  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.

• 11/26/2024· AIR BAGS,UNKNOWN OR OTHER

  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

• 11/19/2024· AIR BAGS,UNKNOWN OR OTHER

  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.

I CALLED TWO AND THEY KNOW OF IT AS A COMMON PROBLEM. EXTREMELY EXPENSIVE TO CORRECT ($5,000).

• 09/18/2011· ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,UNKNOWN OR OTHER

  THE FACTORY PROGRAMMING OF THE COMPUTER AND SPEED CONTROL IS INCORRECT. PORSCHE STATES THAT THE VEHICLE IS OPERATING WITHIN CHARACTERISTICS AND SPECIFICATIONS [AND ACCORDING TO US LAW A VARIANCE OF UP TO 18% IS ALLOWED IN THE SPEEDOMETER.] HOWEVER, PORSCHE HAS TAKEN THE US LAW TO MEAN THAT IT IS ALLOWED TO INTENTIONALLY PROGRAM ITS COMPUTERS TO THE SAME SPECIFICATIONS AS ANALOG GAUGES. PORSCHE CANNOT DEMONSTRATE THAT THE INACCURACY IN THE SPEEDOMETER IS NOT EFFECTING THE HYBRID OPERATIONS OF THE VEHICLE. THE INACCURATE SPEED READING MAY ALSO CREATE INACCURATE ODOMETER READINGS. IN ADDITION THE VEHICLE HAS PROBLEMS WITH HARD BRAKING WHICH IS ESPECIALLY PRONOUNCED WHEN THE VEHICLE IS UNDER CRUISE CONTROL. AND IN CERTAIN INSTANCES THERE IS LAG ON ACCELERATION. PORSCHE HAS REFUSED TO REPROGRAM THE SPEEDOMETER CONTROLS TO ACTUAL SPEED. GIVEN THAT THE ONLY PROBLEMS ON THE VEHICLE ARE RELATED TO THE SPEED OF THE VEHICLE, IT SEEMS THAT PORSCHE SHOULD BE CAPABLE OF PROVIDING A SOLUTION BY REPROGRAMMING THE ONBOARD COMPUTERS. *TT

  WHILE DRIVING ON THE ROAD IN A REMOTE NATIONAL PARK, THE TUBING THAT RETURNS COOLANT TO THE ENGINE BLOCK FROM THE RADIATOR ON MY 2011 PORSCHE CAYENNE S COMPLETELY BLEW APART. THIS ALUMINUM TO ALUMINUM TUBING CONNECTION APPEARS TO HAVE BEEN HELD TOGETHER EXCLUSIVELY BY A THIN, INCOMPLETE RING OF EPOXY GLUE. THIS IS GROSSLY SUBSTANDARD ENGINEERING FOR ANY SUCH VITAL CONNECTION WITHIN THE ENGINE. PORSCHE HAS NEGLECTED TO REPAIR THIS KNOWN ISSUE IN MODEL YEARS SUCH AS MINE, BUT HAS CHANGED ITS DESIGN IN THE SUBSEQUENT MODEL YEARS (LIKELY BECAUSE THEY REALIZED THIS WAS DANGEROUS AND SUBSTANDARD ENGINEERING). THEY HAVE NOT SENT OUT ANY BULLETIN OR RECALL TO ADVISE DRIVERS OF THIS DEFECTIVE CONSTRUCTION OR PREEMPTIVELY REPAIR IT. I WAS LEFT STRANDED IN A DESERT WHERE I HAD TO WALK FOR HOURS TO GET HELP AND HAD TO HAVE $1000 TOW TO THE NEAREST CITY, ALL BECAUSE OF THIS DANGEROUS DESIGN AND CONSTRUCTION OF WHICH PORSCHE IS ALREADY AWARE.

  THE CAR STOPPED WHILE BEING DRIVEN IN TRAFFIC ON A BUSY SUBURBAN ROAD. THE CAR WOULD NOT RESTART. RIGHT BEFORE THE CAR SUDDENLY STOPPED THE PSM LIGHT CAME ON. THIS WAS THE ONLY THING THAT OCCURRED PRIOR TO THE SUDDEN STOP. THE CAR WAS PUSHED OUT OF THE ROAD AND FLAT BEDDED TO PAUL MILLER PORSCHE IN PARSIPPANY, N.J. THE SERVICE TECHNICIAN(S) FOUND THAT AT LEAST ONE ALUMINUM BOLT FROM THE CAM SHAFT ADJUSTER HAD SHEARED OFF AND FELL THROUGH THE ENGINE CAUSING COMPLETE ENGINE FAILURE. THE ONLY WAY TO REPAIR THE CAR WAS TO REPLACE THE ENGINE. THE CAR WAS PURCHASE BRAND NEW ON JUNE 15, 2011. THE CAR HAD BEEN SPECIAL ORDERED SEVERAL MONTHS PRIOR TO THE DELIVERY DATE. AFTER THIS INCIDENT, I RESEARCHED THIS ISSUE. IT APPEARS THAT PORSCHE CAYENNES AND PANAMERAS MANUFACTURED DURING THE SAME TIME PERIOD OUR CAR WAS MADE WERE RECALLED IN CHINA FOR THIS EXACT SAME ISSUE-ALUMINUM CAMSHAFT ADJUSTER BOLTS SHEARING OFF INTO THE ENGINE AND CAUSING TOTAL ENGINE FAILURE. THIS CAR WAS OUT OF THE PORSCHE 4 YEAR/50K WARRANTY PERIOD. I NOTIFIED PORSCHE NORTH AMERICA OF THIS INCIDENT AND THEY REFUSED TO REPLACE THE ENGINE. THE CAR WAS COVERED UNDER OUR GEICO MECHANICAL BREAKDOWN INSURANCE. GEICO SENT OUT INSPECTORS TO EXAMINE THE CAR AND DEEMED IT A TOTAL LOSS. WE SURRENDERED THE CAR TO GEICO AND WERE PAID WHAT THEY DEEMED THE CAR WAS WORTH. THE LAST TIME WE SAW THE CAR WAS AT PAUL MILLER PORSCHE IN PARSIPANNY, N.J. ON JULY 26TH WHEN WE EMPTIED IT OF OUR PERSONAL BELONGINGS. LUCKILY NO ONE WAS HURT IN THIS INCIDENT. OBVIOUSLY A CAR SUDDENLY STOPPING WHILE BEING DRIVEN IS HUGE DANGER. HAD THIS OCCURRED ON A HIGHWAY OR IN FASTER TRAFFIC THE RESULTS COULD HAVE BEEN CATASTROPHIC.

