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.

THE VEHICLE LOST MOST OF IT'S POWER FROM AN ENGINE FAILURE WHILE TRAVELING AT APPROXIMATELY 60 MPH ON THE INTERSTATE ALMOST CAUSING ME TO BE REAR-ENDED AND A MULTI-CAR PILEUP. I WAS VERY FORTUNATE TO ESCAPE A MAJOR ACCIDENT. AN INDEPENDENT PORSCHE REPAIR SHOP, EURASIAN AUTO, "BORE SCORING" ON CYLINDER 5. FACTORY DEALER, PORSCHE OF BIRMINGHAM, CONFIRMED THAT DIAGNOSIS. THE AUTOMOBILE ONLY HAS 30,000 MILES ON IT. THE ENGINE NOW NEEDS TO BE COMPLETELY REBUILT. I SEARCHED ONLINE AND FOUND NUMEROUS EXAMPLES OF THIS SAME THING HAPPENING HAPPENING TO OTHER OWNERS OF 911S WITH THIS MODEL ENGINE. IT WAS USED IN 911S BETWEEN 05 AND 09. IT OCCURS IN BOTH THE 3,6 LITER ENGINE AND THE HIGHER HORSE POWER 3.8. SOME REPORTS SAY THE FAILURE IS EVEN MORE PREVALENT IN THE 3.8 LITER WHICH IS IN THE S VERSION. MY CAR IS A 3.8 LITER S VERSION. THE PROBLEM IS SO PREVALENT THAT SEVERAL COMPANIES NOW SPECIALIZE IN REMANUFACTURING 05 TO 09 911 ENGINES THAT HAVE SUFFERED BORE SCORING AND PROVIDING "FIXES" SO THAT BORE SCORING WILL NOT HAPPEN AGAIN. THESE COMPANIES INCLUDE FLAT SIX INNOVATIONS, RND, AND STRUTTCARS. IF YOU LOOK AT ANY OF THESE COMPANIES WEBSITES YOU WILL SEE AN EXPLANATION OF THE PROBLEM AND THEIR SOLUTIONS. PORSCHE IS AWARE OF THE PROBLEM AND HAS REFUSED TO ADDRESS THE ISSUE. SO THAT YOU WILL KNOW THIS SAFETY ISSUE IS NOT AN ISOLATED ISSUE, I ENCLOSE SEVERAL ONLINE REFERENCES TO THE PROBLEM. ALSO I WILL KEEP THE CAR GARAGED IN IT'S CURRENT CONDITION FOR 5 MONTHS IF YOU WANT TO TEST IT.

PURCHASED VEHICLE FROM PORSCHE DEALER ON JAN 2 2017 AND OPERATED IT 1600 MILES BEFORE IT BLEW A COOLANT FITTING AND EXPELLED COOLANT ALL OVER THE ROAD , REAR TIRE, AND REAR OF CAR. I WAS ON A BUSY INTERSTATE ON RAMP AND HEARD THE BELTS SQUEAL AND SAW STEAM IN THE REAR VIEW MIRROR. I COULD HAVE VERY EASILY LOST TRACTION IF THERE WERE NO CARS AHEAD OF ME GOING SLOW. LUCKILY WAS ABLE TO PULL OVER IMMEDIATELY AND TURN THE CAR OFF BEFORE CAUSING ENGINE DAMAGE. NO ONE BEHIND ME LOST TRACTION IN THE SLICK COOLANT FORTUNATELY . EXTREMELY DANGEROUS CONDITION THAT COULD EASILY CAUSE A SERIOUS ACCIDENT. HAD VEHICLE TOWED TO SELLING DEALER 3 DAYS OUT OF WARRANTY AND RECEIVED AN ESTIMATE OF $5200 TO REPAIR A COOLANT HOSE. OFFERED A 15% DISCOUNT, THEN AN ADDITIONAL $1000 OFF. I RESEARCHED THE COMMON COOLANT FITTING ISSUE WHERE THE EPOXIED FITTING COMES LOOSE OR ONE OF THE PLASTIC FITTINGS BREAK. THE SERVICE MANAGER ACTED LIKE HE HAD NEVER HEARD OF THAT AND SAID THEY WOULD REPLACE THE ONE HOSE . DECLINED REPAIR AND HAD VEHICLE TOWED TO INDEPENDENT SHOP WHERE IT WAS DISCOVERED THAT IT WAS A FITTING , NOT A HOSE AS THE SERVICE ADVISOR HAD STATED. ONE OTHER FITTING WAS ABOUT TO FAIL AS WELL. THIS LARGE WELL KNOWN SHOP PERFORMS UPGRADES TO THESE FITTINGS BY WELDING THEM SO THEY WON'T LET GO. $5000 TO FIX ALL SEVEN FITTINGS. WELD 5 ALUMINUM FITTINGS AND REPLACE THE 2 PLASTIC ONES WITH ALUMINUM AND WELD THEM ALSO. DEFINITELY A DESIGN FLAW THAT COULD PUT A DRIVER AND OTHERS IN A BAD SITUATION. BEEN WITHOUT THE CAR FOR OVER 3 WEEKS SO FAR .

