Go to a different dealer?
If Porsche NA is willing to pay why wouldn't any other dealer be able to help you.

Maybe they don't want the "reduced fee work" if they're swamped with far more lucrative services that take up their service bay and technician times.

THIS!

I was not aware of the transfer case issue at time, however the drive was not smooth in local roads, I thought it is a feature as these cars are designed for highway, didn't push too much for service manager to investigate.

I believe the diesel version used the Audi Quattro four wheel drive system, rather than the Porsche four wheel drive system.

Steve, I wanted to learn more about how you managed to get this accomplished as I am too now having this problem and this after being 2 months out of the extended warranty and having only 38K miles on my vehicle.
Would you be up for sharing how you succeeded in getting this replacement covered outside of warranty?
Thank you
Bob

Yah, I have been to two different dealers and contacted Porsche North America. They all said SORRY no mass.

Just joining the transfer case replacement club here. I just picked up a 2018 CPO Cayenne Base about 3 weeks ago with 33k miles on it. During the purchase process and test drive, I did not notice the hesitation and it drove really well. I actually liked it better than the 2020 that I was comparing it with (especially for $15k less). I did notice the tires were going to need replacing soon but they had enough tread to pass the CPO inspection apparently. Well, once I got the car home I looked closer at the tires, and they were just over the 6 year mark and were supposed to be replaced. Thankfully the dealership had no issues covering the tires (though one has to wonder about other parts of the inspection that passed also since this was a clear checklist item on the CPO inspection).

Back to the transfer case, once I was driving home in stop and go traffic allowing the car to warm up fully, unlike the test drive, I started noticing some annoying behavior in 2/3 gear. Some stuttering/hesitation. It wasn't super obvious but I immediately looked up the transfer case symptoms when I got home. Sure enough, I pretty much new that was the issue. Took it to the dealership that was closer to me and they confirmed it. It was replaced. So now I have a nice fresh transfer case and new rubber on the wheels. Hopefully she's good now! Anyways, I'm happy with how both dealerships service centers handled it. There was no pushback on either the tires or transfer case. The thing that is a bit annoying is that the inspection doesn't seem to be very effective.

I second that with almost identical experience. It was a bit disappointing since I blindly trusted everything to have been in near perfect condition being a CPO and turned out not to be the case.

This has probably been asked but... If you suspect your transfer case is going, but you still have warranty left, is it better to wait closer to the end of the warranty? Does waiting mean other parts may be damaged due to the transfer case?

My 2018 Cayenne has a warranty until Feb 2025. Debating getting it diagnosed/replaced now, or waiting.

I had thought the same since I just started my 2 year of CPO warranty time. But I wouldn't want the thing to fully fail an strand me somewhere. Hopefully the replacement part has the issue solved. I think there is detailed discussion of the replacement part earlier in this thread as some people have gone through multiple transfer cases.

Simeon

Fix it now. Why suffer through the annoying symptoms.

I created a thread outside of this since I may the first of eventually many cases that fall outside of the warranty window. Are people DIY'ing their transfer case swaps now? I changed with Ravenol fluid on my E-Hybrid, after feeling a very very subtle vibration with turns at full lock. Other than that, car seems to operate perfectly fine. Am I overthinking it, so are these early signs?

Are you certain your turns at full lock were not just tire chatter? That happens when wider tires are asked to make turns tighter than their width will allow. It used to happen on my Corvette all the time. Even if it was only tire chatter, you still did a good thing with the t/c fluid change.

Malmenator

So I actually just learned that the E-Hybrid transfer case apparently is of a different model than other Cayenne models, in that I wasn't supposed to use the Ravenol DTF-1 for it, but I was supposed to use 75w-90 gear oil. I'll be buying two bottles: 1 to flush, 1 to fill. Hopefully this is all I need to do!
