2011 Porsche Cayenne transmission problems

Filed May 9, 2023 · Transmission · SC

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.Â

2011 Cayenne Turbo: Vehicle has had recent transfer case servicing. Experiencing a grinding sensation on roundabouts, and turns that almost feels as if the brake is applied. If issue continues to worsen, it could easily cause an accident as a sudden speed reduction on a roundabout, or turn may prompt unaware/inattentive drivers to rear-end me, or worse. Dealership is citing transfer case failure, however, my vehicle is one year removed from the end of the extended warranty campaign and is no longer eligible for a replacement unit.

Very dangerous situation with my 2011 cayenne s -- just replaced transfer case in july 2017 (less than 3 years ago) due to unexpected pausing/hesitating when accelerating, and now the exact same problem occurred again!!! Searched online and read similar comments made by others with the same problem. Porsche has to recall and fix this -- it's very dangerous and could be life-threatening.

Transfer case while driving started jerking while on the highway.. It has slowly gotten worse and has become dangerous to drive as I almost have got into a few accidents due to the surge in sudden jerks. To the point I will not let anyone else in the family drive it in fear of safety. I took it to the shop and was told it needs a new $5,000 transfer case. A local porsche shop told me this is a known manufacturer's issue and very common in these cars - due to a known defect in the transfer case and can be dangerous, but no recall (known) so far. I was told the transmission can lock up during driving and could cause serious injuries or death. I am now scared to drive it. I have a luxury vehicle that I am paying insurance on of which I can't drive that is useless sitting in my garage. This was my 1st porsche and sadly may be my last if this is not resolved. I have read tons of reports on forums citing this same problem. If this is such a known hazard what will it take to have porsce do the right thing and recall & get this fixed? I pray they are not waiting for a death first.

Car had transfer case replaced at 20k and now told to do again at 46k. Sudden jerk and loss of acceleration when car is going from 3 to 4 gear or under 25mph. Issue seems to be pretty much on most cayennes and cost $5000 to repair. Mine is a 2014 model

Transfer case has failed, jerking and interruption of accelerations. Almost caused a wreck. Very well known problem and there are a lot of similar complaints on the federal safety agency complaint log system as well as documented online. I called porsche and they denied knowing about any problem with it but you can call the service departments at any porsche dealer and they immediately know about the problem. I called two and they know of it as a common problem. Extremely expensive to correct ($5,000).

I have had the transfer case replaced in this vehicle twice in the last 25k miles. At 65k miles the car is doing the familiar grinding and surging again, evident it will need a third $5-6000 transfer case. The dealer has never been able to explain or repair the issue effectively. The manufacturer does not reply to inquiries, it is my request that they be forced to provide a permanent, reliable fix for this issue. I'm worried this could cause a safety issue under the right circumstance since it happens while the car is in motion. The mechanics at the various dealers have told me its a well known issue spanning porsche suvs from 2008 through the present. Gotta wonder what this manufacturer is thinking here and why they are hiding the details.