  THERE HAVE BEEN INCREASING REPORTS OF VARIOCAM CAMSHAFT DRIVE BOLT FAILURES ON THE 2011 PORSCHE CAYENNE V8 ENGINES. WHEN THESE BOLTS FAIL, ENGINE DAMAGE OCCURS, AND THE ENGINE TYPICALLY STOPS RUNNING. IN THE CASE OF THE TURBO MODEL - THIS CAN ALSO RESULT IN THE LOSS OF BRAKING ABILITY SINCE THE BRAKES ARE POWERED OFF A CAMSHAFT. THERE IS ALSO A LOSS OF POWER STEERING - MEANING YOU HAVE A 4,500LB VEHICLE WITHOUT BRAKES OR STEERING. PORSCHE HAD A LIMITED "WORKSHOP CAMPAIGN" FOR THESE VEHICLES THAT ADDRESSED A CERTAIN RANGE OF VIN# IN THE USA. IT IS WC-22 (I'M ATTACHING A PDF OF IT.) THE FAILURES ARE NOW BEING REPORTED WITH INCREASING FREQUENCY IN VIN#'S NOT COVERED BY THIS WORKSHOP CAMPAIGN. THE CAMPAIGN INVOLVES REPLACING THE VARIOCAM ASSEMBLY WITH ONE ASSEMBLED WITH STEEL BOLTS RATHER THAN ALUMINUM BOLTS. EARLIER VERSIONS OF THIS ASSEMBLY ALSO USED STEEL BOLTS, AND THE FAILURES APPEAR LIMITED TO ONES WHERE THE ALUMINUM BOLTS WERE USED. THE MOST COMPLETE DISCUSSION ON THIS CAN BE FOUND AT: HTTP://WWW.6SPEEDONLINE.COM/FORUMS/CAYENNE/319690-SNAPPED-CAMSHAFT-ADJUSTER-BOLT-ENGINE-BRAKE-HYDRAULICS-FAILURE.HTML THERE ARE OTHER WEBSITES AND DISCUSSIONS ON THE SAME FAILURE. HERE IS AN ARTICLE ON THE RECALL PORSCHE DID IN CHINA FOR THE SAME PROBLEM: HTTP://EUROPE.AUTONEWS.COM/ARTICLE/20150209/ANE/150209861/PORSCHE-WILL-RECALL-SOME-PANAMERA-CAYENNE-MODELS-IN-CHINA MINE HAS NOT FAILED YET - BUT IT APPEARS TO BE JUST A MATTER OF TIME, MINE HAS THE ALUMINUM BOLTS IN THE ASSEMBLY. I WOULD ASK THAT PORSCHE EXTEND THE WORKSHOP CAMPAIGN TO ALL THE VEHICLES WITH THE ALUMINUM BOLTS USED IN THE VARIOCAM ASSEMBLY. THE FAILURE OF BOTH BRAKES AND STEERING THAT OCCURS WHEN THESE BOLTS FAIL IS AN OBVIOUS SAFETY ISSUE WITH THESE VEHICLES. IT MAKES ME HESITANT TO DRIVE THE VEHICLE. I'VE ASKED THE LOCAL DEALER ABOUT IT, AND THEY CLAIM MY VEHICLE IS NOT EFFECTED.

THIS ENDED UP COSTING ME APPROXIMATELY $7500 OUT OF POCKET (IN ADDITION TO SEVERAL EMOTIONAL DAMAGE DUE TO FINANCIAL CONSTRAINTS AND THE IMMEDIATE DANGER WHEN THE ENGINE FAILED AT HIGHWAY SPEED IN THE FAR LEFT LANE). PORSCHE HAS SUBSEQUENTLY ISSUED A RECALL (RECALL AH-08 AND NHTSA CAMPAIGN 17V368000) BUT HAD NOT CONTACTED AFFECTED OWNERS YET. I'D LIKE A FULL REFUND OF MY EXPENSES PLUS INTEREST.

  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.
