DISCOVERED NUMEROUS PORSCHE CARS WITH GT1 BLOCK ENGINE PRE 2010 THAT ARE WATER COOLED HAVE COOLANT FITTINGS THAT ARE KNOWN TO FAIL DUE TO A GLUE THAT IS NOT HOLDING UP. AS SUCH, DRIVING CAN SUDDENLY RELEASE COOLANT ON THE GROUND CAUSING THE CAR AND THOSE CARS FOLLOWING IT TO CRASH WITHOUT ANY WARNING. THIS AFFECTS 996 AND 997 TURBOS AND GT3 VARIANTS. THE TOPIC IS DESCRIBED ON RENNLIST.COM, RENNTRACK.COM, AND A VENDOR ACTUALLY ADVERTISES A FIX (SHARKWERKS.COM). ONE GROUP OF PORSCHE DRIVING CLUB USERS WILL NOT LET CARS WITHOUT THIS BEING MITIGATED TO PARTICIPATE IN GROUP EVENTS DUE TO SAFETY CONCERNS BASED ON A BIG CRASH IN 2012 AT THE MIDOHIO TRACK (MAY BE 2011). NON TRACK, STREET CRASHES AND INCIDENTS ARE DOCUMENTS ON THE INTERNET. THIS GROUP OF CARS IS A HUGE RISK TO ALL OTHERS ON THE ROAD IN ADDITION TO THEMSELVES. SOMEONE IS GOING TO GET KILLED AND IT SEEMS TO BE ACCELERATING IN FREQUENCY. A REGISTRY OF CARS WITH THE PROBLEM AND INFORMATION CAN BE FOUND VIA THIS LINK: HTTP://FORUMS.RENNLIST.COM/RENNFORUMS/SHOWTHREAD.PHP?T=592328&REFERRERID=40465. *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.
