Rapid coolant lossOpened April 26, 2013, closed March 10, 2014

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 the federal safety agency 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.

I had to pay thousands of dollars to have the coolant lines secured into the engine of my car. This car has a known fault in where the coolant lines come unsecured from the vehicle, dumping all coolant within seconds. Not only does this overheat the engine, but slippery coolant all over the rear tires of a vehicle means a crash can occur.

"permanent" coolant hose attachment failed; it came loose from its mounting in the engine resulting in coolant sprayed onto tire, with complete loss of control during a turn , including 270 degree spin, and leaving roadway; fortunately no other vehicles were nearby, so a collision was avoided. Apparently, this is not an unusual failure with the gt3 engine. Note: this was not a coolant hose or hose clamp failure, this was a structural failure of a permanent engine component to which the coolant hose mounts. Given the serious safety issues at stake, both to the driver of the vehicle and those also using the roadway near the affected vehicle, it should, in my opinion, be addressed with a safety recall as soon as possible. This is a design defect that is undetectable until the part fails, with potential loss of life and substantial property damage.

Coolant hose coupling came lose while driving the vehicle at speed, resulting in loss of all engine coolant. Coolant spilled resulted in temporary reduction of vehicle traction, fortunately without incident. Engine damage due to possible overheating is under investigation.

Sudden coolant line fitting failure. The epoxy failed and a coolant fitting completely popped out of the engine housing near the alternator. Resulted in rapid coolant loss. Car had to be towed/hauled approx 140 miles to repair facility near my home. I have not yet seen the bill for this service. I am having all coolant fittings welded to prevent this from happening to any of the other lines. Work is not yet complete but the estimated bill is $3500+.

I was driving my car on I-79(3 lane highway) at 70 MPH when I noticed a large cloud of smoke/steam from the rear of my car. I then noticed other cars pulling off to the side to get away from all the coolant spraying from my car. I pulled off to the side of the road and called for a tow truck. Ounce I was able to get porsche dealer to look at the issue, it was indicated that my coolant fittings failed and separated from the engine(know issue).

Engine coolant leaking at upper coolant console. Epoxy failed at aluminum cooling hose and cooling console connection point. At a later date, repeated failure of cooling hose connections at right front radiator.

I am reporting the issue of coolant line fitting failure. I have not had a failure yet but that my mechanic has advised me that this issue must be addressed and repaired before there is a catastrophic failure. This is a known and expensive issue so rather than waiting for a failure, I was advised by a mechanic that it is going to fail and needs to be repaired immediately.

Had coolant fittings welded to avoid catastrophic failure. Done in seattle; cost 3485 plus 250 sharkwerks fittings = 3735 total.

Due to a number of reported failures of the engine coolant lines on these vehicles (see http://forums.rennlist.com/rennforums/997-gt2-gt3-forum/592328-catastrophic-coolant-hose-coupling-failure-registry.html for reference), I had a preventative procedure performed where the coolant lines were welded into place. It seems that the adhesive which holds the lines in the engine fails and allows the lines to break away from the engine, causing a large coolant loss and potentially an accident. I have had a local shop repair this issue by welding the lines into place on the engine.
