2007 Porsche 911 GT3 problems

ENGINE

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.

STEERING

"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.

ENGINE

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+.

ENGINE

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

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.

ENGINE

HAD COOLANT FITTINGS WELDED TO AVOID CATASTROPHIC FAILURE. DONE IN SEATTLE; COST 3485 PLUS 250 SHARKWERKS FITTINGS = 3735 TOTAL.

ENGINE

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.

ENGINE

NO INCIDENT OCCURRED. HOWEVER, BASED ON MY KNOWLEDGE OF THE FAILURE OF THE COOLANT FITTINGS IN MY CAR AND WANTING TO TAKE A PROACTIVE STANCE I ELECTED TO MOVE FORWARD WITH A REMEDY. WHILE AT THE DEALERSHIP ON ANOTHER MATTER, THE ENGINE HAD BEEN REMOVED ALLOWING LIMITED ACCESS TO A NUMBER OF THE COOLANT FITTINGS. SINCE THE DEALER DISAVOWED ANY KNOWLEDGE OF THE PROBLEM AND WAS THEREFORE UNWILLING TO HELP I TOOK IT UPON MYSELF TO MECHANICALLY FASTEN THOSE COOLANT FITTINGS WHICH I HAD ACCESS TO. MIND YOU ALL WHILE THE DEALER LOOKED ON. I PROVIDED ALL THE TOOLS , PARTS AND PIECES WHICH I NEEDED TO DRILL AND FASTEN THOSE I HAD ACCESS TO. OTHERS , I SIMPLY SAFETY WIRED THE HOSE CLAMPS HOPING IT WOULD PREVENT A FAILURE IN THE FUTURE. MANY FAILURES HAVE OCCURRED AT HIGH SPEED TRACK EVENTS RESULTING IN CATASTROPHIC VEHICULAR LOSES. TO MY KNOWLEDGE THERE HAS BEEN NO LOSS OF LIFE WHICH IS JUST BY THE GRACE OF GOD. THIS PROBLEM HAS BEEN IN EXISTENCE FOR SEVERAL YEARS AND COVERED MANY MODELS.IT WAS THE FOCUS OF A FEATURE ARTICLE IN EXCELLENCE MAGAZINE, A MAGAZINE AVAILABLE IN BOOK STORES AND PRIMARILY DEDICATED TO THE PORSCHE BRAND. THE PORSCHE FACTORY HAD TO BE AWARE OF THE PROBLEM, BUT LIKE MANY OTHER ISSUES ELECTED TO IGNORE IT.

COOLING FITTING FAILURE ON PORSCHE 911 GT3 RS 2007 WITH GLUED IN FITTINGS.

NHTSA complaint #10510444 — an unverified report by a vehicle owner.

ENGINE

HELLO, I DO NOT HAVE AN INCIDENT YET. HOWEVER, I AM EXTREMELY CONCERN THAT THE COOLANT PIPE WILL COME APART WHILE DRIVING CAUSING MASSIVE COOLANT LEAK. THE SLIPPERY COOLANT CAN CAUSE SPINS AND CRASHES FOR ME AND OTHER DRIVERS AROUND ME. THANK YOU.

TL* THE CONTACT OWNS A 2007 PORSCHE 911 GT3. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO THE DEALER FOR ROUTINE MAINTENANCE WHEN THE MECHANIC ADVISED THAT THE HOSE FITTINGS FOR THE ENGINE COOLING SYSTEM WERE FAULTY AND WOULD EVENTUALLY FAIL. THE CONTACT WAS ADVISED TO HAVE THE HOSE FITTINGS REPLACED. THE VEHICLE WAS NOT REPAIRED HOWEVER, THE CONTACT STATED THAT THE MECHANIC WAS CONVINCED THAT THE COMPONENT WOULD FAIL. THE FAILURE MILEAGE WAS 9,000 AND THE CURRENT MILEAGE WAS 9,800. THE VIN WAS NOT AVAILABLE.

ENGINE

STARTING TO SEE WEEPING FROM A PRESSED AND GLUED COOLANT LINE AT THE ENGINE. IT WILL NEED TO BE ADDRESSED VERY SOON AS IT IS AN EXTREMELY DANGEROUS SITUATION IF IT FAILS WHILE DRIVING. COOLANT WILL POUR ONTO THE REAR TIRES AND CAUSE THE REAR END TO SLIDE. I CANNOT DRIVE THE CAR UNTIL THIS IS RESOLVED. VERY POOR MFG DECISION BY PORSCHE. THESE FITTINGS SHOULD HAVE BEEN THREADED, PINNED OR SECURED IN SOME OTHER MANNER. USING GLUE IS JUST RIDICULOUS.

