Documenting this common transfer case problem. Felt and heard shutter/noise at slow speeds when driving slow and jerky movement upon accelerating. Car had only 40k miles and unluckily just past warranty. Replaced transfer case for $4500 in Sep 2018 and now in Jul 2020, another 14k miles later, I'm starting to hear similar symptoms brewing. . . Not a good sign. Porsche should give replacement transfer case another 4 years warranty instead of just 1 year.

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

Multiple transfer case failures. First at 50k miles (slipping between gears, followed by a severe jolt as the gear finally changed)�transfer case was replaced at my expense ($7000k later). Second failure occurred less than 6 months later at 55k miles (severe jolt when shifting from 3rd to 4th gear)�transfer case replaced under parts warranty. Third failure happened another 6 months later at 60k miles (severe jolt when shifting from 3rd to 4th gear). This last failure�yet to be fixed�has happened while I am on a road trip, and it risks me being stranded in the middle of nowhere. This issue is rampant among 958s. Porsche really needs to step up and fix this issue. It's reported rampantly on forums, with many owners reporting multiple successive failures like I have experienced.

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 manufaturer'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.

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,.

The contact owns a 2013 Porsche Cayenne. While driving, a loud unknown noise was heard from back of the vehicle. The vehicle requires that the transfer case needed to be replaced. The vehicle was not repaired. The dealer and manufacturer were not made aware of the failure. The failure mileage was approximately 70000. This is the fourth transfer case that the vehicle has required.

At about 25,000 the Cayenne started making bump upon acceleration and especially when turning. I understand this can be a safety issue unless addressed . The dealer diagnosed the problem as the transfer case which was replaced. Now we have 49,000 miles on the vehicle and it is starting to exhibit the same transfer case symptoms as before. In googling the internet this problem seems to be quite prevalent with both the Porsche Cayenne and macan. Moreover, the cost replace a transfer case is in the $5,000 when our of warranty which my 2014 is now. Since this is such a common problem I would hope Porsche would step up and recognize the problem and make good. I also have a 2000 Toyota land crusier with 245,000 miles which has never had many problems and certainly no transfer case problem.

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 ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

The transfer case in this car is failing at 53,000 miles causing unsafe, jerking acceleration leading to total breakdown/shutdown if not corrected. Numerous owners experience the same issue. The manufacturer acknowledges the defect and is now providing newly designed repair parts described as permanently solving the problem and covered by a 2-year warranty at a cost in excess of $5,500 retail.

Tl-the contact owns a 2013 Porsche Cayenne. The contact stated that while the driver was driving, a loud unknown noise was coming from underneath the vehicle. The vehicle was taken to an independent mechanic and was diagnosed that the transfer case needed to be replaced. The vehicle was not repaired and was not taken to a dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 85,000. Aw.

Purchased a 2013 Cayenne Porsche gts with 67k miles on it. Noticed a kind of thumping sound when accelerating, usually appearing at 3k rpms. Vehicle shudders and almost feels like the transmission is slipping. Took the vehicle to a mechanic to diagnose the fault and they immediately knew what it was, engine transfer case failure. This is due to a design flaw allowing water into the transfer case that Porsche is aware of and yet to address. On some occasions Porsche will pay for the $5k repair but the part is still replaced with a transfer case with the same flaw. Transfer case failure can lead to a sudden lose of power and potentially cause death or serious injury if someone is traveling at highway speeds. Highly recommend addressing this with a recall for 2013 and 2014 Cayennes. I have experienced sudden lose of power due to transfer case failure, neatly resulting in a highway collision.

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 NHTSA 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).

42,000 miles on the 2016 Cayenne gts. $110,000 original sticker. Transfer case needed to be replaced ($5,000+ charge). Service rep told me they replace 5 transfer cases each week at just their dealership. Clearly a defect that should be subject to recall. He knew in 5 seconds what the problem was when I originally called to schedule an appointment. Porsche USA refused to take responsibility for the cost of repair. Warranty expired 5/31/19. Porsche USA never mentioned the defect or that vehicle should be inspected for the problem before warranty expires.

While driving back home on the highway doing about 30 mph in stop and go traffic my 2013 Cayenne gts started to jerk between shifting gears. I thought it was a bumpy road at least but then after the traffic was over and I was able to pick up some speed to up to around 40-45mph the car shut off in the middle of the highway not knowing what to do. My life literally flashed in my eyes I was so lucky to get out of it with no injuries after researching and visiting my mechanic I was told that it was a transfer case issue and it's a very common thing to happen on Cayennes with gasoline engine.

Transmission transfer case issues immediately after acceleration between 3rd and 4th gear. Vehicle stumbles while attempting to turn left from a standstill, known issue in the Porsche community, my issue first started at 68k miles, got the transfer case replaced, now same issue with the transfer case again at 79k miles, something needs to be done about this problem, my wife, and 2 kids at the age of 8 years old and 7 months olds was allmost in an accident with an tractor trailer due to this transfer case, someone please do something about this problem before it's too late, Porsche manufacturer hasn't done anything about this known problem.

Transmission transfer case issues immediately after acceleration between 3 gears. . . Car transmissions "stumbles" (transmission locking). Well known issue in the Porsche community and Porsche solution is does not fix the issue. No engine error codes issued as well. Porsche says cannot duplicate problem. This has been happening for quite a while until I researched the issues online. Previouse recall # 03v351000 - Porsche will not currently honor this recall.

