2011 Porsche CayenneRecalls, problems, MPG & safety

“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.”

“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…”

“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…”
