What 28 owners told NHTSA about the 2012 Porsche Cayenne Turbo

Porsche dashboard leather shrunk and staples pulled out around passenger side airbag. I was told that if the vehicle was in an accident the airbag might not deploy correctly. The Porsche dealer looked at it and recommended replacing it. This is a very common issue.

The transfer case on my car has been confirmed by two different mechanics that it needs to be replaced. Porsche no longer makes or sells the original transfer case and components, so the entire transfer case needs to be replaced, at a cost of approximately $5,000. Porsche extended the warranty for the transfer case for up to 10 years, but I was never notified or made aware of this extension. Because my transfer case issue was identified 6 months outside of the extended warranty, the full cost of this repair is my liability. I believe that Porsche is aware that the original transfer case has design flaws and reliability issues, and while they did extend warranty coverage, they made no effort to communicate the extension. If so, I would have had the transfer case inspected while still under warranty.

I own a 2012 Porsche Cayenne. Transfer case broke at 33,000 miles and was replaced by the dealer, and now it broke again at 55,000 miles. Repair cost is $6,340 plus tax. It broke under the warranty period but Porsche gave me the runaround and told me they wouldn't check it until after some body damage was complete (more details below). Honestly feel like I'm getting gouged with faulty parts. Many other Porsche Cayenne owners seem to be reporting this problem on forums. (e.g. https://rennlist.com/forums/cayenne-958-2011-2018/1290994-transfer-case-failure-2.html) More details - 1. We asked the Porsche dealership to review the car for mechanical issues and repair bumper body damage while the transfer case was under warranty. 2. The Porsche dealer declined to review any mechanical issues until the bumper body damage repair was complete. 3. The Porsche was taken in for service to repair the body work first in late March per Porsche's guidance while the transfer case was still under warranty. 4. The body work was delayed due to Porsche's supply chain issues, and by the time it was complete it was after May 2nd which was when the warranty expired for the transfer case. 5. When the Porsche dealer received the car after May 2nd it identified the transfer case broke. This has been a recurring issue with a car as one transfer case broke at ~33,000 miles and was replaced at a Porsche dealership. Now the second transfer case broke at 55,000 miles (this case only lasted 22,000 miles). 6. Porsche declined to make an exception to the warranty and recommends replacing the transfer case at a price of $6,340 plus tax which will likely last for between 22,000 - 33,000 miles based on prior data points.

RECALL WORK MISHANDLED AND CAUSED PROBLEM: I WENT TO PORSCHE FOR A REGULAR OIL CHANGE. THEY SAID THAT THERE IS AN ACTIVE RECALL ON CAMSHAFT AND THEY CAN ALSO BE PERFORMED WHILE THE CAR IS IN. NOW WHEN I WENT TO GET MY CAR BACK THEY SAID THE ENGINE LIGHT WAS ON AND WHEN THEY CHECKED THE TECH SAYS THE PARTS SEEMS TO BE ALL NEW AND IT WAS DONE AT A DIFFERENT WORK SHOP. THEY ASKED ME TO GO TO THE SHOP AND CHECK WITH THEM. BUT I TOLD THEM IT WAS DONE FEW MONTHS BACK AND I HAD NO ISSUES AT ALL AND THE CAR DIDNT HAVE ANY ISSUES WHEN I GAVE IT FOR OIL CHANGE( NO CHECK ENGINE LIGHT). ALSO WHEN I ENTERED THE CAR I WAS ABLE TO SMELL A THICK OIL SMELL WHICH I INFORMED BECKY THE SERVICE CONSULTANT AND I WAS TOLD THAT IT COULD BE OIL SPILL WHEN THEY DID OIL CHANGE. I ASKED IF THE ISSUE MIGHT BE RELATED TO THE CAMSHAFT WORK THEY DID BUT THEY PROMPTLY SAID IT WAS NOT RELATED. SO I TOOK THE CAR TO THE AUTO SHOP ( PORSCHE CERTIFIED SHOP) TO HAVE THEM CHECK IT. THE SHOP CHECKED AND DIDNT FIND ANY ISSUES WITH THEIR PARTS THEY REPLACED SINCE IT WAS COVERED UNDER WARRANTY THEY WENT AHEAD REPLACED THE PART AND THE CHECK ENGINE LIGHT SIGN DIDNT GO AWAY, SO THEY PERFORMED SMOKE TEST AND FOUND OUT THE INTAKE LEAK COMING FROM A SENSOR SEAL ON THE VALVE COVER. THEY SAID THIS IS BECAUSE OF THE CAMSHAFT WORK THAT HAS CAUSED A LARGE AIR LEAK IN THE ENGINE SETTING THE CHECK ENGINE LIGHT. ALSO WHEN THEY CHECKED THE COVERS THEY FOUND THAT THERE WERE 2 ALUMINIUM SCREWS THAT WERE BROKEN . WHEN THE COVER WAS REMOVED THE ALUMIMIUM SCREWS WERE SUPPOSED TO BE REPLACED WHICH WERE NOT AND THE OLD ONES WERE USED WHICH LEAD TO TENSION AND THEY WERE BROKEN THE AUTO SHOP HAS PROVIDED ME WITH ALL THE DETAILS AND EVIDENCE OF THE ISSUE ALONG WITH VIDEO TO SHOWCASE.I NEED NHTSA ASSISTANCE TO HELP ME GUIDE ON THIS ISSUE CAUSED BY THE DEALERSHIP TO MY CAR WHILE WORKING ON THE RECALL.

