2012 Subaru Outback Engine Problems

Just after 100k mile service, car began to shutter when slowing and then stalls at stops. Eventually after I leave it in neutral for up to 2-20 min it will finally restart. First time it happened it wouldn’t start. I had to push vehicle out of major intersection to avoid being hit then pay to tow it to nearest mechanic. Once there, it restarted and problem couldn’t be replicated nor did it relay any codes. Happened again the next two occasions I drove it so I immediately took it to Subaru dealer using side streets to avoid potential accident. After researching my model/year and symptoms, I found this was a common complaint with 2012 Outback’s and there have been numerous CVT issues. One of these issues is a faulty torque converter that causes stalling and usually appears around 100k mile mark (of course just shy of warranty). In 2017 (prior to owning car) a bulletin was released notifying dealers of issue which led to extension of warranty due to customer complaints. Given this new information, I was not shocked when dealer diagnosed my car as needing a new torque converter. Had I known this was an issue beforehand, I would have requested an inspection when spending thousands for 100k mile maintenance. I even brought vehicle to same Subaru dealer years prior (when it would have still been under warranty) for noise and shaking when accelerating/braking. They said this was normal for box engines and test drove it without any concerns. I can’t believe with the vast complaints on CVT issues that Subaru has not issued a recall. It’s irresponsible, dishonest, and a major safety concern. Consumers have right to be notified if they may be affected or put at risk.

No issues with the car since I bought it new and was dedicated to regular Maintenance. Less than a week after a regular scheduled oil change and driving on the main interstate highway cruising at 65mph, the car just suddenly jerked. I thought I had blown a tire but the Brake light came on and then soon after the engine light came on. I was able to get off the highway but the acceleration decreased to a slow crawl. I had it towed to the nearest Subaru dealership that morning in which they said the issue is that both 1 and 4 are not correctly firing. They checked the spark plugs and checked the injector, but both did not fix the issue. They have now told me that they need to get the engine pistons/valves "machined". They are reaching out to Subaru to see if they can help since there is nothing I could have done to prevented this issue and they are hearing more of this issue occurring in Subaru cars. I'm praying that Subaru will help me with my vehicle but am waiting to hear from the Subaru dealership.

TL* THE CONTACT OWNS A 2012 SUBARU OUTBACK. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 35 MPH AND RELEASING THE ACCELERATOR PEDAL, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS RESTARTED. THE VEHICLE WAS TAKEN TO DEWEY GRIFFIN SUBARU (1800 IOWA ST, BELLINGHAM, WA 98229, (360) 734-8700) BUT WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 155,000. THE VIN WAS NOT AVAILABLE.

THE VEHICLE STALLS COMPLETELY UPON SLOWING DOWN. THIS OCCURS FREQUENTLY AT STOP SIGNS, LIGHTS AND WHILE CROSSING A MAJOR ROAD AND WAITING HALFWAY ACROSS TO JOIN THE FLOW OF TRAFFIC. SUBARU DEALER SAYS IT IS A DEFECTIVE TORQUE CONVERTER BUT NO LONGER COVERED BY THE CVT WARRANTY EXTENSION. THIS IS EXTREMELY DANGEROUS AND SHOULD BE FIXED AT NO COST TO VEHICLE OWNER.

ON OCTOBER 16TH, 2020 WHILE DRIVING OUR 2012 SUBARU OUTBACK ON THE HIGHWAY, THE CHECK ENGINE LIGHT CAME ON. MY HUSBAND AND I PULLED OVER, LIFTED THE HOOD AND SAW STEAM COMING FROM THE ENGINE NEAR THE RADIATOR. WE TOOK THE CAR TO THE SUBARU DEALERSHIP AND THE TECH STATED BOTH HEAD GASKETS WERE FAILING. THE VEHICLE HAD 156,000 MILES ON IT AND WE ENDED UP PAYING OVER $2500 IN REPAIR COSTS. BECAUSE OF THE AGE AND MILEAGE ON THE CAR, I DID NOT PLAN TO SUBMIT A REPOT TO THE NHTSA. HOWEVER, I WAS NOTIFIED BY A RELATIVE TODAY THAT HER 2009 SUBARU IMPREZA WITH ONLY 68,000 MILES JUST EXPERIENCED HEAD GASKET FAILURE AND THE DEALERSHIP QUOTED HER $4500 IN REPAIR. I HAVE ENCOURAGED HER TO SUBMIT THE ISSUE THROUGH NHTSA FOR FURTHER TRENDING PURPOSES AS I BELIEVE THIS MAY BE A SAFETY CONCERN WITH SUBARUS.

