2008 Subaru Impreza Sti

MY 2008 SUBARU IMPREZA WRX STI HAD A NUMBER FOUR PISTON FAILURE WITH ONLY 28,000 MILES ON THE VEHICLE. THE VEHICLE WAS IMMEDIATELY TAKEN TO A LOCAL AUTO SHOP WHEN A PROBLEM WAS NOTICED. THE SHOP DID A COMPRESSION TEST AND FOUND THE NUMBER FOUR PISTON TO BE AT FAULT. DUE TO THE POSSIBILITY OF DAMAGE TO THE CYLINDER WALLS THE BLOCK AND ALL ASSOCIATED INTERNALS WERE REPLACED. AFTER REMOVING THE HEADS THE SHOP OWNER SAID THERE WERE NO SIGNS OF DETONATION ON THE CYLINDER AND THAT THE FAILURE MOST LIKELY WAS DUE TO POOR BUILD QUALITY. *TR

AT 15,500 MILES, MY 2008 SUBARU STI EXPERIENCED A RINGLAND FAILURE ON THE #4 PISTON. THIS WAS VERIFIED VIA A COMPRESSION/LEAKDOWN TEST. A LONGBLOCK REPLACEMENT WAS APPROVED BY SUBARU OF AMERICA. MY MAIN CONCERN, WITHOUT TAKING ENGINE COMPONENTS OFF, THIS MILD CRACKED RINGLAND WAS ALMOST UN-DETECTABLE. THERE WAS VERY LITTLE DEGRADATION IN PERFORMANCE, FOR RUNNING ON 3.5 OF 4 CYLINDERS. IN ADDITION, MY MECHANIC ALSO FOUND FUEL IN THE OIL PAN. *TR

I OWN A 2008 STI AND HAVE JUST UNDER 6,000 MILES ON THE ODOMETER. I BOUGHT THE VEHICLE NEW WITH JUST UNDER 200 MILES ON IT IN DECEMBER OF 2008. IN JANUARY OF 2009, I BEGAN TO SEE WHITE SMOKE COMING OUT OF MY EXHAUST ON STARTUP. I HAD JUST OVER 1,200 MILES AT THE TIME. MY ENGINE FAILED SUFFERED A FAILURE AT JUST UNDER 2,000 MILES. SUBARU REPLACED THE ENGINE UNDER WARRANTY AND SENT ME ON MY WAY. FAST FORWARD TO JUNE OF 2009 AND NOW I'M BEING TOLD MY ENGINE HAS AGAIN FAILED DUE TO THE PISTON RINGLANDS CRACKING AND BREAKING OFF. THIS IS A WIDELY REPORTED ISSUE FROM 2008 STI OWNERS AND WOULD SEEM TO INDICATE A POSSIBLE DEFECT IN THE PISTON DESIGN. *TR
