HE STATED THAT IT WAS LUCK THAT THE VEHICLE IN-FRONT TURNED LEFT; AND HE WAS ABLE TO AVOID A CRASH. THE MANUFACTURER WAS CONTACTED AND STATED THAT THEY WOULD NOT ASSIST WITH THE REPAIR, BECAUSE THE ABS FAILURE WARRANTY EXPIRED AT 36,000 MILES. THE FAILURE MILEAGE WAS 119,000 AND THE CURRENT MILEAGE WAS 120,000. UPDATED 02/09/11*LJ UPDATED 02/28/11

SEVERAL TIMES (ABOUT ONCE A YEAR ON AVERAGE) SINCE I PURCHASED MY SUBARU WRX IN 2001 THE BRAKES BRIEFLY FAIL. THE DESCRIPTION SEEMS IDENTICAL TO THAT OF THE 2010 PRIUS IN THAT THERE IS NO BRAKING FOR A BRIEF TIME WHEN GOING OVER BUMPS, RAILROAD TRACKS OR SIMPLY GOING DOWNHILL ON A WET ROAD. THE MOST RECENT INCIDENT I WOULD GUESS HAPPENED IN THE FALL OF 2009 WHEN GOING DOWN A HILL WITH SUDDEN BRAKING REQUIRED ON A WET SURFACE. WITHIN THE FIRST YEAR OF OWNERSHIP I ALERTED OUR SUBARU DEALER OF THE PROBLEM AND THEY DID "A FIRMWARE UPDATE". I DON'T THINK THIS MADE A DIFFERENCE BUT SINCE IT IS A RARE BUT SCARY OCCURRENCE I REALLY COULD NOT TELL. *TR

DRIVING DURING VERY LIGHT RAIN IN LEFT LANE ABOUT 30 MPH, CAR IN FRONT (ABOUT 2-3 CAR-LENGTHS AHEAD) STARTS BRAKING. I PRESSED THE BRAKES AND ABS CAME ON WITHOUT ANY REASON, THE CAR DID NOT SLOW DOWN ALMOST AT ALL, FORCING ME TO SWITCH THE LANE QUICKLY TO THE RIGHT. WHILE SWITCHING LANES, CAR STARTED SKIDDING AND DIVING THE NOSE TO THE RIGHT/TAIL TO THE LEFT, I TRIED TO CORRECT THE NOSE TO THE LEFT, BUT THAT CAUSED A MORE DANGEROUS SKID TO THE LEFT, TOWARD ONCOMING TRAFFIC. I TURNED THE WHEEL RIGHT AGAIN, TRYING TO REGAIN CONTROL, BUT THE CAR SPUN OUT AND HIT A TREE ON RIGHT SIDE OF ROAD WITH THE DRIVER'S DOOR. I WAS TAKEN TO A HOSPITAL AND STAYED THERE OVERNIGHT FOR OBSERVATION, RELEASED NEXT DAY. NOBODY WAS INJURED, THE TREE HAD A FEW VERY SMALL SCRATCHES. I AM STILL WAITING TO FIND OUT IF THE CAR WILL BE REPAIRABLE OR TOTALED. *NM

LIGHT AHEAD TURNS RED - I APPLY THE BRAKES AS USUAL, BUT THE PEDDLE SUDDENLY SINKS ABOUT AN INCH AND I FEEL ABS COME ON. IT FEELS AS IF THE BRAKES HAVE NO STOPPING POWER AND ARE ONLY WORKING AT ABOUT 10%. I LET UP ON THE BRAKES AND TRIED AGAIN, AND WAS ABLE TO STOP BEFORE HITTING THE CAR IN FRONT OF ME. THIS HAS ALSO HAPPENED ONCE BEFORE, ON SOME METAL DRAWBRIDGE GRATING. IT SEEMS AS IF THE ABS COMES ON IN TIMES WHEN IT SHOULD NOT, WHICH CAUSES THE BRAKES TO PRACTICALLY NOT WORK. IF A CAR HAD BEEN CLOSER IN FRONT OF ME, I WOULD HAVE HIT IT. *AK

