2015 Subaru Legacy Fuel system Problems

I am reporting a Sudden Unintended Deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.

DRIVING ON INTERSTATE AT 70MPH & CAR ACTED AS IF IT WENT INTO NEUTRAL. RPM'S WERE MAINTAINED AT APX 4000. LOW FUEL LIGHT HAD JUST GONE MOMENTS BEFORE INDICATING 80 MILES LEFT IN TANK. CAR ACTED LIKE IT HAD NO GAS HOWEVER RPM WAS WORKING AS I PULLED ON TO SHOULDER OF HIGHWAY, LUCKILY.ONCE PULLED OVER & BRAKING ENGINE STOPPED. TRIED RESTARTING & ENGINE ACTED LIKE IT HAD NO GAS. WAS IN THE PROCESS OF WAITING FOR AAA WHEN I TRIED RESTARTING IT. IT STARTED AFTER ABOUT A HALF HOUR FROM INCIDENT, ALTHOUGH I DID NOT TRY TO START IT AFTER THE 1ST 5 MINUTES OR SO. WHEN IT RESTARTED LOW FUEL GAUGE WAS STILL ON 70 MILES TO EMPTY & I WAS ABLE TO MAKE IT TO GAS STATION & REFUELED TO APPROXIMATELY 15 GALLONS, 3 LESS THAN 18 GALLON TANK SO THERE WAS APPROX 3 GALLONS IN TANK WHEN THIS OCCURRED. CAR IS WORKING FINE NOW BUT WILL BE TAKING TO NC SUBARU TO SEE IF ANY CODES WERE SET, NOTHING WAS ALERTED ON CAR WARNING LIGHTS OTHER THAN LOW FUEL WARNING LIGHT. I LIVE IN NJ & I AM CONCERNED THIS COULD HAPPEN AGAIN DRIVING BACK & I MAY NOT BE SO LUCKY TO BE ABLE TO PULL OVER ON MORE CONGESTED HIGHWAYS. SEARCHED GOOGLE & THERE ARE SIMILAR INCIDENTS SUCH AS SUBARU FORRESTOR 2014 WITH SAME ENGINE & ISSUE WHERE DEALER COULD NOT FIND ISSUE. ALSO SUBARU ISSUED RECALL FOR 2017 IMPREZZA (SEE 33K CARS RECALLED) WITH STALLING ISSUES. CAR HAS 93K MILES & OTHER THAN REPLACING 2 BATTERIES, ONE A FEW WEEKS BACK , IT HAS NEVER HAD AN ISSUE WITH ANYTHING ELSE. I WAS APPROXIMATELY 2 MILES FROM GETTING OFF INTERSTATES WHEN THIS OCCURRED (EG 553 OF 550 MILES BEFORE 30 OR SO MILES REMAINING ON LOCAL ROADS). AFTER REFUELING IN NJ ONLY MADE TWO QUICK 5 MINUTE STOPS ALONG THE WAY BEFORE THIS OCCURRED.

SINCE NOVEMBER OF 2017 WHILE DRIVING THE CAR IT HAS INTERMITTENTLY JERKED AND SHOOK EXCESSIVELY, BUCKING LIKE A MAD HORSE. CAR WAS BROUGHT IN TO DEALER FOR DIAGNOSIS. DEALER WAS NOT ABLE TO IDENTIFY THE CAUSE. AFTER SEVERAL VISITS TO DEALER WHERE I WAS ASSURED THE PROBLEM WAS FIXED THE SAME PROBLEM CONTINUED. IT SHOULD BE NOTED THAT THE CAR, WHILE DRIVING STARTED TO SHUT DOWN AND I NEEDED TO BE TOWED TO THE DEALER. DEALER CLAIMED THE PROBLEM WAS A FAULTY SPARK PLUG. CAR WAS THEN RETURNED TO ME. YET AGAIN THE PROBLEM PERSISTED AND HAD I TO CRAWL LIKE A TURTLE BACK TO HOME. CAR WAS TOWED AGAIN TO DEALER FOR ANOTHER DIAGNOSIS. NOW THE DEALER BELIEVES THE PROBLEM IS A FAULTY CYLINDER (WHATEVER THAT MEANS).I HAVE NO TRUST IN THE RELIABILITY OF THIS VEHICLE AND AM CONCERNED ABOUT THE SAFETY OF DRIVING THIS VEHICLE WITH MY FAMILY. IT BE SHOULD BE NOTED THAT THE CAR HAS BEEN SERVICED EXACTLY TO THE INSTRUCTIONS PER THE MILEAGE GUIDANCE. I HAVE REPORTED THIS CONCERN TO SUBARU OF AMERICA CORPORATE OFFICE. CASE # 1-38872409282. THEIR RESPONSE IS UNFAIR. I AM NOW LEFT WITH A CAR THAT IS UNSAFE TO DRIVE AND I SHOULD NOT BE PENALIZED FINANCIALLY.

