2011 Porsche Cayenne

THE ALUMINUM BOLTS ON THE TIMING COVER ARE BROKEN CAUSING AN OIL LEAK. IF THE ALL BOLTS ARE MADE OF ALUMINUM THEN WHAT ABOUT THE TRANSFER CASE? I'VE HEARD ABOUT NEAR ACCIDENTS BECAUSE OF BOLTS BREAKING EITHER BECAUSE OF THE MATERIAL DIFFERENCE BETWEEN THE BOLTS AND THE MAGNESIUM IN THE MOTOR. IT HAS OCCURRED ON OTHER MODELS OF PORSCHES. PORSCHE SHOULD RECALL AND FIX THE ALUMINUM BOLTS ON ALL PARTS.

VERY DANGEROUS SITUATION WITH MY 2011 CAYENNE S -- JUST REPLACED TRANSFER CASE IN JULY 2017 (LESS THAN 3 YEARS AGO) DUE TO UNEXPECTED PAUSING/HESITATING WHEN ACCELERATING, AND NOW THE EXACT SAME PROBLEM OCCURRED AGAIN!!! SEARCHED ONLINE AND READ SIMILAR COMMENTS MADE BY OTHERS WITH THE SAME PROBLEM. PORSCHE HAS TO RECALL AND FIX THIS -- IT'S VERY DANGEROUS AND COULD BE LIFE-THREATENING. *TR

TRANSFER CASE WHILE DRIVING STARTED JERKING WHILE ON THE HIGHWAY.. IT HAS SLOWLY GOTTEN WORSE AND HAS BECOME DANGEROUS TO DRIVE AS I ALMOST HAVE GOT INTO A FEW ACCIDENTS DUE TO THE SURGE IN SUDDEN JERKS. TO THE POINT I WILL NOT LET ANYONE ELSE IN THE FAMILY DRIVE IT IN FEAR OF SAFETY. I TOOK IT TO THE SHOP AND WAS TOLD IT NEEDS A NEW $5,000 TRANSFER CASE. A LOCAL PORSCHE SHOP TOLD ME THIS IS A KNOWN MANUFACTURER'S ISSUE AND VERY COMMON IN THESE CARS - DUE TO A KNOWN DEFECT IN THE TRANSFER CASE AND CAN BE DANGEROUS, BUT NO RECALL (KNOWN) SO FAR. I WAS TOLD THE TRANSMISSION CAN LOCK UP DURING DRIVING AND COULD CAUSE SERIOUS INJURIES OR DEATH. I AM NOW SCARED TO DRIVE IT. I HAVE A LUXURY VEHICLE THAT I AM PAYING INSURANCE ON OF WHICH I CAN'T DRIVE THAT IS USELESS SITTING IN MY GARAGE. THIS WAS MY 1ST PORSCHE AND SADLY MAY BE MY LAST IF THIS IS NOT RESOLVED. I HAVE READ TONS OF REPORTS ON FORUMS CITING THIS SAME PROBLEM. IF THIS IS SUCH A KNOWN HAZARD WHAT WILL IT TAKE TO HAVE PORSCE DO THE RIGHT THING AND RECALL & GET THIS FIXED? I PRAY THEY ARE NOT WAITING FOR A DEATH FIRST. *TR

COOLANT LEAKS WHILE VEHICLE IS STATIONARY. LEAK IS DUE TO FAULTY PLASTIC THAT WAS REDESIGNED TO METAL TUBING DUE TO COMMON REPORTED ISSUES. PLASTIC TUBING CONNECTED TO COOLANT SYSTEM WILL BECOME BRITTLE AND CRACKED, CAUSING OVERHEATING AND LOST OF COOLANT. THIS ISSUE IS COMMONLY REPORTED ABOUT THE 2011 CAYANNE WITH A DEALERSHIP COST OF UP TO $4500.

TRANSFER CASE HAS FAILED, JERKING AND INTERRUPTION OF ACCELERATIONS. ALMOST CAUSED A WRECK. VERY WELL KNOWN PROBLEM AND THERE ARE A LOT OF SIMILAR COMPLAINTS ON THE NHTSA COMPLAINT LOG SYSTEM AS WELL AS DOCUMENTED ONLINE. I CALLED PORSCHE AND THEY DENIED KNOWING ABOUT ANY PROBLEM WITH IT BUT YOU CAN CALL THE SERVICE DEPARTMENTS AT ANY PORSCHE DEALER AND THEY IMMEDIATELY KNOW ABOUT THE PROBLEM. I CALLED TWO AND THEY KNOW OF IT AS A COMMON PROBLEM. EXTREMELY EXPENSIVE TO CORRECT ($5,000).

I HAVE HAD THE TRANSFER CASE REPLACED IN THIS VEHICLE TWICE IN THE LAST 25K MILES. AT 65K MILES THE CAR IS DOING THE FAMILIAR GRINDING AND SURGING AGAIN, EVIDENT IT WILL NEED A THIRD $5-6000 TRANSFER CASE. THE DEALER HAS NEVER BEEN ABLE TO EXPLAIN OR REPAIR THE ISSUE EFFECTIVELY. THE MANUFACTURER DOES NOT REPLY TO INQUIRIES, IT IS MY REQUEST THAT THEY BE FORCED TO PROVIDE A PERMANENT, RELIABLE FIX FOR THIS ISSUE. I'M WORRIED THIS COULD CAUSE A SAFETY ISSUE UNDER THE RIGHT CIRCUMSTANCE SINCE IT HAPPENS WHILE THE CAR IS IN MOTION. THE MECHANICS AT THE VARIOUS DEALERS HAVE TOLD ME ITS A WELL KNOWN ISSUE SPANNING PORSCHE SUVS FROM 2008 THROUGH THE PRESENT. GOTTA WONDER WHAT THIS MANUFACTURER IS THINKING HERE AND WHY THEY ARE HIDING THE DETAILS.

TL* THE CONTACT OWNS A 2011 PORSCHE CAYENNE. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT DEPRESSED THE ACCELERATOR PEDAL AND THE VEHICLE STARTED TO JERK. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO A DEALER TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 80,000.