MAJOR COOLANT LEAK ON TOP OF ENGINE ..ENGINE MUST COME OUT $6000 EST AT PORSCHE DEALER. COMMON PROBLEM I TOLD..PORSCHE SHOULD RECALL THIS ISSUE!!

Feb 05, 2017

I PURCHASED THIS VEHICLE LISTED ABOVE 2007 PORSCHE 911 TURBO ON MONDAY SEPTEMBER 15TH 2014 FROM CARLSTADT NEW JERSEY. I BEGAN TO DRIVE THE VEHICLE BACK TO WHERE I CURRENTLY LIVE IN SUMMERVILLE, SC. APPROXIMATELY 30 MINUTES INTO THE DRIVE A LIGHT CAME ON IN THE GAUGE WHICH SAID COOLANT FAILURE. I IMMEDIATELY PULLED THE VEHICLE OVER AND TURN THE CAR OFF. I OPENED THE REAR HATCH WHERE THE ENGINE IS HOUSED TO REVEAL STEAM POURING FROM THE BACK OF THE CAR. I CALLED AAA TO HAVE THE CAR TOWED TO THE NEAREST PORSCHE DEALERSHIP OFF THE NEW JERSEY INTERSTATE WHICH HAPPENED TO BE RAY CATENA PORSCHE OF EDISON NEW JERSEY. THE DEALERSHIP HAS VERIFIED THAT INDEED IT WAS A COOLANT FAILURE WHICH HAPPENS ON MODELS WITH GT1 ENGINE BLOCKS INCLUDING MY VEHICLE ABOVE. THE COOLANT FAILURE RESULTING IN ME ALMOST LOSING CONTROL OF THE VEHICLE AND COLLIDING WITH ANOTHER VEHICLE. PORSCHE OF NORTH AMERICA IS REFUSING TO ACKNOWLEDGE THIS AS AN ISSUE ON THESE VEHICLES WHICH IS WHY I'M FILING A COMPLIANT. MY VEHICLE IS PRESENTLY STILL BEING DIAGNOSE FURTHER BY THE DEALER TO SEE IF ANY ADDITIONAL DAMAGE HAS BEEN DONE TO THE MOTOR, WHICH HAS LEFT ME WITHOUT MY VEHICLE FOR OVER THREE WEEKS.

MY CAR BEGAN LEAKING COOLANT. AFTER TOWING MY CAR TO THE REPAIR SHOP I WAS TOLD MY METAL COOLANT FITTINGS ARE HELD IN WITH EPOXY AND ONE OF THEM HAD FAILED. TO REPAIR THIS IS A $6000.00 JOB. AFTER CALLING THE DEALER I FOUND OUT THIS IS A FAIRLY COMMON PROBLEM BUT THAT PORSCHE IS UNWILLING TO DO ANYTHING TO HELP THE CAR OWNERS PAY FOR IT AT THIS TIME. I THINK ANY TIME YOU HAVE A COMMON PROBLEM THAT IS THAT EXPENSIVE TO FIX YOU SHOULD AT HELP A LITTLE WITH THAT PROBLEM. *TR

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

May 02, 2013

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. *KB

VEHICLE HAD COMPLETE LOSS OF CONTROL DUE TO A COOLING SYSTEM FITTING COMING UNGLUED FROM THE ENGINE BLOCK. THE COOLANT FITTING IS PRESS FITTED INTO PLACE USING AN ADHESIVE THAT FAILED. THE ENTIRE CONTENTS OF THE COOLING SYSTEM RELEASED ONTO THE REAR TIRES CAUSING A LOSS OF CONTROL. *TR

