ON MY 2002 SUBARU IMPREZA WRX SEDAN WHENEVER I GO OVER A BUMP OR IMPERFECTION IN THE ROAD (NO MATTER HOW BIG OR SMALL) THE ABS KICKS IN AND IF I HIT THE BRAKES DIRECTLY AFTERWARDS THE PEDAL GOES TO THE FLOOR AND I HAVE SEVERELY WEAK BREAKS FOR 2-3 SECONDS THEN THEY COME BACK. IVE REPLACED THE BRAKE ROTORS, PADS, AND BRAKE FLUID AND THE ISSUE STILL HAPPENS. SUBARU OF AMERICA CLAIMS IT IS NOT A PROBLEM BUT HAVE NEVER HAD THIS ISSUE WITH ANY OTHER CAR WITH ABS. IM VERY FAMILIAR WITH ABS AND KNOW HOW IT WORKS THE PROBLEM IS AFTER IT ENGAGES IF YOU BRAKE AGAIN 2-3 SECONDS AFTER IT ENGAGED THE PEDAL GOES TO THE FLOOR AS IF THERES ONLY 20% BRAKEING FORCE. IVE ALMOST BEEN IN SEVERAL ACCIDENTS DUE TO THIS ONE TIME I WAS PULLING INTO A PARKING SPOT GOING 5MPH AND THIS HAPPENED AND I ALMOST DRIFTED INTO A PARKED CAR. PLEASE LOOK INTO THIS. PLEASE VIEW THIS WEBSITE HTTP://FORUMS.NASIOC.COM/FORUMS/SHOWTHREAD.PHP?T=102893 MANY 2002 AND UP SUBARU OWNERS ARE EXPERIENCEING THIS. THE ABS ISNT THE PROBLEM AGAIN ITS THE LOSS OF BRAKEING AFTER THE ABS WAS ENGAGED MAYBE THE ABS COMPUTER ISNT WORKING CORRECTLY/FAST ENOUGH? THANK YOU

IF I TRY TO BRAKE OVER ROUGH OR SLIPPERY PAVEMENT IN MY 2002 SUBARU IMPREZA WRX, THE ABS SYSTEM SHUTS OFF THE BRAKES. POTHOLES, MANHOLE COVERS, FROST HEAVES, ICY PATCHES, ANY OF THESE CAUSE THIS BEHAVIOR.

IF I TRY TO BRAKE OVER ROUGH OR SLIPPERY PAVEMENT IN MY 2002 SUBARU IMPREZA WRX, THE ABS SYSTEM SHUTS OFF THE BRAKES. POTHOLES, MANHOLE COVERS, FROST HEAVES, ICY PATCHES, ANY OF THESE CAUSE THIS BEHAVIOR. ALSO, IN NOVEMBER 2004, WHILE DRIVING DOWNHILL AT ABOUT 30 TO 35 MPH ON DRY AND MOSTLY CLEAN PAVEMENT, A TRUCK DRIVING IN FRONT OF ME BRAKED GRADUALLY. I HIT MY BRAKES TO MAINTAIN A DISTANCE, BUT IT WAS A SECTION OF RIPPLED PAVEMENT AND THE ABS SYSTEM SHUT OFF THE BRAKES SO COMPLETELY FOR ABOUT 10 SECONDS. MY CAR WAS ACTUALLY PICKING UP SPEED DUE TO THE DOWNHILL. I AM SURE THAN IN ANY OTHER CAR I'VE HAD, I WOULDN'T HAVE HAD ANY TROUBLE SLOWING DOWN. I AVOIDED REAR-ENDING THE TRUCK BY SLOWING THE CAR WITH AGGRESSIVE ENGINE BRAKING. I ALSO STEERED TOWARDS THE OTHER SIDE OF THE ROAD, WHERE THERE WAS NO TRAFFIC AT THAT MOMENT AND THE PAVEMENT WAS CLEANER, SO I COULD SLOW DOWN. ANOTHER TIME I REAR-ENDED A VEHICLE THAT STOPPED IN FRONT OF A POTHOLE, ALTHOUGH DAMAGE WAS MINOR. I'VE ALSO HAD A LARGE NUMBER OF SCARY NEAR - MISSES WITH REAR-ENDING OTHER VEHICLES, AND ON A FEW OCCASIONS SLID OUT INTO INTERSECTIONS WITH FROST HEAVES LEADING UP TO A STOP SIGN OR STOP LIGHT, BECAUSE MY BRAKING SPACE ESTIMATE WAS FAR LESS THAN I ACTUALLY NEEDED. I RECENTLY REPLACED ALL BRAKE PADS AND DISCS. THE REAR PADS FIT IN THE CALIPERS SO TIGHTLY I HAD TO POUND THEM OUT WITH A HAMMER AND PUNCH. BOTH PADS AND ROTORS WERE WORN VERY UNEVENLY. REPLACEMENT REAR PADS FIT IN THE SAME WAY. THEN I REALIZED SOMETHING WAS WRONG WITH THE FIT, SO I GROUND DOWN THE TABS TO GET A GOOD SNUG FIT RATHER THAN AN INTERFERENCE FIT AND JAMMING, SO THEY SLIPPED INTO PLACE NORMALLY. AFTER MAKING THIS CHANGE TO MY BRAKES, THEY WORK VERY WELL. I NEARLY SOLD THE CAR DUE TO THIS ISSUE, BUT INSTEAD DROVE IT FOR A WHILE WITH THE ABS SYSTEM DISABLED. MY LOCAL SUBARU DEALER TOLD ME THIS IS HOW ABS SYSTEMS ARE SUPPOSED TO WORK, EVEN THOUGH THERE IS CLEARLY A BIG PROBLEM.