WHEN I BE DRIVING, AND APPROACHING AN INTERSECTION, OR A STOP. MY CAR STALLS OUT. THIS HAPPENS MORE OFTEN, WHEN A DO A QUICK STOP. I BEGAN,NOTICING THIS CONDITION ABOUT A FEW MONTHS AGO,,APPROXIMATELY JANUARY 2020. *TR

The contact's girlfriend owns a 2012 Subaru Outback. The contact stated that the vehicle hesitated while starting. In addition, the contact attempted to jumpstart the vehicle; however, the vehicle failed to start. The check engine warning light was intermittently illuminated. The contact stated that during rainy weather, several unknown warning lights were illuminated. The contact scanned the vehicle with an OBD2 scanner and retrieved DTC codes: P0420 (Catalytic convertor) and P0057 (Ignition System). The vehicle was taken to a local dealer to be diagnosed. The contact was informed that there were failures with the rear brake pads, rotors, PCV valve, valve cover gasket, engine air filter, catalytic converter heat shield; and a cylinder #4 misfire. The DTC codes P0304, and P0420 (Catalytic convertor) were also retrieved. The contact was informed that the catalytic converter needed to be replaced first. The contact stated that several repairs were made prior; however, the failure persisted. Upon further investigation, the contact related the failure to Subaru Service Program Bulletin: WQC-39, WVY-35, WUF-91r, TKC-19R, and NHTSA Campaign Number: 20V003000 (Air Bags); however, the VIN was not included. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 97,803.

THE VEHICLE STALLS AND ABRUPTLY STOPS. THIS IS APPARENTLY A KNOWN PROBLEM WITH THIS CAR, BUT THE DEALERSHIP IS DEMANDING $1300 TO FIX IT SINCE I'M OUT OF THE WARRANTY PERIOD. THIS SHOULD NOT BE JUST A EXTENDED WARRANTY - THIS IS A SAFETY ISSUE: THE VEHICLE STALLS IN TRAFFIC. IT CANNOT BE DRIVEN IN THIS CONDITION. TODAY IT STALLED IN THE MIDDLE OF A HIGHWAY INTERSECTION WHERE I WAS TURNING. I HAD A SEMI TRUCK BARRELLING DOWN AT ME ON AN ICY ROAD WHILE I DESPERATELY TRIED TO RESTART THE CAR AND GET OUT OF THE INTERSECTION. THE SEMI SWERVED AND BARELY MISSED ME. THESE CARS SHOULD BE RECALLED!

WHILE ON A 200 MILE TRIP ON RURAL INTERSTATE THE THERMOSTAT FAILED CAUSING HEAD GASKET TO BLOW AND ENGINE TO OVERHEAT. NO CHECK ENGINE WARNING LIGHT WAS DISPLAYED. SUDDENLY ALL CONTROL PANEL WARNING LIGHTS BEGAN TO FLASH. ALL COOLANT WAS EXPELLED FROM RADIATOR. VEHICLE HAS LESS THAN 100K MILES. BY SHEAR LUCK I WAS AT AN EXIT WITH A SUBARU DEALER NEAR BY. HAVE ATTACHED REPAIR REPORT FROM SUBARU DEALER.

