2012 Porsche Cayenne S Hybrid problems

“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,”

“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…”

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

“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.”

“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.”
