The original Porsche leather upper dashboard has shrunk, causing exposed staples, and rippling of the leather , including rippling and bunching of the leather that is covering the passenger dash airbag assembly. I have been informed that in the event of an accident causing airbags to deploy, the passenger airbag would likely not deploy correctly, and further injury could also occur because of exposed staples and hardware that should not be exposed. My Porsche dealer and independent dealer have both advised replacement of dash (for a very large sum of money). I have also taken the vehicle to multiple upholstery shops and all have declined to fix the problem solely due to the airbag risk/liability. This is very common issue for late model porsche full leather option dashes, and specifically Cayenne models seem to be heavily affected. At this point, I am worried about the safety of my vehicle, and continue usage, and the dealer price to fix out of pocket is prohibitive (the part itself from the porsche dealer is >$6000, not including significant labor charges to remove and replace the full dash). Cayenne owners have been quoted over $10,000 to fix the issue from dealers. Thank you for your time

Porsche dash material is separating from the substrate of the structure. This material is directly between the airbag and the now loose material on the surface of the dash (leather). Porsche will not repair this and recommends a replacement at an estimated $10,000 USD. There is a significant risk to safety as the now loose upper material will interfere with the deployment of the airbag on the passenger side, adding potential harm and injury to a passenger inside the vehicle.

The leather on my Porsche Cayenne dashboard has shrunk and is pulling away from the front of the dashboard. My mechanic tells me that this is a possible safety issue because if the vehicle is in an accident, the front passenger airbag may not deploy correctly and recommends replacing (expensive). In checking various Porsche online forums, this appears to be a common issue among owners with the more expensive leather dashboards.

The contact owns a 2011 Porsche Cayenne Turbo. The contact stated that while starting the vehicle, the vehicle shuddered abnormally. Additionally, while driving, the vehicle experienced a loss of power steering assist, and the brake pedal was firm while depressed. The vehicle failed to come to a complete stop. The traction control, check engine, oil pressure, and several other unknown warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed that the passenger's side camshaft controller and bolts had failed. The dealer determined that both the driver's and passenger's side camshaft controllers and bolts needed to be replaced. The dealer replaced the camshaft adjusters and bolts under NHTSA Campaign Number: 17V368000 (Engine) associated with the VIN; however, the contact was not satisfied with the remedy for the recall. The contact stated that the dealer failed to recover all the failed bolts inside the engine. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 131,046.

My vehicle has camshaft and crankshaft correlation problems due to the well-known problem with its screws and other things. I reported it to Porsche and they told me that it has already been repaired but I don't understand how to fail again and deny help for its repair.

I have a 2011 model Porsche Cayenne S. From the service records, I can tell the car has had two transfer cases already replaced and is in need of another. The first transfer case was replaced in mid-2016 by the dealer at about 46,000 miles. The second transfer case was replaced just over 12,000 miles later, at 58,500 miles, in late 2019. Both replacements were done by the previous owner. This should have been the newest and most updated transfer case with the new control modules and GNC-coated plates, but this does not appear to have solved the problems Porsche is having with the transfer cases. It is now mid-2023, and an independent shop says I need another transfer case in my car at 76,000 miles. It is hard to believe that Porsche considered the upgraded parts (2018+) to be a permanent solution, especially when it only lasted about 17,000 miles.      I will hopefully be able to have my local dealership dissect the transfer case I am replacing so that I can learn more about what actually failed on this updated unit. Transfer cases are a major part of the vehicle and should be expected to last just as long as other major components (ex. engine, transmission). It is very unsafe when any major part of the drive train fails.  PS. One of the main reasons for purchasing this specific cayenne was because I believed the transfer case it had installed in 2019 would have solved all of these issues and I would not need to replace it again.

