There are 2 owner-reported engine complaints for the 2014 Subaru WRXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
AT APPROXIMATELY 34,000 MILES WHILE IN A DRIVING TO WORK I STARTED HEARING A KNOCKING NOISE BY THE TIME I MADE THE 5 MILE JOURNEY TO WORK THE KNOCKING HAD GOTTEN SO BAD, THAT I HAD TO HAVE IT TAKEN TO THE DEALERSHIP. THE OIL WAS JUST CHANGED AT THE DEALERSHIP TWO DAYS BEFORE AND WAS STILL FULL. THEY SUBARU DEALERSHIP WOULD NOT WARRANTY THE MAIN BEARING OR ROD KNOCK FAILURE THAT OCCURRED. WHEN I CONTACTED SOA, THEY WERE ALSO NOT ABLE TO HELP. THE DEALERSHIP QUOTED ME ROUGHLY $7,800.00 TO COVER A COMPLETELY NEW SHORT BLOCK. I ONLY HAD THE CAR FOR 3 MONTHS. THIS SEEMS TO BE A REOCCURRING ISSUE WITH MY MODEL OF WRX. I HAD TO SHELL OUT MORE THAN $8,000.00 TO REPLACE THE ENGINE WITH BETTER MORE RELIABLE PARTS BY A PRIVATE PARTY, BECAUSE I DID NOT TRUST THE DEALERSHIPS OR SOA.
ENGINE EXPERIENCED ROD BEARING FAILURE ON TWO ROD BEARINGS. WAS TRAVELING DOWN HIGHWAY WHEN ENGINE DIED. COASTED OFF OF THE HIGHWAY AND STOPPED. WHEN TRYING TO RESTART THE VEHICLE, THE ENGINE WAS HARD TO TURN OVER, AND KNOCKED WHILE RUNNING AFTER IT STARTED.
