COOLANT PIPE EXPERIENCED CATASTROPHIC FAILURE WHILE ON A PUBLIC ROADWAY. WAS TRAVELING ON STRAIGHT, SMOOTH ROAD ABOUT 55-60MPH WHEN COOLANT WARNING LIGHT CAME ON AND ENGINE TEMPERATURE ROSE WITHOUT WARNING. I HAD NO WHERE TO PULL OVER ON THE TWO-LANE ROAD, SO WAS FORCED TO STOP CAR IN LANE, PUTTING MYSELF AND FAMILY AT RISK OF BEING HIT BY TRAFFIC WHILE WE WAITED 4 HOURS FOR A TOW.

COOLANT PIPES COME APART WHILE DRIVING AND THERE WAS RAPID LOSS OF ENGINE COOLANT. THE PROBLEM EXISTS ON THE GT1 MOTOR BECAUSE THERE ARE A COUPLE COOLANT PIPES IN THESE MOTORS THAT ARE NOT A SINGLE CAST PIECE: THE LARGER CAST PIECES HAVE EXTRUDED INLET/OUTLET TUBES THAT ARE CONNECTED USING AN ADHESIVE. THERE IS NO METAL-TO-METAL FRICTION OR PRESS-FIT TO KEEP THESE TUBES IN PLACE, SO AFTER ENOUGH HEAT CYCLES THE ADHESIVE WILL SOFTEN/LOOSEN UP AND THE TUBE WILL COME OUT OF THE CAST BLOCK (WITH THE HOSE STILL ATTACHED), RESULTING IN A RAPID LOSS OF ENGINE COOLANT. ....UPDATED 04/25/16 *BF

WHILE DRIVING ON THE HIGHWAY A CATASTROPHIC FAILURE OCCURRED IN THE COOLANT SYSTEM. ONE OF THE ALUMINUM HOSE FITTINGS THAT IS EPOXIED INTO THE ALUMINUM HOUSING BROKE FREE CAUSING ENGINE COOLANT TO EMPTY OUT OF THE ENGINE ONTO THE HIGHWAY IN A MATTER OF SECONDS. THE RUBBER HOSE DID NOT FAIL AND IT WAS STILL CONNECTED TO ALUMINUM HOSE FITTING THAT BROKE AWAY FROM THE HOUSING. I PULLED THE CAR OFF THE FREEWAY IMMEDIATELY TO PREVENT FURTHER DAMAGE TO THE CAR. FURTHER INSPECTION AT THE DEALER SERVICE CENTER SHOWED THERE WAS VERY LITTLE TO NO COOLANT LEFT IN THE ENTIRE SYSTEM. *TR

I HAVE BEEN INFORMED BY MY PORSCHE TECHNICIAN THAT PORSCHE USED AN INFERIOR AND MECHANICALLY POOR DESIGN FOR THE ENGINE COOLANT LINES. THEY ARE GLUED TOGETHER IN A PLACE WHERE THEY GET HOT. AFTER SEVERAL HEAT CYCLES, THEY WILL FAIL. ALL CARS WITH THIS ENGINE DESIGN WILL HAVE THIS FAILURE OVER TIME. IF THE COOLANT LINES FAIL WHILE THE CAR IS MOVING, THE SLICK COOLANT CAN GET ON THE TIRES AND CAUSE AN ACCIDENT. ALSO, THE ENGINE CAN OVERHEAT WITH A REPLACEMENT COST OF OVER $20,000. PORSCHE IS AWARE OF THIS, AS THEY HAVE USED A SUPERIOR THREADED DESIGN ON THEIR RACE CARS WITH THIS ENGINE. I HAVE BEEN ADVISED THAT THIS WILL TAKE THOUSANDS OF DOLLARS TO FIX, AND THE CAR WILL BE OUT OF SERVICE FOR…

I WAS ACCELERATING UP TO HIGHWAY SPEEDS (65 MPH) ON A ON RAMP WHEN I HEARD A POP UNDER THE CAR. I FELT THE CAR SHAKE AND DECIDED TO PULL OVER. I DISCOVERED COOLANT LEAKING FROM UNDER THE CAR AND THE SHAKE WAS CAUSED BY MY REAR TIRES SLIPPING AND TRACTION CONTROL COMPENSATING FOR ACCELERATION UNDER SLIPPERY CONDITIONS. LUCKILY I DIDN'T LOOSE CONTROL AND CRASH INTO ANOTHER PERSON THAT MAY HAVE CAUSED INJURY OR DEATH TO THEM OR MYSELF. THE COOLANT PIPING IS A WELL KNOWN PROBLEM WITH THIS YEAR MODEL CAR, IT IS ONLY SECURED BY A GLUE LIKE SUBSTANCE NOT CLAMPED, IT SEEM THE GLUE LET GO AND CAUSED A PRESSURE RELEASE IN MY COOLANT SYSTEM. *TR