Feb 10, 2011

COOLANT FITTING ADHESIVE FAILED, SPRAYING COOLANT ON REAR TIRES, WHICH CAUSED THE VEHICLE TO LOSE CONTROL. FITTING WAS REPLACED UNDER WARRANTY WITH THE SAME PROBLEMATIC ADHESIVE. MULTIPLE FAILURES HAVE BEEN NOTED IN PORSCHE FORUMS AND A RECENTLY PUBLISHED ARTICLE IN A GLOBAL MAGAZINE NOTED THIS ISSUE HAS BEEN AROUND FOR SEVERAL YEARS WITH THIS ENGINE TYPE, WITH NO RESOLUTION FROM PORSCHE. *LN

WAS LEAVING FREEWAY AND WENT TO HIT THE BRAKES AND HAD NO TRACTION. HAD SMELLED A LIQUID, WHICH IN RETROSPECT SEEMS TO HAVE BEEN COOLANT. MISSED HITTING OTHER VEHICLES, BUT THE CAR WAS IN A SINGLE CAR ACCIDENT - VEHICLE DAMAGE WAS EXCESSIVE AND THE CAR IS NOT REPAIRABLE. I WAS SERIOUSLY INJURED WITH MULTIPLE BROKEN BONES, FACIAL LACERATIONS, BRUISES, ETC. ORIGINALLY THOUGHT THAT THE BRAKES HAD FAILED, BUT LOSS OF TRACTION WOULD DUPLICATE THE EVENT - BASICALLY SMELLED COOLANT.

"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. *TR

CAUSE OF PROBLEM IS DUE TO CLUTCH MASTER SLAVE CYLINDER INTERNAL LEAK. PREMATURE FAILURE OF SLAVE CYLINDER. CLUTCH PADDLE WAS DEPRESS AND WILL NOT RETURN FULLY. FEW DAYS LATER, CLUTCH PADDLE WOULD STAY PUT ON THE FLOOR OF THE CAR. CHECK OUT THE BLOG AND IT IS A VERY COMMON PREMATURE FAILURE FOR THIS TYPICAL MODEL HOWEVER, PORSCHE DIDN'T SELL ENOUGH FOR EVERYONE TO GET ON BOARD WITH THE COMPLAINT. *TR

I NOTICED A SMALL POOL OF COOLANT UNDERNEATH THE ENGINE COMPARTMENT. UPON FURTHER RESEARCH I BELIEVE THE CAR IS SUFFERING FROM A COMMON PROBLEM OF THE COOLING FIXTURES THAT ARE GLUED ONTO THE MOTOR RATHER THAN WELDED. AMAZING THAT A CAR THIS EXPENSIVE WOULD HAVE SUCH A POORLY THOUGHT OUT PROBLEM LIKE THIS. I WILL TAKE THE CAR TO THE DEALER FOR ESTIMATES BUT I UNDERSTAND THAT AN ENGINE REMOVAL IS REQUIRED AND ALL COOLANT FIXTURES NEED TO BE WELDED. THIS IS A RATHER EXPENSIVE REPAIR FOR WHAT APPEARS TO BE A VERY FLAWED DESIGN. I HAVE DRIVEN THE CAR ONLY A FEW TIMES SINCE THE FIRST INCIDENT AND NOTICE A POOL OF COOLANT EVERY TIME THE CAR IS PARKED. I WILL NOT DRIVE THE CAR UNTIL FIXED AS I UNDERSTAND THE COOLANT LEAK CAN BE A HAZARD TO BE ME WHILE DRIVING AS WELL AS THE CARS BEHIND ME IF I SUFFER A CATASTROPHIC COOLANT LOSS. *TR

