I WAS DRIVING MY VEHICLE DOWN THE HIGHWAY WHILE ACCELERATING WHEN I FELT THE CAR SQUIRM AND NOTICED A LARGE CLOUD OF SMOKE BILLOWING FROM THE REAR OF THE VEHICLE. I PULLED OVER AND IDENTIFIED THE ISSUE AS A CATASTROPHIC COOLANT LEAK FROM THE ENGINE AREA (REAR) OF THE VEHICLE. I HAD THE VEHICLE TRANSPORTED HOME AND THEN TO A REPAIR SHOP WHERE THEY IDENTIFIED THE PROBLEM AS A COOLANT LINE THAT BECAME SEPARATED FROM THE ENGINE BLOCK. IT WAS EXPLAINED TO ME THAT PORSCHE, FROM THE FACTORY, USED AN ADHESIVE LIKE MATERIAL TO MATE THE CONNECTORS OF THE COOLANT LINES AND ENGINE AND AFTER USAGE THEY WILL COME APART CAUSING COOLANT TO BE HEMORRHAGED ONTO THE ENGINE AND POTENTIALLY WHEELS/TIRES CAUSING FOR VERY DANGEROUS ROAD CONDITIONS. DURING THE INCIDENT I ALMOST LOST CONTROL OF MY VEHICLE DUE TO THE COOLANT CONTACTING THE TIRES WHICH WOULD NOT HAVE OTHERWISE HAPPENED HAD PORSCHE NOT MANUFACTURED THEIR VEHICLES IN THE AFOREMENTIONED WAY. I AS WELL AS OTHERS ON THE ROAD WERE PUT IN A VERY DANGEROUS SITUATION BECAUSE OF THIS MANUFACTURING ISSUE. *TR

Jun 16, 2003

CERTAIN PASSENGER VEHICLES MAY HAVE A LOOSE FITTING IN THE PRESSURE LINE OF THE POWER STEERING ASSEMBLY.

Consequence & remedy

Consequence: IF THE FITTING IS LOOSE, THE HYDRAULIC FLUID COULD LEAK OUT, WHICH COULD LEAD TO LOSS OF POWER STEERING ASSIST AND, FOR VEHICLES EQUIPPED WITH A MANUAL TRANSMISSION, LOSS OF CLUTCH ASSISTANCE. IF THE LEAKING FLUID COMES INTO CONTACT WITH HOT EXHAUST COMPONENTS, IT COULD IGNITE.

Remedy: DEALERS WILL TIGHTEN THE FITTING TO SPECIFICATIONS. OWNER NOTIFICATION BEGAN ON DECEMBER 1, 2003. OWNERS SHOULD CONTACT PORSCHE AT 1-800-545-8039.

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.
