2007 Porsche 911 Turbo

On April 26, 2013, the Office of Defects Investigation (ODI) opened PE13-009 to investigate 10 complaints alleging incidents of sudden coolant loss while traveling on public roadways in certain model year (MY) 2001 through 2007 Porsche 911 vehicles.The complaints alleged that pipe ends joined by epoxy to certain cooling system components may fail suddenly and separate, resulting in large volumes of coolant leakage.The investigation was opened to assess evidence of a design or manufacturing defect in the coolant pipe fittings and any related safety consequences. In response to ODI?s Information Request letter, Porsche identified a manufacturing quality issue with the supplier?s application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008).ODI?s analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier.Most of the leak complaints reviewed by ODI did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked.There were no crashes or injuries reported to be related to the alleged defect in any of the subject vehicles.ODI identified two allegations that coolant leakage resulted in loss of control incidents, but neither involved vehicles affected by the assembly process quality issue.A third loss of control allegation involving a vehicle built during the period affected by the supplier process concern is not counted since ODI was unable to contact the owner to confirm the incident.See the full closing resume in the document file for PE13-009 for additional information about the subject cooling system and ODI?s analysis of field data related to the alleged defect. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances.

PURCHASED VEHICLE FROM PORSCHE DEALER ON JAN 2 2017 AND OPERATED IT 1600 MILES BEFORE IT BLEW A COOLANT FITTING AND EXPELLED COOLANT ALL OVER THE ROAD , REAR TIRE, AND REAR OF CAR. I WAS ON A BUSY INTERSTATE ON RAMP AND HEARD THE BELTS SQUEAL AND SAW STEAM IN THE REAR VIEW MIRROR. I COULD HAVE VERY EASILY LOST TRACTION IF THERE WERE NO CARS AHEAD OF ME GOING SLOW. LUCKILY WAS ABLE TO PULL OVER IMMEDIATELY AND TURN THE CAR OFF BEFORE CAUSING ENGINE DAMAGE. NO ONE BEHIND ME LOST TRACTION IN THE SLICK COOLANT FORTUNATELY . EXTREMELY DANGEROUS CONDITION THAT COULD EASILY CAUSE A SERIOUS ACCIDENT. HAD VEHICLE TOWED TO SELLING DEALER 3 DAYS OUT OF WARRANTY AND RECEIVED AN ESTIMATE OF $5200 TO REPAIR A COOLANT HOSE. OFFERED A 15% DISCOUNT, THEN AN ADDITIONAL $1000 OFF. I RESEARCHED THE COMMON COOLANT FITTING ISSUE WHERE THE EPOXIED FITTING COMES LOOSE OR ONE OF THE PLASTIC FITTINGS BREAK. THE SERVICE MANAGER ACTED LIKE HE HAD NEVER HEARD OF THAT AND SAID THEY WOULD REPLACE THE ONE HOSE . DECLINED REPAIR AND HAD VEHICLE TOWED TO INDEPENDENT SHOP WHERE IT WAS DISCOVERED THAT IT WAS A FITTING , NOT A HOSE AS THE SERVICE ADVISOR HAD STATED. ONE OTHER FITTING WAS ABOUT TO FAIL AS WELL. THIS LARGE WELL KNOWN SHOP PERFORMS UPGRADES TO THESE FITTINGS BY WELDING THEM SO THEY WON'T LET GO. $5000 TO FIX ALL SEVEN FITTINGS. WELD 5 ALUMINUM FITTINGS AND REPLACE THE 2 PLASTIC ONES WITH ALUMINUM AND WELD THEM ALSO. DEFINITELY A DESIGN FLAW THAT COULD PUT A DRIVER AND OTHERS IN A BAD SITUATION. BEEN WITHOUT THE CAR FOR OVER 3 WEEKS SO FAR .

I PURCHASED THIS VEHICLE LISTED ABOVE 2007 PORSCHE 911 TURBO ON MONDAY SEPTEMBER 15TH 2014 FROM CARLSTADT NEW JERSEY. I BEGAN TO DRIVE THE VEHICLE BACK TO WHERE I CURRENTLY LIVE IN SUMMERVILLE, SC. APPROXIMATELY 30 MINUTES INTO THE DRIVE A LIGHT CAME ON IN THE GAUGE WHICH SAID COOLANT FAILURE. I IMMEDIATELY PULLED THE VEHICLE OVER AND TURN THE CAR OFF. I OPENED THE REAR HATCH WHERE THE ENGINE IS HOUSED TO REVEAL STEAM POURING FROM THE BACK OF THE CAR. I CALLED AAA TO HAVE THE CAR TOWED TO THE NEAREST PORSCHE DEALERSHIP OFF THE NEW JERSEY INTERSTATE WHICH HAPPENED TO BE RAY CATENA PORSCHE OF EDISON NEW JERSEY. THE DEALERSHIP HAS VERIFIED THAT INDEED IT WAS A COOLANT FAILURE WHICH HAPPENS ON MODELS WITH GT1 ENGINE BLOCKS INCLUDING MY VEHICLE ABOVE. THE COOLANT FAILURE RESULTING IN ME ALMOST LOSING CONTROL OF THE VEHICLE AND COLLIDING WITH ANOTHER VEHICLE. PORSCHE OF NORTH AMERICA IS REFUSING TO ACKNOWLEDGE THIS AS AN ISSUE ON THESE VEHICLES WHICH IS WHY I'M FILING A COMPLIANT. MY VEHICLE IS PRESENTLY STILL BEING DIAGNOSE FURTHER BY THE DEALER TO SEE IF ANY ADDITIONAL DAMAGE HAS BEEN DONE TO THE MOTOR, WHICH HAS LEFT ME WITHOUT MY VEHICLE FOR OVER THREE WEEKS.

