Consumer Description

DRIVING DOWN THE INTERSTATE I HEARD AND FELT A FAINT PUDDERING. I LOOKED DOWN AND MY OIL LIGHT WAS ON. I WAS ABLE TO IMMEDIATELY EXIT. AS I WAS GOING ON THE OFF RAMP THE CHECK ENGINE LIGHT CAME ON. I WAS ABLE TO BARELY PULL INTO A PARK AND RIDE. 20 MINUTES LATER OIL WAS EVERYWHERE. THE CAR NEVER OVERHEATED, AND THERE WAS A TRAIL OF OIL FROM THE ROAD TO MY CAR. SINCE I HAD TAKEN IT TO THE GET THE OIL CHANGED JUST ON THE 5TH OF MAY, JUST 10 DAYS EARLIER. I HAD THE CAR TOWED TO THAT FACILITY. THE PISTON INTERNALLY SLAMMED THROUGH THE ENGINE PUNCHING A HOLE IN THE ENGINE WALL, AND LEAKING OIL FROM THE ENGINE. THE ENGINE DID NOT CEASE. PIECES AND PARTS OF BOLTS AND SIDE WALL WERE FOUND BY THE MECHANIC.
