I WAS DRIVING AROUND A CORNER ABOUT 40 MPH WHEN THE CAR SUDDENLY SPUN AROUND. I THEN SAW STEAM COMING FROM THE ENGINE. UPON FURTHER INSPECTION THERE WAS COOLANT ON THE GROUND. ONE OF THE COOLANT FITTINGS HAD COME COMPLETELY LOOSE, AND ALL THE COOLANT HAD LEAKED OUT. THE ONLY REAL FIX IS TO WELD ALL THE COOLANT FITTINGS. THERE ARE 9 OF THEM AND THE ENGINE HAS TO BE REMOVED TO DO THE WELDING. IT COST ME $2500 TO FIX THIS DEFECT. THIS IS A SAFETY ISSUE AS I WAS LUCKY I DID NOT HIT ANY ONE OR ANY THING. JUST PURE LUCK. WHEN YOU DUMP LARGE QUANTITIES OF SLIPPERY COOLANT ON TO THE REAR TIRES IT IS JUST A MATTER OF TIME BEFORE SOMEONE IS KILLED. THIS PROBLEM IS SO PREVALENT THAT MOST RACE TRACKS WON'T ALLOW A 996 OR 997 GT3, GT2 OR TURBO ON THE TRACK UNTIL THE COOLANT LINES ARE FIXED.

I WAS DRIVING AT MILLER MOTORSPORTS IN TOOELE UTAH IN DRIVERS EDUCATION EVENT WHEN MY ENGINE TEMPERATURE GAUGE STARTED TO INCREASE FROM 180 DEGREES UP PAST 200 DEGREES. AS THE TEMPERATURE GAUGE WENT TO 250 DEGREES, A COOLANT FAILURE LIGHT CAME ON. I PULLED OFF THE TRACK AND SHUT DOWN THE CAR WITHIN 2 MINUTES OF THE FAILURE LIGHT AND I HAD TO BE TOWED OFF THE MILLER MOTORSPORTS TRACK. I HAD LOST ALL OF MY COOLANT FROM THE CAR. THE NEXT MORNING (SUNDAY) I TOOK A RENTAL CAR BACK TO MILLER MOTORSPORTS ALONG WITH 9 GALLONS OF DISTILLED WATER. I POURED 2 GALLONS OF DISTILLED WATER INTO THE CAR, AND THEN STARTED IT. ABOUT SEVEN MINUTES LATER, WATER STARTED SPURTING FROM AN ALUMINUM COOLANT LINE ATTACHMENT THAT HAD COME UNGLUED. THIS ALUMINUM ATTACHMENT WAS IN A PLACE ON THE TOP OF THE ENGINE THAT WAS READILY DETERMINABLE AS THE WATER WAS SHOOTING STRAIGHT UP FROM WHERE THE FITTING HAD COME UNGLUED AND SLIPPED OFF. I DO NOT CURRENTLY KNOW WHETHER I GOT THE CAR STOPPED IN TIME FOR THE ENGINE TO BE OK. I AM AFRAID TO DRIVE IT BEFORE I GET ALL OF THE ALUMINUM FITTINGS REGLUED OR WELDED. BECAUSE THIS HAPPENED ON THE TOP OF THE ENGINE, THE COOLANT DID NOT CREATE A SITUATION THAT WAS A SAFETY RISK TO ME, BUT IF IT HAD BEEN A DIFFERENT ALUMINUM COOLANT ATTACHMENT THAT LET LOOSE, I COULD HAVE CRASHED AT 115 MPH DUE TO COOLANT ON THE TIRES OR SOMEONE BEHIND ME COULD HAVE CRASHED. THE MILLER MOTORSPORT PERSONNEL SAID THEY NOTICED A PLUME OF STEAM AT THE END OF THE FRONT STRAIGHT. AT THE END OF THE FRONT STRAIGHT, I HAD SLOWED TO 115 MPH. I AM THE ORIGINAL PURCHASER OF THIS CAR AND DID NOT THINK I WAS AT RISK FOR THIS TYPE OF SAFETY ISSUE ON A CAR THAT IS NOT DRIVEN IN STOP AND GO TRAFFIC. IT ALSO ONLY HAS A LITTLE OVER 28,000 MILES. *LN UPDATED 1/8/2013 *JS

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.
