NO INCIDENT OCCURRED. HOWEVER, BASED ON MY KNOWLEDGE OF THE FAILURE OF THE COOLANT FITTINGS IN MY CAR AND WANTING TO TAKE A PROACTIVE STANCE I ELECTED TO MOVE FORWARD WITH A REMEDY. WHILE AT THE DEALERSHIP ON ANOTHER MATTER, THE ENGINE HAD BEEN REMOVED ALLOWING LIMITED ACCESS TO A NUMBER OF THE COOLANT FITTINGS. SINCE THE DEALER DISAVOWED ANY KNOWLEDGE OF THE PROBLEM AND WAS THEREFORE UNWILLING TO HELP I TOOK IT UPON MYSELF TO MECHANICALLY FASTEN THOSE COOLANT FITTINGS WHICH I HAD ACCESS TO. MIND YOU ALL WHILE THE DEALER LOOKED ON. I PROVIDED ALL THE TOOLS , PARTS AND PIECES WHICH I NEEDED TO DRILL AND FASTEN THOSE I HAD ACCESS TO. OTHERS , I SIMPLY SAFETY WIRED THE HOSE CLAMPS HOPING IT WOULD PREVENT A FAILURE IN THE FUTURE. MANY FAILURES HAVE OCCURRED AT HIGH SPEED TRACK EVENTS RESULTING IN CATASTROPHIC VEHICULAR LOSES. TO MY KNOWLEDGE THERE HAS BEEN NO LOSS OF LIFE WHICH IS JUST BY THE GRACE OF GOD. THIS PROBLEM HAS BEEN IN EXISTENCE FOR SEVERAL YEARS AND COVERED MANY MODELS.IT WAS THE FOCUS OF A FEATURE ARTICLE IN EXCELLENCE MAGAZINE, A MAGAZINE AVAILABLE IN BOOK STORES AND PRIMARILY DEDICATED TO THE PORSCHE BRAND. THE PORSCHE FACTORY HAD TO BE AWARE OF THE PROBLEM, BUT LIKE MANY OTHER ISSUES ELECTED TO IGNORE IT. *TR

HELLO, I DO NOT HAVE AN INCIDENT YET. HOWEVER, I AM EXTREMELY CONCERN THAT THE COOLANT PIPE WILL COME APART WHILE DRIVING CAUSING MASSIVE COOLANT LEAK.

PE13009 · Rapid Coolant Loss
Opened Apr 26, 2013 · Closed Mar 10, 2014
Status: closed (inferred from source dates) · Engine And Engine Cooling; Engine And Engine Cooling:cooling System; Engine And Engine Cooling:cooling System:hoses/lines/piping/fittings
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.
