELATED COMPONENTS (INCLUDING RETAINING CLIPS AND FITTINGS) LEAK GASOLINE, CAUSING GAS FUMES TO ENTER THE PASSENGER COMPARTMENT. THIS PROBLEM IS SOMETIMES REFERRED TO AS A FUEL LINE SEEP. FUMES THEN ENTER THE PASSENGER COMPARTMENT VIA THE HEATING VENTILATION SYSTEM OR THROUGH GENERAL AMBIENT ENTRY. EVEN WHEN THE HEAT IN THE PASSENGER COMPARTMENT IS OFF, FUMES ENTER THE COMPARTMENT. THIS EXPOSES PASSENGERS TO HARMFUL CARBON MONOXIDE AND HYDROCARBONS AS WELL AS POSING A FIRE RISK. THIS HAPPENS AT ALL SPEEDS FROM STAND-STILL TO 75 MPH. IN MODERATE COLD (25-15 DEGREES FAHRENHEIT), THE LEAKING STOPS AFTER THE ENGINE HAS WARMED. IN COLDER TEMPERATURES, THE LEAKING CONTINUES NO MATTER HOW LONG I DRIVE THE CAR. THE PROBLEM CAN BE TEMPORARILY SOLVED BY TIGHTENING THE HOSE CLAMPS ON THE FUEL LINES, BUT WHEN THE TEMPERATURE DROPS AGAIN, THE HOSE CLAMPS MUST AGAIN BE TIGHTENED. SOME OF THE CLAMPS ARE UNDERNEATH ENGINE COMPONENTS THAT ARE DIFFICULT TO REMOVE, SO THE PROCESS IS VERY TIME INTENSIVE AND DOES NOT ALWAYS STOP THE FUMES. THIS IS A COMMONLY DISCUSSED TOPIC IN AUTOMOTIVE DISCUSSION BOARDS ONLINE. THEREFORE, I BELIEVE IT IS WIDESPREAD. HERE ARE SEVERAL EXAMPLES: HTTP://WWW.SUBARUFORESTER.ORG/VBULLETIN/F88/GASOLINE-ODOR-INSIDE-CABIN-45495/ HTTP://WWW.SUBARUFORESTER.ORG/VBULLETIN/F87/SMELL-GAS-COLD-STARTS-41319/ HTTP://COMMUNITY.CARTALK.COM/DISCUSSION/1986611/COLD-WEATHER-GAS-SMELL-2003-SUBARU-FORESTER. *TR

IN COLD WEATHER WE GET A STRONG FUEL SMELL. THE SMELL ENTERS THE CAR AND GIVES EVERYONE A HEADACHE. OTHER SUBARU OWNERS WE KNOW HAVE THE SAME PROBLEM. SUBARU KNOWS OF THIS PROBLEM BUT WILL NOT MAKE A RECALL. ESTIMATES FOR A FIX RUN ABOUT $300. *TR

SUBARU FORESTER SMELLS OF GAS INSIDE CAB WHEN WEATHER IS COLD. GAS LEAK VISIBLE FIRST TIME IT OCCURRED IN 2013. I TIGHTENED A CLAMP AND LEAK STOPPED. THIS WINTER I CANNOT SEE THE LEAK, BUT THE FUEL SMELL OVERTAKES MY CAR ABOUT 5 MINUTES INTO WARMING UP. EVENTUALLY IT DISSIPATES BUT I DO BELIEVE THAT THERE IS A LEAK SOMEWHERE IN THE VEHICLE. THIS SEEMS TO BE EPIDEMIC IN SUBARUS. *TR

BOTH MY HUSBAND AND I HAVE EXPERIENCED HEADACHES AND NAUSEA FROM THE FUMES SINCE WINTER 2012 WHEN OUR FORESTER FIRST STARTED LEAKING. THIS HAPPENS AT ALL SPEEDS FROM STAND-STILL TO 75 MPH. IN MODERATE COLD (25-15 DEGREES FAHRENHEIT), THE LEAKING STOPS AFTER THE ENGINE HAS WARMED. IN COLDER TEMPERATURES, THE LEAKING CONTINUES NO MATTER HOW LONG I DRIVE THE CAR.

WHENEVER THE OUTSIDE TEMPERATURE DROPS BELOW 20 DEGREES FAHRENHEIT, THERE IS A STRONG ODOR OF GASOLINE IN AND AROUND THE CAR. WHEN TAKEN TO A MECHANIC, I WAS INFORMED THAT ALL OF THE HOSE CLAMPS ON THE FUEL LINES WERE LOOSE. THEY WERE THEN TIGHTENED BUT EVERY TIME THE OUTSIDE TEMPERATURE DROPS, IT HAPPENS AGAIN. IT HAPPENS WHETHER PARKED OUTSIDE OR IN A GARAGE.

THE ISSUE IS IN REGARD TO MY 2001 SUBARU FORESTER, WHEN THE WEATHER COOLS OFF TO BELLOW 0, A STRONG SMELL OF GASOLINE DEVELOPS INSIDE THE PASSENGER CABIN. I HAVE SMALL KIDS AND ASIDE FROM A POSSIBILITY OF AND ENGINE FIRE AM ALSO WORRIED ABOUT IMPACT OF BREATHING THE STRONG GASOLINE FUMES IN THE CABIN. FROM OTHER SUBARU OWNERS FEEDBACK (SEE BELLOW FROM SUBARU BLOG), THIS APPEARS TO BE WIDESPREAD ON THE FORESTER MODELS UP TO 2003 AND EVEN IN OTHER SUBARU MODELS, THE SUBARU DEALER AND OTHER MECHANICS HAVE INDICATED THE POSSIBILITY OF FUEL HOSE SHRINKAGE DURING COLD WEATHER AS THE CAUSE FOR SOME FUEL LEAKS IN THE ENGINE COMPARTMENT AND REPLACEMENT CAN BE EXPENSIVE WITHOUT GUARANTEEING IT WILL CORRECT THE CONDITION. WHATEVER THE REASON MAY BE, THIS IS NOT AN ISOLATED CASE WHICH I THINK WARRANTS A FULL INVESTIGATION TO DETERMINE THE DEFECT AND FIND A CORRECTION TO BE PAID BY SUBARU. I COUNT ON YOU FOR SOME HELP ON THIS. THANK YOU. *TR

THERE ARE TWO ORGANIC TUBES THAT CARRY FUEL, ABOVE THE ENGINE. IN COLD WEATHER, THEY LEAK WHERE CLAMPED TO METAL TUBES AND FITTINGS. THE FUEL LEAKS ONTO THE ENGINE. THE INDICATION IS A SMELL OF GASOLINE IN THE PASSENGER COMPARTMENT. *TR

2001 SUBARU FORESTER REPEATEDLY DECELERATES AND/OR SPONTANEOUSLY ACCELERATES AT ALL SPEEDS, TRAFFIC CONDITIONS, WEATHER CONDITIONS. POTENTIAL FOR CATASTROPHE. ALREADY SOME NEAR MISSES.*AK
