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.

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.

The engine of my Porsche Cayenne turbo was shut off completely while turning left on a two-lane highway. The opposite car had to veered off to avoid collision. The car kept moving forward until it hit the curb.