MY 2015 SUBARU LEGACY HAS AT DIFFERENT TIMES (AT IDLE IN GEAR, COMING UP TO A RED LIGHT WHILE MOVING, PULLING INTO A PARKING LOT OR DRIVING AT 45 MILES AN HOUR) ACCEREATED ON ITS OWN AND WOULD NOT SLOW DOWN UNTILL I PUT IT IN NUETRAL. I HAVE TO DRIVE WITH MY HAND ON THE SHIFTER AT ALL TIMES TO PUT INTO NUETRAL. I BOUGHT THE CAR NEW IN 2015 AND HAVE 13900 MILES ON IT NOW IN JULY 2016.

GAS CAP LID DOES NOT OPEN. WE TOOK THE AUTO INTO DEALERSHIP JUNE 30, 2015 AND GAVE THEM TSB-09-60-15. MILEAGE 5987. TEMPS IN THE 70'S. THEY GREASED THE GAS LID CONTACT. I INDICATED THE TSB INDICATED SOMETHING OTHER THAN THAT. THEY TOOK BACK INTO SHOP AND GROUND DOWN THE LID RELEASE CONTACT. DROVE HOME. TRIED TO OPEN GAS CAP LID AND IT WOULD NOT OPEN. WE ARE CONCERNED ABOUT DRIVING AUTO ANY DISTANCE BY ONESELF BECAUSE IT NOW TAKES TWO PEOPLE TO PUT GAS INTO AUTO. ONE TO PULL UP LEVER AND ONE TO PRY OPEN THE LID ON THE OUTSIDE. I AM SEEING NUMEROUS PROBLEMS WITH SEVERAL OTHER SUBARU MODELS BESIDES THE LEGACY. SUCH A SIMPLE MANUFACTURING FLAW SHOULD BE ABLE TO BE FIXED. LOVE THE AUTO BUT THIS IS REALLY REALLY AN ANNOYING SIMPLE FLAW. ONE PERSON'S COMMENT ON A TSB PERTAINING TO THIS ISSUE SAID IF THE LUBE AND GRINDING DOES NOT FIX THE ISSUE, THE ENTIRE CAP ASSEMBLY NEEDS TO BE REPLACED. I HAVE NOT DISCUSSED THIS WITH THE DEALER YET. THIS ISSUE HAPPENS IN ALL TEMPS. CURRENTLY 60 IN GARAGE AND CAP DOES NOT OPEN. MILEAGE 10365.

AT THE FIRST REFUELING OF THE CAR AFTER PURCHASE, THE FUEL DOOR DID NOT OPEN WHEN THE LEVER WAS PULLED. EVENTUALLY IT DID OPEN AFTER MULTIPLE ATTEMPTS. AT THE SECOND REFUELING OF THE CAR, APPROXIMATELY 450 MILES AFTER THE FIRST TIME, ONCE AGAIN THE DOOR DID NOT OPEN. IT OPENED FINALLY AFTER ABOUT 10 MINUTES WITH ONE PERSON OPERATING THE LEVER AND ANOTHER FORCING THE DOOR. THE NEXT DAY, THE CAR WAS TAKEN TO THE DEALERSHIP WHERE THE FUEL DOOR PIN WAS ADJUSTED TO RECTIFY THE PROBLEM.

ALMOST EVERY TIME I FILL UP WITH GAS, WHEN THE GAS PUMP SHUTS OFF THERE IS A BACK SPLASH OF GAS OUT OF THE TANK. I WOULD SAY ANYWHERE FROM 1 TO 3 OUNCES OF GAS SPLASHES OUT. DEPENDS ON THE PRESSURE IT'S BEING FILLED AT. I TALKED TO MY DEALER ABOUT IT AND WAS TOLD THAT IS COMMON FOR SUBARU LEGACY'S. *TR