Failure of transfer case at 51,000 miles and again at 78,000 miles. Porsche acknowledges problem nationwide but will not cover repair. Vehicle shutters/stutters and does not shift into gears (4 to 5). This failure is described countless number of times on the internet in various forums. Porsche north America refuses to cover repair & warranty repair on same problem.

Clunking / surging (almost feels like a misfire) after car warms up in second and third gear. Seems to be with the transfer case. Purchases car used 30 days ago and this issue started to appear after I had the vehicle and driving it for a couple of days. Now find that this is a common issue with Cayennes.

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.

The transfer case in this car is failing at 53,000 miles causing unsafe, jerking acceleration leading to total breakdown/shutdown if not corrected. Numerous owners experience the same issue.

Car lurches starting around 25 miles per hour and continuing until reaching a cruising speed 50 or thereabouts. Took it in for an oil change at a german car repair company and asked them to evaluate my findings. The transfer case needs to be replaced. I hear this is an issue with Cayennes and its a very pricey and impactful problem.

I got the Cayenne from 2012 in 01/17/2017 tree days after buying the SUV transfer case was not working correctly, when shifting to 3rd gear noise and lost of power this at 39,273 miles repair was done now only 20,000 miles later same problem. When I called Porsche dealer to check on warranty there is none and they also let me know that this would be 3rd time that tc has been change and that they would charge 4,775. 00 to repair.

Rumbling noises in drivetrain, transfer case bad.

Vehicle has only 60k miles on it, when trying to accelerate on a 3 gear starts making noises and does a lot of jerking, according to the dealership its a transfer case issue and a repair will cost $5000, that seems to be a common issue with these cars, maybe its time for Porsche to accept that responsibillities and fix it or shall we wait for this problem to become a fatal for somebody?.

Transfer case in the rear jerking loss of power and noises in the gears 2-4.

When driving car, it feels rough and is hard to accelerate so I took it to the dealer and was told it was the transfer case. The transfer case seems to be a manufacture problem and is common among these cars. It's unsafe and almost impossible to drive on the highway .

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.

When starting to move a noise is heard. Diagnosed as a problem with the transfer case. Transfer case had to be replaced at 42,900 miles.

Failure of transfer case in transmission at 74000 miles. This is a well described problem and there are hundreds of similar complaints on the internet in Porsche Cayennes. Problem has to do with the design of the transfer case and Porsche has acknowledged this to me and many other owners. As a result of the problem the vehicle can lurch forward and also fail to accelerate causing safety issues. Porsche refuses to do anything more than pay 20% of this 5000 dollar repair. I urge the NHTSA to initiate a formal investigation of this problem and force Porsche cars of north America to initiate a recall campaign for the safety of the public and for the thousands of owners like myself who have spent 70000 to 90000 on a premium SUV and are left helpless. Thank you for your assistance.

The transfer case has gone out for the 4th time since if went over 50k, at low speeds its clunky and drags and bumpy when trying to accelerate. I found other individuals having the same problem mutli times as myself and this is not cheap to fix. The dealer knows this is a problem but will not help with cost.

Transfer case failure. Care clunks/drags in low gears.

Transfer case fails very often. It causes the vehicle to jerk and unstable during driving. Porsche hasn't addressed this issue even though it is a very common problem on Cayennes.

The Porsche dealer informed me the bumping noise while accelerating is the transfer case. It is a common problem on all 2012 Cayenne cars. The transfer case will make the bumping noise when accelerating. It will eventually slip to the dangerous point. This is when you accelerate into traffic and the transfer case only slips and leaves the sitting in traffic unable to move. The repair is $5000 and replaces the transfer case. The new transfer case corrects the design flaw. The flaw was in the transfer case vents that would allow water to build up in the case. The new case comes with vent tubes installed so the case can vent properly and water doesn't build up in the transfer case fluid. It is a shame that this problem happens between 30,000 and 80,000 miles. If I pay $60, 000 -$100,000 for a car I would expect to get past 100,000 miles before a major repair. Hopefully I don't get killed in traffic when it starts slipping more.

Transfer case failure. There is an acknowledgment by Porsche of an associated defect of the transfer case design and a related workshop bulletin (wb) when replacing the transfer case. Porsche mechanics are instructed to replace a "vent hose" for the transfer case. This newly revised design part number for the revised vent is 958-301-047-10. The reason: the original design for Cayenne 958 Porsche transfer cases had the hose ending on the lower (closer to the ground) side of the transfer case. The new hose ends on the upper (further from the ground) side of the transfer case. Porsche determined that moisture was getting sucked into the cases and causing fluid contamination. Since the transfer case uses a "multiplate wet clutch", moisture could prematurely corrode or allow rust to form, which could cause the clutch to bind and work erratically. These are symptoms described by multiple owners of 958 Cayennes discussed in Porsche forums (e. G. Renntech. Org, rennslist. Com, etc. ). This revised vent developed by Porsche to replace the existing design, should be covered by Porsche. Moreover, owners of 958 Cayennes who have experienced failures of the transfer case and subsequent replacement of the transfer case and the newly designed hose, should be reimbursed for the full cost of the replacement transfer case and the hose. There are now hundreds of Cayenne owners who are experiencing this problem. Moreover, the maintenance schedule does not call for any preventative fluid changes of the transmission oil. This should be revised and recommended servicing should be prescribed (e. G. , every 10,000 miles). The failure of the transfer case could cause vehicles to lurch or react in an erratic or unsafe capacity across the spectrum of operation, including highway speed driving. Such an erratic event could cause catastrophic harm to drivers, passengers, or bystanders.
