2012 PORSCHE CAYENNE Complaints

2012 PORSCHE CAYENNE WITH 47,000 MILES. NOTICED JERKING WHEN TURNING LEFT AND SOME SLIPPAGE IN TRANSMISSION. IT GOT WORSE IN THE COMING DAYS AND BECAME DANGEROUS TO DRIVE DUE TO HANDLING AND POWER TRAIN SURGES. I TOOK IT TO SOUTHPOINT PORSCHE IN DURHAM, NC, THIS WEEK AND WAS TOLD IT NEEDS A NEW $4,435 TRANSFER CASE. A LOCAL PORSCHE SHOP DIRECTED ME TO REVIEWS WHICH NOTE THE SAME 'KNOWN' ISSUE - DUE TO A KNOWN DEFECT THAT DRAINS FLUID BY TRANSFER CASE AND GETS MOISTURE INTO THE CASE. PORSCHE HAS ISSUED CORRECTIVE INSTRUCTIONS FOR REPAIRS BUT NO RECALL (KNOWN) OR CALLBACK TO REPAIR AT THEIR COST. TRANSMISSION CAN LOCK UP DURING DRIVING CAUSING SERIOUS INJURIES OR DEATH. I ASKED DEALERSHIP TO CONTACT PORSCHE AND REGIONAL REP AND TO SHARE MY CONCERNS AND LINKS TO FORUMS WHERE THIS ISSUE IS OUTLINED IN MANY OTHER PORSCHE CAYENNE CASES.

THE TRANSFER CASE IN THIS CAR IS FAILING AT 53,000 MILES CAUSING UNSAFE, JERKING ACCELERATION LEADING TO TOTAL BREAKDOWN/SHUTDOWN IF NOT CORRECTED. NUMEROUS OWNERS EXPERIENCE THE SAME ISSUE. THE MANUFACTURER ACKNOWLEDGES THE DEFECT AND IS NOW PROVIDING NEWLY DESIGNED REPAIR PARTS DESCRIBED AS PERMANENTLY SOLVING THE PROBLEM AND COVERED BY A 2-YEAR WARRANTY AT A COST IN EXCESS OF $5,500 RETAIL.

HYBRID DEFAULT MULTIPLE TIMES IN PAST YEARS ELECTRICAL SYSTEM? FAULT GENERATOR CHECK ENGINE LIGHT

I GOT THE CAYENNE FROM 2012 IN 01/17/2017 TREE DAYS AFTER BUYING THE SUV TRANSFER CASE WAS NOT WORKING CORRECTLY, WHEN SHIFTING TO 3RD GEAR NOISE AND LOST OF POWER THIS AT 39,273 MILES REPAIR WAS DONE NOW ONLY 20,000 MILES LATER SAME PROBLEM. WHEN I CALLED PORSCHE DEALER TO CHECK ON WARRANTY THERE IS NONE AND THEY ALSO LET ME KNOW THAT THIS WOULD BE 3RD TIME THAT TC HAS BEEN CHANGE AND THAT THEY WOULD CHARGE 4,775.00 TO REPAIR.

WHEN DRIVING CAR, IT FEELS ROUGH AND IS HARD TO ACCELERATE SO I TOOK IT TO THE DEALER AND WAS TOLD IT WAS THE TRANSFER CASE. THE TRANSFER CASE SEEMS TO BE A MANUFACTURE PROBLEM AND IS COMMON AMONG THESE CARS. IT'S UNSAFE AND ALMOST IMPOSSIBLE TO DRIVE ON THE HIGHWAY .

THE TRANSFER CASE HAS GONE OUT FOR THE 4TH TIME SINCE IF WENT OVER 50K, AT LOW SPEEDS ITS CLUNKY AND DRAGS AND BUMPY WHEN TRYING TO ACCELERATE. I FOUND OTHER INDIVIDUALS HAVING THE SAME PROBLEM MUTLI TIMES AS MYSELF AND THIS IS NOT CHEAP TO FIX. THE DEALER KNOWS THIS IS A PROBLEM BUT WILL NOT HELP WITH COST

THIS VEHICLE SUFFERS UNKNOWN HYBRID SYSTEM FAILURE. IT CAUSED THE VEHICLE TO LOSE POWER ABRUPTLY WHILE IN MOTION ON THE HIGHWAY OR ON A CITY STREET WITHOUT ANY PRIOR WARNING. THE VEHICLE COULD NOT TRAVEL MORE THAN 20 MILES ON AUTOMATIC; UNLESS IT IS SWITCHED TO MANUAL SHIFT GEAR. THIS VEHICLE HAD SUBMITTED TO THE DEALER FOR DIAGNOSIS AND CONCLUSION WAS MADE AS THIS WAS CAUSED BY THE BATTERY FAILURE. HOWEVER, WITHIN THREE WEEKS AFTER REPAIR; THE HYBRID SYSTEM FAILED AGAIN. THE TECHNICIAN THEN RE-DETERMINED THE CAUSE AS A) FAULTY HIGH POWER VOLTAGE LINE AND COMPRESSOR, AND B) REPLACE HIGH VOLTAGE LINE AND COMPRESSOR.

THE PORSCHE DEALER INFORMED ME THE BUMPING NOISE WHILE ACCELERATING IS THE TRANSFER CASE. IT IS A COMMON PROBLEM ON ALL 2012 CAYENNE CARS. THE TRANSFER CASE WILL MAKE THE BUMPING NOISE WHEN ACCELERATING. IT WILL EVENTUALLY SLIP TO THE DANGEROUS POINT. THIS IS WHEN YOU ACCELERATE INTO TRAFFIC AND THE TRANSFER CASE ONLY SLIPS AND LEAVES THE SITTING IN TRAFFIC UNABLE TO MOVE. THE REPAIR IS $5000 AND REPLACES THE TRANSFER CASE. THE NEW TRANSFER CASE CORRECTS THE DESIGN FLAW. THE FLAW WAS IN THE TRANSFER CASE VENTS THAT WOULD ALLOW WATER TO BUILD UP IN THE CASE. THE NEW CASE COMES WITH VENT TUBES INSTALLED SO THE CASE CAN VENT PROPERLY AND WATER DOESN'T BUILD UP IN THE TRANSFER CASE FLUID. IT IS A SHAME THAT THIS PROBLEM HAPPENS BETWEEN 30,000 AND 80,000 MILES. IF I PAY $60, 000 -$100,000 FOR A CAR I WOULD EXPECT TO GET PAST 100,000 MILES BEFORE A MAJOR REPAIR. HOPEFULLY I DON'T GET KILLED IN TRAFFIC WHEN IT STARTS SLIPPING MORE.

TRANSFER CASE FAILURE. CAUSES INTERMITTENT ROUGH STUTTERING WHEN DEPRESSING GAS PEDAL ON HIGHWAY ESPECIALLY ON INCLINE. CAR DEALER DID NOT DETECT PROBLEM WHEN PERFORMING DIAGNOSTICS. WENT TO ANOTHER DEALER SERVICE LOCATION. SERVICE REPRESENTATIVE DROVE THE CAR AND QUICKLY CONFIRMED THE CAUSE IS A TRANSFER CASE FAILURE. WE WERE TOLD OUR CAR CAN STALL AT ANYTIME WHICH IS A CLEAR SAFETY HAZARD. AFTER A LOT OF RESEARCH, WE FOUND OUT TRANSFER CASE FAILURE IS A CONSISTENT AND RECURRING ISSUE FOR PORSCHE CAYENNE'S MANUFACTURED IN 2011 TO 2017.