ENGINE SHUDDERS THEN SHUTS OFF WHEN STOPPING. FREQUENTLY OCCURS WHEN COMING TO A STOP ON A CURVED ROAD NEAR MY HOME. VERY CONCERNED ABOUT BEING REAR-ENDED. I HAVE TO THROW THE CAR IN PARK, RESTART AND THROW IT BACK IN DRIVE. DEALER REPLACED OIL SOLENOID VALVE FOR $350 AND IT DIDN'T FIX THE PROBLEM. NOW THEY WANT OVER $1500 TO REPLACE THE TORQUE CONVERTER. THEY SAY IT IS A KNOWN PROBLEM AND I HAD UNTIL JULY 2018 UNDER AN EXTENDED WARRANTY TO TAKE CARE OF IT. I WAS NEVER NOTIFIED. I FEAR SPENDING ANOTHER $1500 WILL NOT FIX THE PROBLEM. I OWE ANOTHER YEAR OF PAYMENTS ON THIS VEHICLE AND I DON'T FEEL SAFE DRIVING THE SUBARU. MILEAGE IS AROUND 155,000.

TL* THE CONTACT OWNS A 2012 SUBARU OUTBACK. WHILE THE VEHICLE WAS IDLING AT A RED LIGHT OR AN INTERSECTION, IT WOULD STALL INTERMITTENTLY WITHOUT WARNING. WHEN THE VEHICLE WAS POWERED OFF AND RESTARTED, IT OPERATED NORMALLY. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO TACOMA SUBARU (LOCATED AT 3838 S TACOMA WAY, TACOMA, WA 98409, (253) 473-6200) WHERE IT WAS DIAGNOSED THAT THE TORQUE CONVERTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 115,000.

MY CAR SHUDDERS AND DIES WHEN BRAKING. IT DOESN'T EVEN HAVE TO BE A HARD BRAKE. IT'S VERY DANGEROUS. THIS PROBLEM HAS BEEN OCCURRING IN THE LAST FEW MONTHS. IT HAPPENS WHILE I AM SLOWING FOR A STOP. MY MECHANIC TELLS ME IT IS RELATED TO THE TORQUE CONVERTER, WHICH IS EXPENSIVE TO FIX. I AM AFRAID THAT I WILL BE REAR-ENDED. WITH HIGHWAY DRIVING THIS IS UNBELIEVABLY DANGEROUS. I KNOW THAT SUBARU EXTENDED THE WARRANTY ON THIS ISSUE--ALTHOUGH I ONLY KNEW OF THIS BECAUSE MY MECHANIC TOLD ME. UNFORTUNATELY MY CAR JUST WENT OVER THE 100,000 MILE MARK, SO I'M UNSURE IF SUBARU WILL COVER THE REPAIR NEEDED. I REALLY BELIEVE THIS ISSUE SHOULD PROMPT A RECALL. SOMEONE IS GOING TO GET SERIOUSLY INJURED OR DIE.

WHEN BRAKING TO COME TO A STOP AT A LIGHT ON A SECONDARY ROAD OR STOP SIGN ON MY BACK STREET IN A STRAIGHT LINE THE ENGINE STALLS, THIS HAS EVEN HAPPENED WHEN I HAD TO BRAKE TO STOP FOR BACKED UP TRAFFIC ON THE HIGHWAY. THIS HAS HAPPENED AT LEAST FOUR TIMES IN THE PAST AND AGAIN THIS MORNING. I TOLD MY DEALERSHIP SEVERAL TIMES AFTER THE PURCHASE OF THIS VEHICLE I NOTICED IDLE WOULD DROP OUT AND COME BACK WHILE AT A STOP, BUT I WAS TOLD THERE WAS NOT AN ISSUE. I NOW READ THIS IS NOT TRUE AND HAS BEEN AN ON GOING ISSUE WITH THIS MANUFACTURER FOR SOME TIME AND IS A WIDE SPREAD ISSUE WITH THE CVT. THE EXTENDED WARRANTY OFFERED AND NOW EXPIRED BY SUBARU NEVER MENTIONED THE POSSIBLE SAFETY ISSUE OF STALLING DUE TO A FAULTY CVT, BUT ACTUALLY SEEMED TO SAY THIS EXTENDED WARRANTY ONLY APPLIED TO SHIFTING ISSUES SO I IGNORED IT AS THE CAR SHIFTED FINE BOTH AUTOMATICALLY AND MANUALLY AS DESIGNED. I FEEL VERY MISLED AND LET DOWN BY SUBARU WHO I ALWAYS THOUGHT WOULD PUT THE SAFETY OF THEIR CUSTOMERS FIRST, I GUESS NOT.

