2010 Subaru Outback engine problems

ENGINE

This car is a very well-maintained, low-use vehicle with regular oil changes and routine maintenance performed on schedule. Early in this drive, I noticed an unusual hissing sound as I approached a stop. When I tried to brake, I realized my brakes didn't seem to be responding. I pressed the brake pedal harder and realized that with 50-100 pounds of pressure (guess), I could slow the car down. As I came to a stop, the engine died. I restarted the car, and it died again immediately. After the following restart, I realized I could manually keep the RPM up in neutral while at stops, and press with significant force to get the car to stop. Had I not been comfortable two foot driving or understood the issue, this surely would have resulted in a crash of some sort. The car indicated a check engine light, loss of traction control, a flashing BRAKE light, and a flashing cruise control light. I took the car immediately to a local shop where they identified the problem as a vacuum leak at the brake booster. The plastic piece that the hose clamps onto had cracked off, leading to this problem. This make and model does not seem to have a check valve downstream of this component.

I see many many complaints about the head gasket material Subaru used was not compatible with the very fluid that is needed for the cars engine to not blow up.....coolant. Subaru knows the head gasket material is ruined by the coolant it needs but has left us consumers to deal with a very costly, devastating issue such as what I just want through and am still in the middle of a fight with dealer who sold me a car for 10995 and I had it 2 weeks....coolant blew everywhere had to fight with dealership to get them to tow it. I was yelled at, hung up on, calls not returned all while I have no car no way to work and as a [XXX] and a child to raise, I do not have options and live by a thread and paycheck to paycheck.....It should not be allowed that Subaru doesn't fix that since it is a manufacturing defect that they made it incompatible with the coolant it needs.

ENGINE

Vehicle has an automatic transmission and it stalls when stopping. There is no warning light on the dash. This happens more frequently when the vehicle is warm, in early operation it may only hesitate or run rough while stopping. A warm a stop is more likely to stall the vehicle than a slow stop. Hard braking at operating temperature will stall the vehicle without fail. This has been happening since I bought it and it occurs with each drive every day.

ENGINE

All instrument and waning lights illuminated and the engine shut down while driving. Took to the Subaru dealer repair shop and the vehicle was diagnosed with a head gasket leak that caused oil to mix with the coolant. This is a low mileage vehicle, 67,597 miles, that has been maintained by Subaru certified mechanics.

ENGINE

Total engine failure at just 75k miles. Barely driven, maintenance schedule always kept up to date, out of nowhere engine stopped and I was told the oil was completely empty. They were unable to resolve by adding oil. Also, transmission light has been on for 3+ years. Have been told by every repair shop who has checked this that it’s just a glitch in the electrical system and the transmission is fine. A few weeks prior to engine failure, the car began to have trouble accelerating and made a sort of “race car” sound. Barely could go past 40 mph without slamming on gas. Finally, doors have randomly decided to stop locking and unlocking while using key fob. Batteries have been replaced. Some doors work, some do not (namely, the driver side door). Other misc electrical issues like USB failure.

MY COOLING SYSTEM DOES NOT WORK CORRECTLY, WE HAVE CHANGED THE RADIATOR TWICE AND THE THERMOSTAT TWICE. I HAVE TAKEN IT TO SUBARU OF CHERRY HILL AND ALSO TO SUBARU OF JAX WHERE MY FATHER IN LAW IS A SENIOR MASTER TECH. MY CAR HAS EVERYONE BAFFLED. EVERYTHING IN MY COOLING SYSTEM BACKS UP INTO MY OVERFLOW AND THAN I LOSE ALL MY COOLANT. I SEE THERE WAS A RECALL IN 2010 FOR MY YEAR OUTBACK MANUFACTURED BETWEEN JULY 31 TO DEC 2009 AND MY CAR FALLS IN THOSE DATE RANGES BUT WAS NEVER INCLUDING IN THIS COOLING SYSTEM RECALL. I HAVE CONTACTED SUBARU OF AMERICA AND THEY SAID THERE IS NOTHING THEY CAN DO FOR ME. THE ISSUE ONLY HAPPENS WHEN DRIVING ON BOTH CITY STREETS AND HIGHWAYS. BC OF THE ISSUE MY CAR HAS JUST SHUT DOWN ON ME LUCKILY IT WAS WHEN I WAS PULLING INTO PARKING LOTS AND NOT HIGHWAYS.

MAJOR SAFETY ISSUE - VEHICLE HAS STARTED STALLING WHEN COMING TO A STOP OR STARTING TO TURN. THIS HAS ALMOST CAUSED SEVERAL ACCIDENTS TURNING OUT ONTO THE HIGHWAY. SUBARU ISSUED A RECALL, BUT MY CAR IS NOT COVERED DUE TO MILEAGE, WHICH IS PROBLEMATIC.

