50,000 MILES. IN SHOP BECAUSE OF SECURITY SYSTEM MALFUNCTION AND AN OIL CHANGE. MECHANIC INFORMED ME THAT AN IMS BEARING IS THROWING OFF BRASS FLAKES WHICH I COULD SEE IN THE OIL FILTER. THIS PROBLEM WILL EVENTUALLY CAUSE THE ENGINE TO FAIL. EVIDENTLY IT CANNOT BE REPAIRED. THE ONLY SOLUTION IS TO PUT IN A NEW ENGINE. THE3 2001 PORSCHE IS KNOWN FOR THIS ENGINE PROBLEM AND SHOULD BE ADDRESSED BY THE PNA. ACCORDING TO MY MECHANIC THE ENGINE IS FLAWED IN ITS DESIGNED AND NEVER SHOULD HAVE BEEN ALLOWED IN THE FIRST PLACE. THERE SHOULD BE A RECALL FOR THIS CAR.

20120625EXTERIOR LIGHTING

MINE IS A COMPLAINT REGARDING THE NEARLY NEW STYLE PLASTIC HEADLIGHTS BEING USED ON ALL VEHICLES MADE SINCE 2000. YOU SEE THEM EVERYWHERE AS THEY CAN BE EASILY IDENTIFIED BY THEIR CLOUDINESS AFTER SEVERAL YEARS OF USE. THERE ARE MANY MAKERS OF DIY FIX IT SOLUTIONS THAT WILL "REPAIR" THESE LENS TO ABOUT 75 PERCENT OF NEW BUT WITHIN 3 - 4 MONTHS THEY AGAIN RETURN TO CLOUDY AND CONTINUE TO GET WORSE UNTIL THEY ARE NEARLY USELESS. MANY PEOPLE CONTINUE TO USE THEM SINCE THERE IS NO COST EFFECTIVE SOLUTION. MY 2001 PORSCHE WHICH IS ALWAYS GARAGED AND DRIVEN LESS THAN 7,500 MILES PER YEAR WAS NOT SAFE AND I HAVE HAD THEM BOTH PROFESSIONALLY REPAIRED. THEY ARE NOW CLOUDY AGAIN AND THE ONLY SOLUTION IS A COMPLETE REPLACEMENT OF BOTH HEADLIGHTS WHICH WILL COST $3200 FOR THE PAIR. THE SOLUTION IS SIMPLE: STOP MANUFACTURERS FROM MAKING THESE ONE PIECE HEADLIGHTS AND MAKE THEM OFFER REPLACEMENT LENS COVERS THAT CAN BE INSTALLED AT A REASONABLE COST. A FRONT END COLLUSION WILL BE EXPENSIVE FOR INSUR