5 DAYS AFTER 120K MILE DEALER SERVICE (ALL WORK IS DONE BY SUBARU DEALER WHERE WE PURCHASED) MORE DASH LIGHTS THAN WHAT SULLY SULLENBEGER HAD TO CONTENT WITH. OCCURRED WHILE SITTING IN TRAFFIC IN 90 DEGREE HEAT (WITH A 6 MONTH OLD IN THE CAR). DROVE IT 35 MILES TO GET IT TO THE DEALER. $2200 ESTIMATE TO REPLACE 2 HEAD GASKETS. DEALER IS TAKING $350 OFF. WORTH TALKING TO SUBARU CORP ABOUT ADDED COMPENSATION FOR A KNOW DEFECT? I SEE THE SAME ISSUE REPORTED ON LINE SHORTLY AFTER THE 100K OR 120K MILE DEALER CHECK UP.

MY WELL-MAINTAINED SUBARU OUTBACK LIMITED WITH 102,773 MILES OVERHEATED AND BLEW A HEAD GASKET OUT OF THE BLUE. JUST HAD THE MAJOR 100K MILE PREVENTIVE MAINTENANCE DONE TOO. THE EXTENDED WARRANTY JUST EXPIRED AT 100K AND THE DEALER SAYS IT WILL BE OVER $3K TO REPAIR. APPARENTLY THIS IS A COMMON PROBLEM WITH SUBARUS THAT THEY HAVE FAULTY HEAD GASKETS THAT FAIL BETWEEN 80-120K MILES. VERY DISAPPOINTED WITH SUBARU QUALITY WITH SUCH A MAJOR ISSUE AT HALF LIFE OF MY OTHERWISE RELIABLE VEHICLE!

TL* THE CONTACT OWNS A 2012 SUBARU OUTBACK. WHILE DRIVING AT AN UNKNOWN SPEED, THE VEHICLE SHUTTERED AND STALLED WITHOUT WARNING. THE VEHICLE WAS TOWED TO MASTRIA SUBARU (1255 NEW STATE HWY, RAYNHAM, MA 02767) WHERE IT WAS DIAGNOSED THAT THE ENGINE WAS BURNING OIL. THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 145,459.

ENGINE LOCKED UP TRAVELLING 80 MPH ON THE HIGHWAY. THE ENGINE HAD 90,000 MILES ON IT AND IT WAS FULLY SERVICED AT 88,000 MILES BY A DEALERSHIP. NOTES FROM THE DEALERSHIP SERVICE DEPARTMENT: 'MOTOR CAME APART AT HIGH REV SPEED, 1 PISTON CRACKED, 1 PISTON GONE. EXCESSIVE METAL SCATTERED THROUGH COMPLETE ENGINE AND INTAKE MANIFOLD' "THE ENTIRE MOTOR (BLOCK, HEADS, VALVES, CAMSHAFTS, INTAKE MANIFOLD, ETC.) WILL NEED TO BE REPLACED DUE TO METAL DEBRIS THROUGHOUT MOTOR."

