2015 Subaru WRX Engine Problems

My engine starting making like a clunking sound I always have took my car for service at the dealership i own the 2015 subaru wrx premium i haven’t move the car after the noise due to scare I might mess something with the engine

Engine has rod knock present common amongst owners. Short block replaced under warranty at 55k miles. How can a stock engine with synthetic oil changes commonly fail? Flaws.

The secondary o2 pump will burn out or continue running causing unsafe risk to short circuit a fire. Recall has already been previously documented in the -2014 models however Subaru uses the same design and part number. My car Secondary o2 Pump was replaced under warrenty at 55k miles now at 90knmiles have the same CEL code.

Turbocharger intake cracked and causes the engine to have an extremely rough idle and stall. My vehicle has the same issue as NHTSA campaign number 16V16200 however it was manufactured before April 10th 2015 so it is not included in that recall.

-Engine Head Gasket (Blown), Yes. -Engine coolant created cloud of white vapor while driving, impairing ability to visually assess the road. Leaked hazardous fluid over freeway possibly contaminating soils and affecting local wildlife. -The problem has been reproduced and confirmed by Eastside Subaru in Kirkland, WA. -The vehicle has been inspected by Eastside Subaru in Kirkland, WA. -There was no warning (check engine lights) until the incident occurred.

I OWN A 2015 WRX LIMITED CVT. WHEN I GO TO MY CAR TO GO TO WORK AND I START IT, THE CAR SPUTTERS. I'VE ONLY NOTICED THIS ON COLD STARTS ONLY, ONCE THE CAR IS WARMED UP IT'S FINE. FOR SOME REASON THOUGH WHEN THE CAR IS SPUTTERING ON START UPS IT WILL TRIP MY CEL AND BASICALLY PUT THE CAR INTO 'GET HOME' MODE, BUT IT ONLY SEEMS TO TRIGGER THE CEL WHEN IT WANTS TO. THE CAR WILL ALWAYS SPUTTER ON START UP BUT SOMETIMES THE CEL WILL COME ON AND I CAN'T USE THE DRIVE MODES AND SOMETIMES IT WON'T COME ON. NO MATTER WHAT I DO I CAN'T GET THE CAR TO STOP SPUTTERING. I'VE CLEANED PRETTY MUCH EVERY SENSOR I COULD AND NOTHING WORKED. I SCANNED THE OBD2 PORT AND GOT P0300 FOR RANDOM MISFIRE, WHICH TELLS ME ABSOLUTELY NOTHING.

THE RPM DROP AND THE ENGINE STALLS, BUT NO CHECK ENGINE LIGHTS COME ON. IT ONLY HAPPENS IN FIRST GEAR, FROM WHAT I'VE NOTICED.

DECIDED TO GET MY SPARK PLUGS REPLACED, AND GOT A COMPRESSION TEST DONE WHILE THAT SERVICE WAS DONE FOR CONVENIENCE. COMPRESSION CAME OUT LOW ON ONE SIDE OF MY FA20DIT ENGINE. WITH MORE RESEARCH, BECAUSE THE ENGINE IS DIRECT INJECTED, THERE IS OBVIOUS BUILD UP ON THE INTAKE VALVES, CAUSING BAD AIR FLOW. THIS IS NOT A WEAR AND TEAR ISSUE.

VEHICLE HAD A BRAND NEW SHORT BLOCK WITH APPROXIMATELY 6,000 MILES ON IT, AND SPUN A BEARING.

IN A 2015 SUBARU WRX WITH A 6-SPEED MANUAL TRANSMISSION PURCHASED 03/2015 AND DELIVERED TO PURCHASE DEALER 04/2015.

DIAGNOSTIC CODE P0420 REPORTED A FAULT IN CATALYTIC CONVERTER. SOFTWARE UPDATE TO COMPUTER PERFORMED RESOLVED ISSUE TEMPORARILY. 04/10/2016 AT 9.7K MILES ROUGH IDLE ISSUE RETURNED RPMS OF 400 TO 1K AGAIN AFTER FUELING. IN NEUTRAL 30-60 SECONDS AFTER STARTING VEHICLE STALLED AT FUEL STATION. UPON RE-STARTING VEHICLE CHECK ENGINE, FLASHING CRUISE CONTROL, ABS, HILL-START ASSIST, AND TRACTION CONTROL FAULTS TRIPPED. VEHICLE BEHAVIOR SIMILAR TO NHTSA RECALL 16V-162 WHERE NHTSA NOTED 'DUE TO THE USE OF INCORRECT MATERIAL FOR A PORTION OF THE ENGINE TURBOCHARGER AIR INTACT DUCT CRACK, THE ENGINE MAY DEVELOP A ROUGH IDLE, REDUCED POWER, AND POSSIBLY STALL'. COMPLAINANT BELIEVES RECALL MAY NEED TO BE EXPANDED TO INCLUDE A WIDER RANGE OF VINS BEFORE LISTED PRODUCTION DATES IN RECALL ORDER.