TODAY I SENT THE FOLLOWING EMAIL TO SUBARU OF AMERICA CONCERNING THE INVESTIGATION OF ABS DEFECT IN WRX VEHICLES. I HAVE EXPERIENCED THE PROBLEM ON NUMEROUS OCCASIONS, AND ON NO OCCASION WAS I DRIVING IN AN "AGGRESSIVE" MANNER OR "HARD' BRAKING. NOR WAS MY PREVIOUS COMPLAINT TO NHTSA A "PARROTING" OF SOMEONE ELSE'S PROBLEM FROM THE IMPREZA WEBSITE, AS SUBARU HAS ACCUSED. THE ABS IS OVERLY SENSITIVE TO BUMPY SURFACES AND IS A SAFETY RISK, PERIOD. MY EMAIL TO SUBARU OF AMERICA: I HAVE JUST REVIEWED SOA'S LETTER DATED 9/10/04 TO NHTSA RE YOUR INVESTIGATION OF ALLEGED ABS PROBLEMS IN WRX'S. I AM DISMAYED BY SOA'S INABILITY TO DOCUMENT, AND REFUSAL TO ACKNOWLEDGE, THE ABS PROBLEM. I AM INSULTED THAT SUBARU BLAMES THE PROBLEM ON "AGGRESSIVE DRIVING PATTERNS." THE PROBLEM REGULARLY OCCURS AT ONE POINT IN MY DAILY URBAN COMMUTE WHEN I BRAKE FOR A TRAFFIC LIGHT OVER A BUMPY SURFACE. I AM USING ONLY 15% OF THE BRAKING CAPABILITY AT 20 MPH WHEN THE ABS FAULT OCCURS-- HARDLY "AGGRESSIVE" OR "HARD" BRAKING, AND HARDLY A SITUATION THAT ONLY AGGRESSIVE PERFORMANCE DRIVERS WOULD ENCOUNTER. WHEN IT OCCURS, THERE IS A SUDDEN, DRAMATIC REDUCTION IN DECELERATION WHICHIS NO LONGER PROPORTIONAL TO PEDAL PRESSURE, AND INCREASED PRESSURE IS INEFFECTIVE WHILE THE ABS IS "CONFUSED" BY THE BUMPY SURFACE. SEVERAL TIMES I HAVE HAD SCARY MOMENTS WHEN THE DROP IN DECELERATION HAS RESULTED IN NEARLY REAR-ENDING THE VEHICLE IN FRONT OF ME. I AM VERY PUZZLED WHY AN EVENT, THAT FOR ME IS SO PREDICTABLE AND REPEATABLE, HAS ESCAPED YOUR ANALYSIS. *AK I FURTHER TAKE OFFENSE TO THE CLAIM IN YOUR LETTER THAT MANY OF THE COMPLAINTS TO THE NHTSA WERE DISHONEST REPETITIONS OF PROBLEMS A FEW HAD DESCRIBED ON AN OWNERS WEBSITE. NICE TRY, BUT I CAN ATTEST TO THE VALIDITY OF THE PROBLEM IN MY CAR, HAVING EXPERIENCED IT DOZENS OF TIMES. DISCUSSION ON THE WEBSITE HAS INFORMED OWNERS OF THE PROBLEM AND MAY HAVE PREVENTED SOME ACCIDENTS, SOMETHING I CANNOT SAY FOR SUBARU! CHARLES F. VISSER. *AK

THIS COMPLAINT IS IN REGARDS TO A CONTINUING PROBLEM WITH MY 2002 SUBARU IMPREZA WRX WAGON. WHILE BRAKING ON UNEVEN ROADS, ESPECIALLY WHEN ENCOUNTERING POTHOLES OR OTHER CONDITIONS WHERE ONE OR MORE TIRES MOMENTARILY LOSE TRACTION, THE ABS WILL ENGAGE AND REMAIN ENGAGED FOR A SIGNIFICANT AMOUNT OF TIME (AFTER THE MOMENTARY OR INSTANTANEOUS LOSS OF TRACTION). THIS CAUSES THE CAR TO BRAKE INEFFECTIVELY OR SOMETIMES NOT AT ALL. THIS HAS PUT ME IN UNCOMFORTABLE AND/OR DANGEROUS SITUATIONS ON NUMEROUS OCCASIONS WHEN THE CAR DOES NOT BRAKE AS EXPECTED. IT IS MY UNDERSTANDING THAT THIS ISSUE IS CURRENTLY UNDER INVESTIGATION BY THE NHTSA AND SUBARU, SO I AM AWAITING THE OUTCOME OF THIS INVESTIGATION.

I WAS RECENTLY RIDING WITH WHAT SUBURBAN SUBARU IN VERNON/MANCHESTER, CT SAY WAS 50% LIFE LEFT ON MY BREAK PADS IN MY 2002 WRX SEDAN. WHEN STOPPING FOR A FAST YELLOW TO RED LIGHT CHANGE FROM ABOUT 50 MILES AN HOUR THEIR WAS NO RESPONSE ON THE BREAK PEDAL. I QUICKLY TOOK MY FOOT OFF AND PRESSED AGAIN, EVEN HARDER THIS TIME, WHICH ENGAGED THE ABS AND LEFT ME COMING TO A BANGING ABS STOP IN THE MIDDLE OF THE INTERSECTION OF ROUTE 5. LUCKILY ALL THE CARS AT THE INTERSECTION NOTICED WHAT HAD HAPPENED AND THERE WAS NO ACCIDENT. I JUST WANT TO MAKE SURE THIS PROBLEM WITH THE BRAKES NOT RESPONDING AT ALL GETS RECOGNIZED AND LOOKED INTO FURTHER. HOWEVER, I CAN PLAINLY SAY THAT AFTER THAT INCIDENT, I DO NOT TRUST THE BREAKS ON MY 02 WRX. I PLAN ON KEEPING THIS CAR, BUT I DEMAND RELIABLE BRAKING LIKE ALL OTHER DRIVERS. *AK

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.