ENGINE SHUDDERS, OR COMPLETELY STALLS AT A SUDDEN BRAKE TO STOP COMPLETELY. DRIVER MUST PUT VEHICLE IN NEUTRAL OR PARK TO RE-START THE ENGINE. **** THE PROBLEM DESCRIBED BEGAN A YEAR AGO. DRIVER NOTICED VEHICLE WOULD SHUDDER OCCASIONALLY AT A COMPLETE STOP. THE FIRST TIME THAT THE ENGINE COMPLETELY DIED, DRIVER THOUGHT IT MAY HAVE BEEN DUE TO WEATHER. THIS SHUDDERING AND STALLING BEGAN OCCURRING MORE AND MORE FREQUENTLY IN ALL WEATHER CONDITIONS CREATING A SAFETY HAZARD. WHEN DRIVER NOTICES THE SHUDDER, IF THE BRAKE PEDAL IS EASED UP, NORMAL RPMS RETURN. THE ENGINE WILL ALSO SOMETIMES SHUDDER DURING A TIGHT TURN AS WELL. WHILE TESTING DURING DRIVING/BREAKING THIS MORNING DRIVER MAINTAINED A SPEED OF 55 MPH FOR 1 MILE. DRIVER BEGAN BRAKING THE VEHICLE AT THE DISTANCE BETWEEN 2 LIGHT POLES (ON A COUNTRY ROAD) AND CAME TO A COMPLETE STOP WITH THE VEHICLE STRAIGHT FORWARD. ENGINE DIED. THE 2ND TIME THIS WAS TESTED, SAME SPEED SAME BRAKING DISTANCE, THIS TIME THE DRIVER WAS GOING TO MAKE A RIGHT TURN, SO UPON BRAKING THE VEHICLE WAS TURNED AT A 45 ANGLE. THE ENGINE DIED. WARNING LIGHTS: VEHICLE DYNAMICS, CHECK ENGINE, AWD, CHARGE WARNING (BATTERY) , AND OIL PRESSURE. THE CD PLAYER STAYED ON, THE FAN FOR HEAT/AC TURNED OFF.

3.6 ENGINE USES 1/2 QUART OIL AFTER 3000 MILE OIL CHANGE. CAR HAS ALWAY HAD 5W30 MOBILE 1 OIL USED IN IT SINCE WE HAD THE CAR. HAD SOME MINOR OIL CONSUMPTION AT FIRST BUT NOW IT IS BECOMING MORE COMMON. DEALERSHIP SAID IT CAUSE THE OIL MANUFACTURES ARE MAKING THE OIL THINNER SO THAT IS CAUSING THE PROBLEM? SORRY I WAS NO NOT BORN YESTERDAY. 2 REASONS FOR OIL CONSUMPTION THAT I KNOW IS A OIL LEAK OR DEFECTIVE PISTON RINGS WHICH SUBARU HAS HAD ISSUES WITH ON OTHER MODEL CARS.

WE WERE NEVER NOTIFIED OF A EXTENDED WARRANTY ON THE CVT OF OUR OUTBACK. WE TOOK IT TO SUBARU DEALERSHIPS FOR MAINTANCE AND THEY FAILED TO TELL US ABOUT THE CVT GOING BAD CAUSING DAMAGE TO THE TRANSMISSION. WHEN WE CONTACTED SUBARU CORPORATE THEY TOLD US THERE WAS NOTHING THEY COULD DO. NOW WE HAVE HAD THE CAR LOOKED AT WHEN IT WAS UNDER THE MILEAGE BECAUSE IT WAS SHOWING SIGNS OF THE CVT GOING BAD AND THE DEALERSHIP WAS NEGLIGENT IN LETTING US KNOW OF THE PROBLEM. NOW WE FEEL OUR VEHICLE IS UNSAFE TO DRIVE AND SUBARU IS NOT WILLING TO FIX THE PROBLEM THEY KNEW ABOUT. WHEN WE FILL OUR TANK UP AT THE GAS STATION THE BREAK, TRACTION, CRUISE CONTROL LIGHTS WILL BLINK AND THE CRUISE CONTROL WILL STOP WORKING WHILE THE LIGHTS ARE BLINKING. WE TOOK THE CAR TO DERREL WALTRUP DEALERSHIP IN NASHVILLLE TENNESSEE, SUBARU OF NASHVILLE AND SUBARU OF GALLITAN TN. ALL THREE DEALERSHIPS AGEED THAT THE ISSUE WITH OUR CAR IS DUE TO THE CVT WARRENTY ISSUE. WE ARE THE ONLY OWNERS OF THIS SUBARU AND HAVE TAKEN GREAT CARE OF IT. WE WANT SUBARU TO STAND BEHIND THEIR PRODUCT AND FIX THE DEFECT SO THAT WE CAN CONTINUE TO BE SAFE IN OUR CAR.