I HAVE A 2012 PORSCHE CAYENNE S HYBRID. IT IS SUFFERING FROM THE DEFECT DESCRIBED IN THIS RECALL CAMPAIGN: 17V36800. THE BOLTS THAT HOLD THE CAMSHAFT IN PLACE HAVE SHEARED OFF. PORSCHE IS REFUSING ANY TYPE OF CONSIDERATION BECAUSE THE VIN IS NOT IN THE RECALL LIST, BUT IT IS IN THE YEAR OF THE RECALL AND SUFFERS FROM THE ISSUE. I WAS DRIVING THE VEHICLE ON THE HIGHWAY AND THE CHECK ENGINE LIGHT CAME ON. THE VEHICLE LOST POWER AND THE ENGINE STARTED KNOCKING. I WAS ABLE TO COAST TO THE SHOULDER. I HAD TO CALL MY WIFE AND HAVE IT TOWED. THE DEALER TOLD ME IT WOULD COST 14K+ TO REPAIR AND THEY WOULD NEED THE VEHICLE FOR A MONTH. *TR

THE TRANSFER CASE IS FAULTY. IT WAS REPLACED AT 26,000 MILES AND NOW IT IS ACTING THE SAME WAY AGAIN AT 48.000 MILES. I WAS ENTERING THE HWY AND THE CAR JUMPED FORWARD AND SUDDENLY LOST POWER BEFORE JUMPING INTO GEAR. THIS IS NOT SAFE CONSIDERING THERE WAS A CAR IN FRONT OF ME AND BEHIND. DID NOT CAUSE AN ACCIDENT BUT COULD HAVE. DEALER ADMITS THE TRANSFER CASE HAS BEEN A CONSTANT PROBLEM WITH 2011-2017 CAYENNE BUT REFUSES TO TOTALLY COVER REPLACEMENT. THIS IS MY SECOND ISSUE WITH THE TRANSFER CASE AND AFTER SOME LIGHT RESEARCH HAVE COME ACROSS MANY OWNERS WITH ANYWHERE BETWEEN 1 AND 4 REPLACEMENTS. PORSCHE WILL NOT COVER THE TOTAL COST OF THE REPAIR (APPROX. $6500). HOW CAN A COMPANY LIKE PORSCHE BE SO ARROGANT AS TO UNDERSTAND AND ACCEPT IT IS A FAULTY DESIGN BUT NOT MAKE RESTITUTION TO ITS LOYAL CUSTOMERS,

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.

PORSCHE CAYENNE 2012. HAS TRANSMISSION CASING ISSUES AND THEY ARE NOT RECALLING IT! HAD TRANSMISSION CASING REPLACED WITH UNMODIFIED PART AND IN LESS THAT 25K ITS BROKEN AGAIN. WORRY ABOUT MY SAFETY ON THE ROAD AS IM TRAVELING WITH KIDS AND ELDERLY A LOT. THEY COVERED FIRST EMPLACEMENT AS THE VEHICLE WAS UNDER WARRANTY, BUT REFUSE TO COVER SECOND REPLACEMENT LABOR COSTS! ITS UNACCEPTABLE! PORSCHE DOES NOT HONOR THEIR QUALITY, WHEN THE PART WAS REPLACED UNMODIFIED IN 2015, THEY WERE FULLY AWARE THAT THIS WOULD BE A PROBLEM DOWN THE ROAD AND SURE ENOUGH, IT IS!! $650 DOLLARS IN LABOR MUST HAVE BEEN COVERED AS WAS THE SECOND REPLACEMENT PART!!