ENGINE

THE CVT TRANSMISSION IS NOT OPERATING PROPERLY. THE CAR STALLS JUST PRIOR TO COMING TO A STOP. THIS IS VERY DANGEROUS IN TRAFFIC. THIS IS A KNOW PROBLEM BY SUBARU TO THE POINT THAT THEY ISSUED AN EXTENDED WARRANTY. THE PROBLEM IS THAT IT IS VERY DIFFICULT TO FIND ANY SUBARU DEALER WHO WILL PROPERLY DIAGNOSE THE PROBLEM TO ALLOW FOR WARRANTY COVERAGE. THIS SHOULD BE A RECALL GIVEN THE NUMBER OF VEHICLES REPORTING THIS PROBLEM AND THE UNSAFE CONDITION THAT IS CREATED.

ENGINE

WHEN COMING TO A STOP ON ANY ROAD THE VEHICLE STALLS, UPHILL OR DOWNHILL. THE CAR THEN NEEDS TO BE RESTARTED AFTER PUTTING THE VEHICLE IN PARK THEN TURNING THE KEY TO RESTART, AS VEHICLES ARE COMING QUICKLY FROM BEHIND. THIS COULD BE A POTENTIALLY DEADLY VEHICLE FAILURE AND NEEDS TO BE ADDRESSED AND RECALLED. IT STARTED ABOUT A WEEK AGO AND CONTINUES TO HAPPEN.

ENGINE

MY VEHICLE HEAD LIGHTS HAVE BURNT OUT AT LEAST ONCE A YEAR SINCE I HAVE OWNED THIS CAR. THE ENGINE HAS BEGAN STALLING WHEN I COME TO A FULL STOP. IT IS EQUIPPED WITH A CVT AND IT FEELS LIKE COMING TO A STOP IN A MANUAL TRANSMISSION WITHOUT DEPRESSING THE CLUTCH. IF I LET OFF THE BRAKE QUICKLY IT WILL CONTINUE IDLING BUT COMING TO A COMPLETE STOP KILLS THE ENGINE. I GUESS SUBARU HAS ISSUED AN EXTENDED WARRANTY BUT I NEVER RECIEVED THE NOTIFICATION AND MY VEHICLE IS PAST THE MILEAGE FOR THE WARRANTY ANYWAY.

DURING BRAKING, THE CAR OFTEN SHUTTERS AS IF IT IS GOING TO STALL, AND SEVERAL TIMES HAS STALLED COMPLETELY WHEN COMING TO A STOP. THIS OCCURS ESPECIALLY IF BRAKING HARD. THIS OCCURS ONLY WHEN THE CAR IS IN MOTION AND BEING BROUGHT TO A STOP. HOWEVER, WHEN IDLING, THE CAR OFTEN WILL SHUDDER AS WELL.

FROM 2010 - 2014, SUBARU REMOVED ENGINE TEMP. GUAGE FROM DASH SO THERE IS NO WAY TO MONITOR HIGH NORMAL TEMPS OF ENGINE. AT ONLY 93,770 MILES, MY 2010 OUTBACK 2.5L DASH COOLANT LIGHT FLICKERED ON A SLIGHT DOWNHILL. I HAD NEVER HAD AN ENGINE OR TRANSMISSION ISSUE WITH THIS CAR IN OVER 8 YEARS! TURNS OUT COOLANT WAS LOW DUE TO IT OVERHEATING AND BOILING OUT. TURNS OUT IT WAS THE BEGINNING OF A HEAD GASKET FAILURE! I COULD HAVE ENDED UP STRANDED ON THE SIDE OF A HILLY ROAD, WITH A BLOWN ENGINE! SUBARU HAS NOT FIXED THEIR CHRONIC HG FAILURE ISSUE!!! TO VERIFY/REPLICATE THE OVERHEATING, I TURNED ON THE A/C AND TOOK A 20 MILE OUT AND BACK ON A HILLY PORTION OF THE 5 FWY IN NORTHERN CA AT THEBEND OF SUMMER, 2018.

ENGINE

OCCASIONALLY THE 2.5 L ENGINE WITH CVT WILL APPEAR TO ALMOST STALL UPON DECELERATING AND COMING TO A STOP (AT A TRAFFIC LIGHT, STOP SIGN, ETC.). THE ENGINE WILL SHUDDER, THE RPMS WILL DROP BELOW 700 AND THEN QUICKLY RETURN TO NORMAL IDLE (ABOUT 800 OR SO). HAVE NOT YET EXPERIENCED A STALL BUT HAVE COME CLOSE. OUR CAR HAS ABOUT 87000 MILES AND IS OTHERWISE IN GOOD CONDITION. OUR MECHANIC HAS BEEN UNABLE TO DIAGNOSE THE PROBLEM BECAUSE THIS IS AN INTERMITTENT ISSUE, IT CANNOT BE DUPLICATED AND THERE ARE NO CODES. OTHER SIMILAR POSTS HAVE INDICATED THAT THE TORQUE CONVERTOR MAY BE THE CULPRIT. CONSIDERING THE QUANTITY OF POSTS, AN INVESTIGATION SHOULD BE UNDERTAKEN. STALLING CAN BE A SAFETY PROBLEM.

CAR FEELS LIKE IT'S GOING TO STALL OUT AT A STOP. THIS BEEN OCCURRING NOW FOR A YEAR. THE PROBLEM IS GETTING WORSE.