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. *TR

I AM CONCERNED THAT THIS COOLANT HOSE ISSUE WILL EFFECT MY CAR AND CAUSE A SAFETY HAZARD. I FEEL THAT THERE SHOULD BE A RECALL FROM PORSCHE TO FIX THIS. I UNDERSTAND THAT THE ENGINE COOLANT HOSE IS GLUED ON USING EPOXY INSTEAD OF WELDED OR THREADED. ALSO, I DON'T WANT TO HAVE TO SHELL OUT $3.5K TO FIX THIS SHOULD IT FAIL BECAUSE MY WARRANTY HAS EXPIRED. IF THE ACTUAL ENGINE BLOWS AS A RESULT OF THIS FAILURE I AM LOOKING AT WELL OVER $35000 TO REPLACE THE ENGINE AND FIX THE PROBLEM. MY ENGINE COOLANT TEMPERATURE SENSOR HAS ALREADY FAILED AND WAS REPLACED ON 08/17/2012. *TR

ON 06/09/12 (W/ APPROX 47K MILES) THE CAR BEGAN LEAKING COOLANT WHILE TRAVELING ON THE HIGHWAY. THE RATE OF THIS LEAK WAS SLOW AND WOULD HAVE TAKEN SEVERAL HOURS TO COMPLETELY DRAIN THE COOLANT FROM THE VEHICLE. THE CAR WAS STILL UNDER WARRANTY AT THE TIME OF THIS ISSUE. ON 03/29/13 ( W/ APPROX 54K MILES) MY PREGNANT WIFE AND I WERE A FEW MILES FROM ENTERING THE HIGHWAY WHEN THE CAR BEGIN TO LEAK COOLANT VERY RAPIDLY. ANOTHER MOTORIST FLAGGED ME DOWN AND ALERTED ME TO THE ISSUE ALMOST IMMEDIATELY AFTER IT HAPPENED. I PULLED OVER TO FIND A LARGE PUDDLE OF COOLANT UNDERNEATH THE CAR. ALSO, PLEASE NOTE THAT THE COOLANT DID APPEAR TO GET ON THE PASSENGER SIDE REAR TIRE. I CONSIDER MYSELF EXTREMELY LUCKY THAT THIS INCIDENT OCCURRED JUST BEFORE GETTING ON THE HIGHWAY AND NOT ON THE HIGHWAY. SOMEONE COULD HAVE BEEN SERIOUSLY INJURED HAD THIS COOLANT LEAK OCCURRED A FEW MINUTES LATER. THE CAR WAS NOT UNDER WARRANTY AT THE TIME OF THIS ISSUE. AFTER EXPERIENCING THIS SECOND COOLANT FAILURE I BEGAN TO DO RESEARCH AND DISCOVERED THAT MANY OTHER OWNERS HAD REPORTED SIMILAR PROBLEMS. *TR

THE PROBLEM WITH MY 2007 PORSCHE TURBO IS THAT WHEN I GO TO FILL UP GAS THE TANK WILL NOT FILL PASS 2/3 OF THE TANK. THE PROBLEM HAPPENS MOST OF THE TIMES THAT I FILL UP GAS AND PORSCHE HAS TOLD ME THAT THERE IS NO FIX TO THE PROBLEM. I AM SURE THAT IT IS NOT ONLY MY CAR THAT HAS THIS PROBLEM AS I HAVE SEARCHED ON THE INTERNET AND HAVE FOUND OTHERS WITH SIMILAR ISSUES. OUT OF THE MANY TIMES I HAVE TAKEN THE VEHICLE IN FOR SERVICE ONE TIME THEY CHANGE THE GAS TANK AND RELATING PARTS BUT IT DID NOT FIX THE ISSUE. *TR

1 complaint

THIS IS NOT A COMPLAINT OF A VEHICLE I OWN BUT A COMPLAINT I BELIEVE TO BE SAFETY RELATED. SOME PORSCHE MODELS LIKE 911 AND BOXTER HAVE A SIDE MARKER LIGHT THAT IS LOCATED AT THE WHEEL OPENING. AT NIGHT THERE IS A BRIGHT WHITE LIGHT THAT SHINES BACK AT VEHICLES DRIVING BEHIND THE PORSCHE IN THE LANE NEXT TO THEM. THIS EITHER MAKES IT HARD FOR THE OTHER DRIVING TO SEE AS THIS LIGHT HAS A BLINDING EFFECT OR WILL GIVE THE DRIVER THE IMPRESSION THAT AN ON COMING CAR IS APPROACHING IN THEIR LANE. I BELIEVE THE FIX TO BE SIMPLE BUT THE CURRENT SITUATION IS UNSAFE. *TR