ANTILOCK BRAKING SYSTEM ENGAGES ON DRY PAVEMENT WHEN IT ENCOUNTERS BUMPS, PEDAL GOES ALMOST TO THE FLOOR AND BRAKING FORCE IS SEVERELY REDUCED. I HAVE DRIVEN MANY CARS WITH ABS AND NOTHING LIKE THIS HAS EVER HAPPENED TO ME. I HAVE SORT OF LEARNED TO "DRIVE AROUND" THE PROBLEM, BUT ON A COUPLE OF OCCASIONS WHERE EMERGENCY BRAKING WAS CALLED FOR IT HAS NEARLY CAUSED ME TO GET INTO AN ACCIDENT - ONCE FORCING ME TO DRIVE UP ONTO AND OVER A CURB AND INTO A DITCH. DESTROYING ONE OF MY WHEELS IN THE PROCESS. SOMEONE RAN A RED LIGHT AND I COULDNT STOP FROM 30 MPH IN WHAT WOULD HAVE BEEN PLENTY OF ROOM WITH A NORMAL BRAKING SYSTEM. PROBLEM HAS BEEN THERE SINCE CAR WAS NEW, WHEN I INQUIRED ABOUT IT WITH MY DEALER I WAS INFORMED THAT "ALL WRXS DO THAT, ITS NORMAL" BUT AFTER TALKING WITH SEVERAL OTHER OWNERS OF THE SAME CAR I CAN TELL YOU THAT ALTHOUGH WE ALL MIGHT EXPERIENCE IT, ITS NOT NORMAL AT ALL AND QUITE SCARY. AS AN EXPERIMENT I FOUND A PARKING LOT WITH SOME BUMPS ON IT THAT WOULD CAUSE THE ABS TO GO NUTTY, I THEN PULLED THE ABS FUSE AND WENT OVER THE SAME PART OF THE PARKING LOT AT THE SAME SPEED AND I COULD GET TONS MORE BRAKING FORCE WITHOUT LOCKING UP THE WHEELS THAN I COULD WITH THE ABS ON, SOMETHING IS DEFINITELY SCREWY HERE. *AK

MY MODEL YEAR 2002 SUBARU IMPREZA WRX WAGON HAS HAD A SLIGHT REOCCURING PROBLEM WITH WHAT SEEMS TO BE A FAULTY ABS BRAKING SENSOR. *AK THE CAR SUFFERS FROM A DROP IN PRESSURE OF BRAKE PEDAL FEEL AND BRAKE PERFORMANCE OVER UNEVEN OR BUMPY ROADS. WHEN BRAKING UNDER NORMAL DRIVING CONDITIONS IF A BUMPY OR UNEVEN SURFACE IS ENCOUNTERED WHILE BRAKING THE ABS KICKS IN AND THERE IS A LOSS IN CONTROL VIA THE BRAKE PEDAL OF THE BRAKING FORCE. THIS CONDITION HAPPENS EVERY TIME THE CONDITIONS ARE PRESENT AS DESCRIBED, AND CAN BE QUITE DISCONCERTING. IT IS OBVIOUS THAT UNDER PANIC SITUATIONS, COUPLED WITH LESS THAN IDEAL ROAD SURFACES, THIS CONDITION COULD PROVE VERY DANGEROUS, AS THE BRAKING DISTANCE OF THE CAR INCREASES DRAMATICALLY DURING THIS ACTION.

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.

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.