The contact owns a 2011 Porsche Cayenne. The contact noticed that the smoke light stop functioning. The vehicle was taken to the dealer and the fuse for the smoke light was replaced. On another occasion, the contact noticed that the passenger-side headlight to the vehicle stop functioning. The vehicle was taken to the dealer and the light bulb was replaced but the failure reoccurred, and the passenger side headlight light bulb was replaced. On another occasion, the air condition stops functioning. The vehicle was taken to the dealer who stated that the blower motor needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and stated that the VIN was not under NHTSA Campaign Number: 04V069000 (ELECTRICAL SYSTEM) and did not provide any assistance. The failure mileage was 20,000. The contact stated that the failure mileage was between 60,000 and 80,000. The recall for a faulty main wiring harness does not include the contact's VIN. The contact has concerns about the bad wiring eventually causing a fire. No repairs have been made. The contact stated the problem still persists, and informed there is a electrical problem.

2011 Cayenne Turbo: Vehicle has had recent transfer case servicing. Experiencing a grinding sensation on roundabouts, and turns that almost feels as if the brake is applied. If issue continues to worsen, it could easily cause an accident as a sudden speed reduction on a roundabout, or turn may prompt unaware/inattentive drivers to rear-end me, or worse. Dealership is citing transfer case failure, however, my vehicle is one year removed from the end of the extended warranty campaign and is no longer eligible for a replacement unit.

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.

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

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).

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 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.

TRANSFER CASE FAILURE. THERE IS AN ACKNOWLEDGMENT BY PORSCHE OF AN ASSOCIATED DEFECT OF THE TRANSFER CASE DESIGN AND A RELATED WORKSHOP BULLETIN (WB) WHEN REPLACING THE TRANSFER CASE. PORSCHE MECHANICS ARE INSTRUCTED TO REPLACE A "VENT HOSE" FOR THE TRANSFER CASE. THIS NEWLY REVISED DESIGN PART NUMBER FOR THE REVISED VENT IS 958-301-047-10. THE REASON: THE ORIGINAL DESIGN FOR CAYENNE 958 PORSCHE TRANSFER CASES HAD THE HOSE ENDING ON THE LOWER (CLOSER TO THE GROUND) SIDE OF THE TRANSFER CASE. THE NEW HOSE ENDS ON THE UPPER (FURTHER FROM THE GROUND) SIDE OF THE TRANSFER CASE. PORSCHE DETERMINED THAT MOISTURE WAS GETTING SUCKED INTO THE CASES AND CAUSING FLUID CONTAMINATION. SINCE THE TRANSFER CASE USES A "MULTIPLATE WET CLUTCH", MOISTURE COULD PREMATURELY CORRODE OR ALLOW RUST TO FORM, WHICH COULD CAUSE THE CLUTCH TO BIND AND WORK ERRATICALLY. THESE ARE SYMPTOMS DESCRIBED BY MULTIPLE OWNERS OF 958 CAYENNES DISCUSSED IN PORSCHE FORUMS (E.G. RENNTECH.ORG, RENNSLIST.COM, ETC.). THIS REVISED VENT DEVELOPED BY PORSCHE TO REPLACE THE EXISTING DESIGN, SHOULD BE COVERED BY PORSCHE. MOREOVER, OWNERS OF 958 CAYENNES WHO HAVE EXPERIENCED FAILURES OF THE TRANSFER CASE AND SUBSEQUENT REPLACEMENT OF THE TRANSFER CASE AND THE NEWLY DESIGNED HOSE, SHOULD BE REIMBURSED FOR THE FULL COST OF THE REPLACEMENT TRANSFER CASE AND THE HOSE. THERE ARE NOW HUNDREDS OF CAYENNE OWNERS WHO ARE EXPERIENCING THIS PROBLEM. MOREOVER, THE MAINTENANCE SCHEDULE DOES NOT CALL FOR ANY PREVENTATIVE FLUID CHANGES OF THE TRANSMISSION OIL. THIS SHOULD BE REVISED AND RECOMMENDED SERVICING SHOULD BE PRESCRIBED (E.G., EVERY 10,000 MILES). THE FAILURE OF THE TRANSFER CASE COULD CAUSE VEHICLES TO LURCH OR REACT IN AN ERRATIC OR UNSAFE CAPACITY ACROSS THE SPECTRUM OF OPERATION, INCLUDING HIGHWAY SPEED DRIVING. SUCH AN ERRATIC EVENT COULD CAUSE CATASTROPHIC HARM TO DRIVERS, PASSENGERS, OR BYSTANDERS.