ENGINE

COOLANT LEAK NOTICED AT COOLANT MANIFOLD FITTING DURING OIL CHANGE. ENGINE WAS WARMED UP PRIOR TO OIL DRAIN, THEREFORE WAS AT OPERATING TEMPERATURE. SEEPAGE AT FITTING INTO MANIFOLD WAS DETECTED BY SMELL AND THEN LOCATED WITH LIGHT AND MIRROR. I HAD TO HAVE THE ENGINE REMOVED AND THE FITTINGS WELDED BY MY LOCAL INDEPENDENT SHOP. ALL OF THE FITTINGS WERE GLUED INTO THE CASTINGS AND WERE PRONE TO FAILURE AT ANY TIME.

ENGINE

I DRIVE THIS CAR ON THE HIGHWAY AND ON THE TRACK APPROXIMATELY 5 WEEKENDS A YEAR. I HAVE SEEN MULTIPLE ENGINE COOLANT PIPE FAILURES ON THESE GT3'S AND I FEAR I WILL BE NEXT AND FEAR IT MAY CAUSE OTHER VEHICLES BEHIND ME TO CRASH. ITS NOT SAFE FOR THESE COOLANT LINES TO BREAK WHICH CAN OCCUR ON THE TRACK OR THE HIGHWAY. IT SEEMS TO BE A PORSCHE PROBLEM IN CLIMATES WITH LOTS OF VARIATIONS IN TEMPERATURE BOTH HOT AND COLD WITH THE EXPANDING OF THE HOSE AND/OR THE GLUE KEEPING THEM IN PLACE.

ENGINE

A COOLANT HOSE PRESS FITTING WHICH IS APPARENTLY GLUED INTO THE ENGINE BLOCK LOST ADHESION AND DISCONNECTED. THIS RESULTED IN A COMPLETE LOSS OF COOLANT AND A CORRESPONDING LOSS OF CONTROL DUE TO HOT, SLIPPERY COOLANT COATING THE REAR WHEELS OF THE CAR AND ROAD SURFACE. CAR SPUN AND LEFT THE ROAD BUT FORTUNATELY DID NOT HIT ANYTHING. COOLANT SPILL DID IMPACT OTHER MOTORISTS WHO SPUN OUT ON THE COOLANT BUT DID NOT CRASH. MY RESEARCH INDICATES THAT THIS IS A COMMON, SYSTEMIC PROBLEM WITH THIS MODEL ENGINE AND APPEARS TO BE A DANGEROUS DEFECT IN THE ENGINE CONSTRUCTION. I DID CONTACT PORSCHE TWICE BUT THERE HAS NOT BEEN A RESPONSE. I DID HAVE ALL THE COOLANT FITTINGS REMOVED, CLEANED AND WELDED IN. NO PROBLEM SINCE.

ENGINE

COOLANT FITTINGS WERE PINNED AFTER CAR STARTED TO SHOW A SMALL WEEPING LEAK ON ONE OF THE FITTINGS. MEZGER ENGINE 911'S SPLIT THE FITTINGS AND CAN CAUSE RAPID COOLANT LOSS AND A SUDDEN LOSS OF TRACTION.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

DRIVING A 2007 PORSCHE GT3 WHEN A HOSE FITTING CAME LOOSE FROM THE ENGINE BLOCK CAUSING A CATASTROPHIC LOSS OF COOLANT FROM THE ENGINE. THE FAILURE CAN OCCUR MULTIPLE TIMES I HAVE BEEN TOLD BY OTHER OWNERS OF 996 AND 997 MODEL PORSCHE 911 MODEL VARIANTS. OCCURS IN ALL MODELS (CARRERA, TURBO, GT3, GT3RS) AS NOTED HERE: HTTP://FORUMS.RENNLIST.COM/RENNFORUMS/SHOWTHREAD.PHP?T=592328&GOTO=NEWPOST. CONSEQUENCES ARE DUMPING OF ANTIFREEZE ON THE ROADWAY WHICH HAS A POTENTIAL TO CAUSE AN ACCIDENT. MY CAR WAS FIXED BY PORSCHE UNDER WARRANTY. PORSCHE REPLACED FITTINGS IN THE BLOCK WHICH WERE EPOXIED IN AS WERE THE ORIGINAL FITTINGS. A MORE PERMANENT SOLUTION SHOULD BE REQUIRED, SUCH AS WELDING OR PINNING OF THE FITTINGS INTO THE ENGINE CASE. OLD PARTS ARE NOT AVAILABLE AS PORSCHE WILL NOT TURN OVER ANY PARTS REPLACED UNDER WARRANTY.
