2011 Porsche Cayenne S Problems

THE COOLANT PIPE DESIGN IS FLAWED. THE BARB IS GLUED AND PRESSED IN THE ALUMINUM BODY. OVER TIME THE GLUE LOSES ITS PROPERTIES AND THE BARB COMES OUT THUS CAUSING MASSIVE COOLANT LEAK AND THE ENGINE CAN OVERHEAT. THE PART WAS REDISGNED AROUND 2015 WHERE THE BARB IS NOW THREADED, BUT THE ORIGINAL PART IS A SAFEY HAZARD FOR THE OLDER MODELS WITH POTENTIAL HUGE REPAIR COSTS.

I WAS PULLING FORWARD ON A LEVEL CITY STREET AND TURNING LEFT FROM A STOP SIGN. THERE WAS A SIGNIFICANT AMOUNT OF SHUDDERING AND FEELING OF A LOSS OF POWER. THIS WAS A SIGNIFICANT SAFETY ISSUE DUE TO ONCOMING TRAFFIC. OVER A PERIOD OF SEVERAL MONTHS THIS HAD BEEN INCREASING IN SEVERITY BUT THE DEALER COULD NOT IDENTIFY THE PROBLEM. I TOOK IT TO THE DEALER AND WAS ABLE TO REPEAT THE PROBLEM FOR THEM. THEY IDENTIFIED THE TRANSFER CASE AS THE ISSUE. IT WAS REPLACED. I ALSO HAD TO REPLACE THE TIRES DUE TO THE DEALERS IDENTIFICATION THAT THE TRANSFER CASE HAD CAUSED DIFFERENTIAL TREAD WEAR DAMAGE TO A REAR TIRE. AS A FORMER MILITARY AVIATOR, THERE IS NO DOUBT IN MY MIND THAT THIS IS A SAFETY ISSUE. PORSCHE NEEDS TO IDENTIFY WHAT THE ISSUES ARE (DESIGN, MANUFACTURING, SERVICING, ETC) AND REMEDY THEM. SURPRISINGLY, THIS IS A KNOWN PROBLEM BECAUSE THE SERVICE ADVISER INFORMED ME THAT THEY KEEP TRANSFER CASES IN STOCK. THEY RETAIL FOR $3944, PLUS THE NEW VENT KIT (MINE DOES NOT HAVE IT) AND THEN ADD LABOR, AND TIRES IF THEY HAVE BEEN DAMAGED. THAT IS A LOT OF EXPENSIVE INVENTORY TO HAVE ON HAND IF PORSCHE WANTS TO CLAIM THERE IS NOT A PROBLEM.

VEHICLE ACTS AS IF GOING OVER SPEED BUMP OVER 18MPH ALSO JERKING AND TUGGING ON YOU AS YOU ACCELERATE MAKING FOR HARD TURNING IN PARKING LOTS FEELS LIKE FRONT WHEEL IS LOCKING UP ALSO NOTICING SAFETY CONCERN WILE COMING TO STOP IN TRAFFIC UNDER ABOUT 3MPH THE VEHICLE SUDDENLY AND UNEXPECTEDLY LEARCHES FORWARD AS IF ENGINE HAS MORE POWER OR SOMETHING BECOMES UN JAMMED. TRANSFER CASE HAS BEEN REPLACED ONCE ALREADY NOW OUT OF WARRANTY IT FEELS AS IF A SAFETY CONCERN IS THE ISSUE

TRANSFER CASE FAILED 2016 ; WAS REPLACED BY DEALER AND FAILED AGAIN 2017. WHILE DRIVING FAILURE AFFECTS SHIFTING AND ACCELERATION.

I CAME TO A COMPLETE STOP ON A CITY STREET. I LET MY FOOT OFF THE BRAKE, THEN APPLIED MY FOOT BACK ON THE BRAKE AND THE BRAKE PAD WOULDN'T GO DOWN, IT WAS HARD.

VERY SCARY AND DANGEROUS EXPERIENCE ENGINE STALLED AFTER FILLING UP WITH GAS. THE VEHICLE REQUIRED TWO OR THREE ATTEMPTS TO START. I EXITED THE GAS STATION ONTO THE RAMP FOR THE INTERSTATE. THE CAR SUDDENLY LOCKED UP LESS THAN A MILE DOWN THE INTERSTATE WHILE DRIVING 70, MPH. THERE WAS NO POWER BRAKING OR POWER STEERING AT ALL. FORTUNATELY, I REMAINED IN THE FAR RIGHT LANE AND MOMENTUM CARRIED THE VEHICLE OFF THE NEXT EXIT RAMP BEFORE VEHICLE COMPLETELY SHUT OFF. I HAVE HAD A HOST OF OTHER ISSUES INCLUDING PSM FAILURES, START/STOP MODE DEACTIVATED ERRORS, IGNITION PROBLEMS, BRAKING ISSUES, UNNECESSARY REPAIRS, TIME/ENERGY, MISSED WORK, RENTAL CARS, MISDIAGNOSES, ETC. I AM CERTAIN THE SYMPTOMS ARE CONSISTENT WITH CAMSHAFT DEFECT AFFECTING MANY OTHER CAYENNE S, TURBO, AND PANAMERA S OWNERS PER SEVERAL INTERNET FORUM DISCUSSIONS. THIS IS REALLY DANGEROUS. I AM DISAPPOINTMENT EARLIER NOTIFICATIONS WERE NOT ISSUED AND I HOPE THIS MATTER IS ADDRESSED BEFORE SOMEONE DIES.
