When accelerating from a stop the car skips/shutters. This generally occurs gears 2-3. This problem has placed me in danger when trying to accelerate while making left hand turns.

- Collierville, TN, USA

The contact owns a 2014 Porsche Cayenne. The contact stated that while driving at various speeds, a rattling noise occurred before the vehicle loss power and stalled. During the failure, the check engine warning light had illuminated. The vehicle was taken to the local dealer Porsche of new orleans located at 3700 N causeway blvd, metairie, la 70002 who replaced the transmission transfer gear. Approximately 20,000 miles later the failure recurred and the contact was informed that the transfer gear was faulty and needed to be replaced a second time. In addition, the speed sensors in all four wheels were faulty causing the vehicle to randomly slow down and not accelerate. The sensors were replaced and the failure was remedied. The manufacturer was notified of the failures but no assistance was offered. The failure mileage was 12,000.

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.

When the shift gear is moved from drive mode to park mode - I was hear reasonably loud clicking noise. Same way moving from park to neutral or drive the sound reoccurs.

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.

When accelerating from a stop gears seems to be missing and jumpy between 2-5 gears, like shudders on gears. I read that it's common problem with Cayenne. This needs to be addressed by Porsche as it is very costly. Vehicle only have 21,000 miles.

- San Jose, CA, USA

While accelerating transmission shifting from 2 to 5 gear, it shudders and power lurches. Same while making turn at stop sign from stop to accelerate at city street power lurches. Possible to cause T bone accident. High chances of complete power loss due to transmission failure due to faulty tranfer case resulting in catastrophic accident. Ask Porsche to replace tranfer case with new designed tranfer case.

Common problem, the tranfer case breaks down causing loss of control while driving. As a result of the problem the vehicle can lurch forward and also fail to accelerate causing safety issues.

- La Mesa, CA, USA

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.

- Santa Rosa, CA, USA

Rumbling noises in drivetrain, transfer case bad

- Brentwood, TN, USA

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?

- Brooklyn, NY, USA

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.

- Melbourne Beach, FL, USA

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.

I'm in a middle of the street to take a left to another street in ft hood tx and the car sounds like something its lock on the transfer case and dont wanna accelerate

- Ft.Hood, TX, USA

The contact owns a 2014 Porsche Cayenne. While driving approximately 40 mph, the transfer case slipped. Porsche of new orleans (3700 N causeway boulevard, metairie, Louisiana 70002, (504) 832-2112) was made aware of the failure and diagnosed that the transfer case within the transmission needed to be replaced. In addition, the fuel gauge sensor incorrectly registered the fuel tank as full. Upon a diagnostic assessment, the diagnostic trouble code confirmed the pretense of a faulty fuel gauge module. The vehicle was not repaired. The manufacturer was made aware of the failures. The failure mileage was approximately 77,000. The VIN was not available.

- Harvey, LA, USA

Car rattles and shakes significantly (especially the rear wheels) during acceleration. Took the car to dealer informed me that it is the 'transfer box' that has failed and it is a known problem with this car. The issue is so common that Porsche does not have parts available and they are on back order. The wait for the parts to arrive could be in months. This should be a recall.