I NOTICED A SMALL COOLANT LEAK FROM THE REAR DRIVERS SIDE OF THE ENGINE. THIS LEAK BECAME MORE PROMINENT OVER THE NEXT SEVERAL DAYS. I TOOK MY CAR TO THE SHOP TO HAVE IT EVALUATED AND IT WAS DETERMINED THAT 4 OUT OF 6 COOLANT FITTINGS WERE LEAKING. THE DESIGN FROM PORSCHE HAS THE COOLANT HOSES AFFIXED USING AN EPOXY. AFTER MANY HEAT CYCLES AND TIME, THIS EPOXY FAILS AND COOLANT LEAKS FROM THE ENGINE. THE ENGINE MUST BE REMOVED TO PROPERLY FIX THE PROBLEM AND IT IS GOING TO COST ME APPROXIMATELY $6,000. THIS IS A KNOWN ISSUE FOR THIS CAR AND IS SOMETHING PORSCHE SHOULD TAKE CARE OF. *TR

ALL CONNECTION PIECES THAT CONNECT TO A RUBBER HOSE ARE LEAKING. THE PIPE THAT COMES OUT OF THE CASTING IS GLUED FROM THE FACTORY. AFTER TIME THE TUBE WILL MOVE AND WATER STARTS COMING OUT IN BETWEEN THE PIPE AND THE CASTING. YOU AN GO TO THIS WEB ADDRESS AND SE WHAT I'M RAKING ABOUT. THIS FROM WHAT I HAVE HEARD AND NOW MY ON CAR IS SOMETHING THAT HAPPENS TO ALL 2007 PORSCHE TURBO ENGINES. THE PROBLEM IS THAT THE CAR IS OUT OF WARRANTY AND PORSCHE DOESN'T WANT TO FIX IT UNDER WARRANTY. I'M GETTING IT FIXED NOW AND COST IS GOING TO BE OVER $2,000.00 DOLLARS. JUST LIKE THE IMS BEARING FAILURE ON PREVIOUS PORSCHE CARS IT'S GOING TO TAKE AWHILE BEFORE PORSCHE WANTS TO DO ANYTHING TO HELP ANYONE WITH THIS ISSUE. HTTP://WWW.YOUTUBE.COM/WATCH?V=WIL2-VBANVK THE ABOVE WEB-SITE WILL SHOW YOU ONE OF THE ISSUES. IT WILL NOT SHOW YOU THAT ALL PIPES ARE OR WILL COME LOOSE. I REALLY WOULD LIKE TO GET THIS COVERED UNDER WARRANTY. THANKS

CAUSE OF PROBLEM IS DUE TO CLUTCH MASTER SLAVE CYLINDER INTERNAL LEAK. PREMATURE FAILURE OF SLAVE CYLINDER. CLUTCH PADDLE WAS DEPRESS AND WILL NOT RETURN FULLY. FEW DAYS LATER, CLUTCH PADDLE WOULD STAY PUT ON THE FLOOR OF THE CAR. CHECK OUT THE BLOG AND IT IS A VERY COMMON PREMATURE FAILURE FOR THIS TYPICAL MODEL HOWEVER, PORSCHE DIDN'T SELL ENOUGH FOR EVERYONE TO GET ON BOARD WITH THE COMPLAINT. *TR

I NOTICED A SMALL POOL OF COOLANT UNDERNEATH THE ENGINE COMPARTMENT. UPON FURTHER RESEARCH I BELIEVE THE CAR IS SUFFERING FROM A COMMON PROBLEM OF THE COOLING FIXTURES THAT ARE GLUED ONTO THE MOTOR RATHER THAN WELDED. AMAZING THAT A CAR THIS EXPENSIVE WOULD HAVE SUCH A POORLY THOUGHT OUT PROBLEM LIKE THIS. I WILL TAKE THE CAR TO THE DEALER FOR ESTIMATES BUT I UNDERSTAND THAT AN ENGINE REMOVAL IS REQUIRED AND ALL COOLANT FIXTURES NEED TO BE WELDED. THIS IS A RATHER EXPENSIVE REPAIR FOR WHAT APPEARS TO BE A VERY FLAWED DESIGN. I HAVE DRIVEN THE CAR ONLY A FEW TIMES SINCE THE FIRST INCIDENT AND NOTICE A POOL OF COOLANT EVERY TIME THE CAR IS PARKED. I WILL NOT DRIVE THE CAR UNTIL FIXED AS I UNDERSTAND THE COOLANT LEAK CAN BE A HAZARD TO BE ME WHILE DRIVING AS WELL AS THE CARS BEHIND ME IF I SUFFER A CATASTROPHIC COOLANT LOSS. *TR
