2011 Subaru Outback Fuel System Problems

P0420 CODE O2 SENSORS. I HAD THIS PROBLEM BACK IN 2017. CRUISE, SKID CONTROL, BRAKE LIGHT AND CHECK ENGINE LIGHT COME ON. SUBARU SAID IT WAS THE CATALYTIC CONVERTER, 02 SENSORS AND ASSOCIATED PIPING. SUBARU REPLACED IT FOR FREE IN 2017. NOT EVEN 2 YEARS LATER 8/2019, I AM DEALING WITH THE SAME ISSUE AGAIN. SAME DIAGNOSES. I HAVE SEEN A MULTITUDE OF COMPLAINTS ABOUT THIS ISSUE. SAW A REPORT OF A RECALL FOR THE FRONT 02 SENSOR ON REPAIRPAL BUT IT IS NOT LISTED ON SUBARU'S WEBSITE. SUBARU WANTS TO CHARGE 1900 TO FIX AND MAKE ME PAY 500.00 FOR A REPAIR THAT'S SHOULD NOT NEED TO HAPPEN IN LESS THAN TWO YEARS TIME!

THE TORGUE CONVERTER IS CAUSING NOISE, SHUTTERING, AND LATE DOWN SHIFTING REPLACEMENT OF A FAILING TORQUE CONVERTER HAS BEEN RECOMMENDED.

WHEN COMING TO A STOP, THE CAR STALLS SHUDDERS AND QUITS, THIS HAPPENS MORE OFTEN WHEN BRAKING HARDER THAN STANDARD. THE CAR CAN BE WARM OR COLD IT CAN BE REPLICATED ON COMMAND MOST OFTEN GOING UPHILL BUT WILL ALSO DO SAME ON LEVEL GROUND. DEALER REFERENCED POSSIBLY BAFFLE IN GAS TANK HAS DETACHED ALLOWING GAS TO SLOSH AWAY FROM PICK UP AREA IN TANK. SUGGESTED 200.00 TO DROP TANK INVESTIGATE AND 4-500 TO REPLACE TANK. ALSO REPORTED IN COMPLAINT 10966670 UNDER DRIVE TRAIN. TRIED LIQUID HEET FUEL ADDITIVE TO REMOVE POSSIBILITY OF WATER POOLING IN TANK. THE STALL HAPPENS MOST ON CITY STREET WITH DAUGHTER OR WIFE DRIVING.

WHEN I TURNED THE CAR IN THE AFTERNOON THE CRUISE CONTROL WAS FLASHING, CHECK ENGINE LIGHT ON AND E-BRAKE ON. I LOOKED ONLINE SUBARU FORUMS AND THEIR IS A LOT OF CHATTER FOR THE GAS CAP HAVING ISSUES. I CHECKED MY GAS CAP AND NOTICED THE RUBBER GASKET WAS BROKEN. I PURCHASED A NEW ONE FROM THE DEALERSHIP, DROVE THE CAR AND THE LIGHTS ARE NOW OFF AND WORKING NORMAL..WE'LL SEE WHEN I TAKE A 6HR TRIP IN A FEW DAYS.. *TR

I BACKED OUT OF A PARKING SPOT, STOPPED AND, WITH MY FOOT ON THE BRAKE, SHIFTED TO DRIVE TO PULL FORWARD. THE CAR SURGED FORWARD RAPIDLY. I STOOD ON THE BRAKES, THE SURGE CONTINUED VERY BRIEFLY AND THEN THE CAR FINALLY STOPPED. THIS WAS THE FIRST INCIDENT OF THIS KIND IN THE THREE YEARS I HAVE OWNED THE CAR. *TR

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

DURING THE 2 YEARS SINCE I PURCHASED MY 2011 OUTBACK 2.5I (CVT), THERE HAVE BEEN ABOUT 15 OCCASIONS WHERE I WAS GOING DOWNHILL, USING ENGINE BRAKING, WITH MY FOOT OFF THE ACCELERATOR, CRUISE CONTROL NOT ENGAGED, BUT GAS WAS FED TO THE ENGINE, RESULTING IN SPEEDS OF 45 TO 50 MPH (4500 RPM) IN 2ND GEAR. ONE INDICATOR THAT GAS IS BEING FED TO THE ENGINE IS THE FUEL ECONOMY GAUGE SHOWS POOR GAS MILEAGE. THIS DEFINITELY DOES NOT FEEL LIKE ENGINE BRAKING WHEN THE ENGINE IS SCREAMING AS YOU ARE SPEEDING DOWNHILL. USUALLY WHEN I DRIVE THE SAME STRETCH OF ROAD USING ENGINE BRAKING MY SPEED IS 30 TO 35 MPH IN 2ND GEAR AND THE FUEL ECONOMY GAUGE SHOWS NO FUEL IS BEING CONSUMED. SUBARU REFUSES TO COMMENT ON THIS PROBLEM SINCE I CANNOT REPRODUCE IT FOR THEM. I ASKED THE SERVICE MANAGER ABOUT THE SIMILAR BUT LESS SEVERE, REPEATABLE BEHAVIOR, OF CYCLING BETWEEN ACCELERATING TO OVER 2000 RPM AND DECELERATING TO ABOUT 1200 RPM. HE SAID THIS IS DONE TO MEET EMISSION STANDARDS. *TR

WHILE PULLING INTO A PARKING SPACE, THERE WAS SUDDEN ACCELERATION AS IF THE CHOKE HAD TURN ON, SIMILAR TO WHEN STARTING THE VEHICLE. IT LASTED ONLY A SHORT WHILE, BUT I DID HAVE TO PUT THE VEHICLE IN NEUTRAL. THIS ALSO OCCURRED ONCE BEFORE APPROX. ONE MONTH PRIOR THIS , WHILE PULLING INTO MY GARAGE. AM CURIOUS IF ANY OTHER REPORTS OF THIS TYPE HAVE BEEN REPORTED. *TR

FUEL GAUGE FAILS TO SHOW CORRECT AMOUNT OF FUEL IN THE TANK. FUEL GAUGE WILL ONLY SHOW ABOUT 2/3 FULL WHEN THE FUEL TANK IS FULLY FUELED. THERE ARE SEVERAL REPORTS OF SAME PROBLEM POSTED AT WWW.SUBARUOUTBACK.ORG/FORUMS REGARDING FUEL GAUGE INCORRECTLY DISPLAYING THE FUEL LEVEL. 2011 SUBARU OUTBACK 3.6 LIMITED, PURCHASED MAY 2010, 1ST OWNER. *TR
