I AM CONCERNED THAT THIS COOLANT HOSE ISSUE WILL EFFECT MY CAR AND CAUSE A SAFETY HAZARD. I FEEL THAT THERE SHOULD BE A RECALL FROM PORSCHE TO FIX THIS. I UNDERSTAND THAT THE ENGINE COOLANT HOSE IS GLUED ON USING EPOXY INSTEAD OF WELDED OR THREADED. ALSO, I DON'T WANT TO HAVE TO SHELL OUT $3.5K TO FIX THIS SHOULD IT FAIL BECAUSE MY WARRANTY HAS EXPIRED. IF THE ACTUAL ENGINE BLOWS AS A RESULT OF THIS FAILURE I AM LOOKING AT WELL OVER $35000 TO REPLACE THE ENGINE AND FIX THE PROBLEM. MY ENGINE COOLANT TEMPERATURE SENSOR HAS ALREADY FAILED AND WAS REPLACED ON 08/17/2012. *TR

COOLANT PIPE FAILURE. AFTER DRIVING BACK FROM THE AIRPORT AND PARKING, NOTICED HUGE COOLANT POOL FORM UNDER THE CAR. TOOK CAR TO SHOP AND THEY SCOPED THE COOLANT SYSTEM AND FOUND THE COOLANT PIPES HAVE STARTED TO SEPARATE. SHOP SAID THEY HAVE DONE MANY OF THESE REPAIRS, AND THAT MANY TRACKS WILL NOT LET 911 TURBOS ON THEM UNLESS THEY HAVE THESE WELDED BECAUSE OF THE HIGH NUMBER OF SEPARATIONS OF THESE PIPES. SEEMS LIKE THE EPOXY METHOD OF SECURING THESE IS NOT SUFFICIENT FOR THESE CARS. *TR

THEY TOLD ME THAT IT WOULD NOT BE SAFE TO DRIVE THE CAR WITHOUT REPLACING THE COOLANT HOSE FITTINGS SINCE IT WOULD SPRAY COOLANT ALL OVER MY TIRES AND THE ROAD. THEY SAID THAT COOLANT SPILLED ON THE ROAD WOULD MAKE IT VERY SLIPPERY AND COULD CAUSE CARS FOLLOWING ME TO CRASH. THE DEALER REPLACED ALL FITTINGS AND HOSES ON THE CAR. *TR

ON 06/09/12 (W/ APPROX 47K MILES) THE CAR BEGAN LEAKING COOLANT WHILE TRAVELING ON THE HIGHWAY. THE RATE OF THIS LEAK WAS SLOW AND WOULD HAVE TAKEN SEVERAL HOURS TO COMPLETELY DRAIN THE COOLANT FROM THE VEHICLE. THE CAR WAS STILL UNDER WARRANTY AT THE TIME OF THIS ISSUE. ON 03/29/13 ( W/ APPROX 54K MILES) MY PREGNANT WIFE AND I WERE A FEW MILES FROM ENTERING THE HIGHWAY WHEN THE CAR BEGIN TO LEAK COOLANT VERY RAPIDLY. ANOTHER MOTORIST FLAGGED ME DOWN AND ALERTED ME TO THE ISSUE ALMOST IMMEDIATELY AFTER IT HAPPENED. I PULLED OVER TO FIND A LARGE PUDDLE OF COOLANT UNDERNEATH THE CAR. ALSO, PLEASE NOTE THAT THE COOLANT DID APPEAR TO GET ON THE PASSENGER SIDE REAR TIRE. I CONSIDER MYSELF EXTREMELY LUCKY THAT THIS INCIDENT OCCURRED JUST BEFORE GETTING ON THE HIGHWAY AND NOT ON THE HIGHWAY. SOMEONE COULD HAVE BEEN SERIOUSLY INJURED HAD THIS COOLANT LEAK OCCURRED A FEW MINUTES LATER. THE CAR WAS NOT UNDER WARRANTY AT THE TIME OF THIS ISSUE. AFTER EXPERIENCING THIS SECOND COOLANT FAILURE I BEGAN TO DO RESEARCH AND DISCOVERED THAT MANY OTHER OWNERS HAD REPORTED SIMILAR PROBLEMS. *TR

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.
