MY 2009 SUBARU IMPREZA WRX, WHICH I USE AS A DAILY DRIVER, HAD A MAJOR ENGINE BREAKDOWN AT ABOUT 9000 MILES CONSISTING OF A LOUD KNOCKING SOUND AND EXTREME ENGINE VIBRATION. THE SYMPTOMS WERE CONFIRMED BY MY DEALER AS A SPUN ROD BEARING (#4). MY ENGINE AND TURBOCHARGER WERE REPLACED UNDER WARRANTY (AFTER A 24 DAY WAIT). SCHEDULED MAINTENANCE HAD BEEN DONE PRIOR TO THE FAILURE (OIL CHANGES). WHILE THE FAILURE DID NOT CAUSE AN IMMEDIATE SAFETY SITUATION, AS I WAS VERY CLOSE TO HOME AT THE TIME, I FEEL THAT AN ISSUE LIKE THIS COULD PRESENT AN UNSA…

I PURCHASED A 2009 SUBARU IMPREZA WRX (BUILD DATE OF 07/08) IN SEPTEMBER, 2008. ON DECEMBER 12, 2008 (W/ APPROX 3870 MILES ON THE ODOMETER) DURING MY COMMUTE LEAVING WORK UPON MERGING INTO TRAFFIC THE VEHICLE EXHIBITED A SUDDEN LOSS OF POWER. THANKFULLY AT THIS TIME TRAFFIC WAS LIGHT AND THERE WAS NO ACCIDENT. THE VEHICLE AT THIS TIME EXHIBITED A RATHER PRONOUNCED CYCLIC KNOCKING SOUND AND HARSH VIBRATION. I WAS ABLE TO LIMP THE VEHICLE TO THE HOME OF A FAMILY MEMBER (VEHICLE AT THIS POINT HAD 3892 MILES ON THE ODOMETER); SHORTLY THEREAFTER…
THERE WAS NO INDICATION THAT A FAILURE WAS GOING TO OCCUR BEFORE IT HAPPENED. I HAD DRIVEN THE CAR NORMALLY FOR ALMOST 6 MONTHS. THE ENGINE BEGAN TO MAKE A LOUD KNOCKING NOISE AROUND 2000 RPM, SOUNDING LIKE METAL HITTING METAL. LUCKILY FOR ME, I WAS APPROACHING A PARKING LOT SO I WAS ABLE TO PULL OVER AND HAVE MY CAR TOWED. I WAS TOLD THAT IF I HAD KEPT DRIVING THE CAR WOULD HAVE JUST STOPPED FUNCTIONING ENTIRELY AND LEFT ME STRANDED WHEREVER IT DIED. THE FAILURE, WHICH TURNED OUT TO BE A SPUN BEARING IN THE 2ND PISTON, WAS RECTIFIED BY RE…

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

TL*THE CONTACT OWNS A 2009 SUBARU IMPREZA WRX. HE STATED THAT WHILE DRIVING 40 MPH THE ENGINE STARTED TO MAKE A NOISE WHILE APPROACHING A STOP SIGN AND SHUT OFF. HE WAS ABLE TO RESTART THE VEHICLE AND DRIVE TO AN AUTHORIZED DEALER; HOWEVER, THE NOISE BECAME LOUDER AND MORE FREQUENT AND THE VEHICLE CONTINUED TO STALL. THE VEHICLE WAS TOWED TO THE DEALER AT THEIR EXPENSE. THE DEALER CONFIRMED THAT THE ENGINE WAS DESTROYED AND COULD NOT BE REPAIRED. THE DEALER ALSO STATED THAT BEFORE THE VEHICLE LEFT THE FACTORY THAT THE ENGINE WAS NOT INSPECTED…
