THE VEHICLE LOST MOST OF IT'S POWER FROM AN ENGINE FAILURE WHILE TRAVELING AT APPROXIMATELY 60 MPH ON THE INTERSTATE ALMOST CAUSING ME TO BE REAR-ENDED AND A MULTI-CAR PILEUP. I WAS VERY FORTUNATE TO ESCAPE A MAJOR ACCIDENT. AN INDEPENDENT PORSCHE REPAIR SHOP, EURASIAN AUTO, "BORE SCORING" ON CYLINDER 5. FACTORY DEALER, PORSCHE OF BIRMINGHAM, CONFIRMED THAT DIAGNOSIS. THE AUTOMOBILE ONLY HAS 30,000 MILES ON IT. THE ENGINE NOW NEEDS TO BE COMPLETELY REBUILT. I SEARCHED ONLINE AND FOUND NUMEROUS EXAMPLES OF THIS SAME THING HAPPENING HAPPENING TO OTHER OWNERS OF 911S WITH THIS MODEL ENGINE. IT WAS USED IN 911S BETWEEN 05 AND 09. IT OCCURS IN BOTH THE 3,6 LITER ENGINE AND THE HIGHER HORSE POWER 3.8. SOME REPORTS SAY THE FAILURE IS EVEN MORE PREVALENT IN THE 3.8 LITER WHICH IS IN THE S VERSION. MY CAR IS A 3.8 LITER S VERSION. THE PROBLEM IS SO PREVALENT THAT SEVERAL COMPANIES NOW SPECIALIZE IN REMANUFACTURING 05 TO 09 911 ENGINES THAT HAVE SUFFERED BORE SCORING AND PROVIDING "FIXES" SO T

I AM SUBMITTING THIS DUE TO THE PROBLEMS ASSOCIATED WITH THE COOLANT LINES COMING OUT OF THE MOTOR BLOCK. THIS DID NOT HAPPEN TO MY CAR BUT I FELT THE RISK WAS TO HIGH CONSIDERING ALL OF THE DOCUMENTED FAILURES (HTTP://FORUMS.RENNLIST.COM/RENNFORUMS/997-GT2-GT3-FORUM/592328-CATASTROPHIC-COOLANT-HOSE-COUPLING-FAILURE-REGISTRY.HTML ). THIS SERIES OF CARS HAVE BEEN KNOWN TO DROP ALL OF THE COOLANT OUT WHILE DRIVING. I ELECTED TO HAVE THE COOLANT HOSES SECURED AT A COST OF $3100. I DID NOT WANT TO BE DRIVING AND CRASH OR CAUSE ANOTHER DRIVER BEHIND ME TO CRASH. *TR

20080406EXTERIOR LIGHTING
THIS IS NOT A COMPLAINT OF A VEHICLE I OWN BUT A COMPLAINT I BELIEVE TO BE SAFETY RELATED. SOME PORSCHE MODELS LIKE 911 AND BOXTER HAVE A SIDE MARKER LIGHT THAT IS LOCATED AT THE WHEEL OPENING. AT NIGHT THERE IS A BRIGHT WHITE LIGHT THAT SHINES BACK AT VEHICLES DRIVING BEHIND THE PORSCHE IN THE LANE NEXT TO THEM. THIS EITHER MAKES IT HARD FOR THE OTHER DRIVING TO SEE AS THIS LIGHT HAS A BLINDING EFFECT OR WILL GIVE THE DRIVER THE IMPRESSION THAT AN ON COMING CAR IS APPROACHING IN THEIR LANE. I BELIEVE THE FIX TO BE SIMPLE BUT THE CURRENT SITUATION IS UNSAFE. *TR
