Just curious to your driving habits, do you do a great deal of stop and go or city driving?

How about off road?

Do you use carwashes?

Severe cold or hot environment driving conditions?

Towing?

There has to be something unique to your driving style, environment or vehicle to cause so many failures.

Anyone else on their 3rd, 4th or more Transfer Case?

Don’t have the service records on me at the moment, but the failures were at approximately 11k, 28k, 38k and 51k. The car is 3 years old. Gets about 15-20k miles a year. Mostly commuting on the interstate to work and family trips. No trailer pulling. It’s been through an automated car wash only a handful of times. No off-roading. We do live in East Tennessee, so it is hilly, but it only see snow a few times a year and it’s only a couple inches. Temps range from 20-90 here depending on the season, but i wouldn’t call that extreme. I’m one of those **** retentive engineers (LOL) that takes meticulous care of his vehicles and it’s babied for the most part. If I want to punish something on the backroads or the track, that’s what the Cayman is for... If I abused the car or was rough on it, I would expect it, but it’s been nothing but babied and well maintained and I’ve been averaging 10-15k per TC. Only have 10k on my first set of replacement tires and that’s because of a puncture on a trip and I’m still on the original brake pads with quite a bit of life left on them if that speaks to my driving style for the Cayenne. Those TC’s are just junk. Either their fluid is still getting contaminated way too easy or the friction material on the plates isn’t engineered to the proper standards. They need a revised part, not a new vent tube and a fluid change every 10k. That’s just a band-aid on the real problem.

Carl,

i am in Central KY so similar weather.
Sounds like you take very good care of your vehicle.

Regarding your driving style, do ease onto throttle gently and very seldom accelerate rapidly?

Are you the main driver or does your wife drive it also?

I am thinking the harder the acceleration the better as this will lock up clutch quicker vs. being gentle and causing more clutch slippage.

For other failures it maybe due to contamination of fluid but I don’t this applies to your situation.

Comments anyone?

I’m basically the only driver. Wife drives it rarely, since she like to be chauffeured around... I do maintain it very well and take care of it, but it’s still a Porsche, I wouldn’t say it doesn’t still see it’s fair share of acceleration. I don’t drive like grandma, but I also don’t flog it like a track car. Not too hard, not too soft... just right! Lol
