I found it odd that 2 advisors at the dealership said that the transfer case issue was more prevalent in Cayennes and that they had not seen it very often in Macans. Yet so many people on this forum obviously have had the problem.

Just a simple road test with both SA’s and they were able to diagnose it right away because it is so noticeable.

I think SAs get taught that line at training, “we see that issue on model X , but not your model” to make you feel better. I feel the ooposite way however. I replaced a TC on our Cayenne and when the SA conceeded that it was a common problem but usually fixed with the new part, it made me feel better because it gave me confidence they knew what they were doing (of note, TC replaced at 35k miles, no further issues through selling Cayenne at 85k miles).

My AS was another experience altogether. I got “we never see AS issues in Cayennes, only Panameras”. At that point I felt like the lucky “winner”and worried that I would be the experiment for the tech team. 2 years later, and thousands of $$ worth of parts, some paid for by Porsche and some by me, the problem persisted and it was time to move on. I was smitten by the Macan PDK so I gave the brand another shot however

I feel like the denial by some dealers and Porsche corporate that TC issues are a real thing in Macans is just making owners angry and making them less likely to buy another Porsche or recommend to friends that they should get into the brand. It also makes us current owners nervous about keeping our vehicles after the warranty expires even if overall reliability data (which Porsche does not share) indicates no reason to worry. The problem is that stats and experiences are different things and being the statistic really sucks out the joy of ownership.

So far I love our Macan S, 24,000 trouble free miles and hoping for many more. Best of luck to those dealing with TC issues currently.

That's terrible at such a low mileage, but it's better to show up early than out of warranty. So many transfer cases were replaced, Porsche should step up and issue a TSB for this. That's the right thing to do. This is not a Yugo.

I think a recall will depend on the % of cars affected, especially this is not a safety issue.

Issuing a TSB is not a recall. Upon searching, a TSB was issued on 3/3/18 by Porsche regarding the transfer case/tranny.

Does that mean even if my transfer case goes out after the factory warranty period it is still covered?

No it does not

Hope for Porsche’s goodwill.

Porsche will likely to goodwill a repair when the vehicle is regularly serviced at the dealership from my experience. One of the front caliper on my 911 went bad well past warranty 3 years ago and my service advisor went to bat for me and got Porsche to paid for the repair.

I am finally getting my mew transfer case this coming Thursday. Had to wait a month. Service manager had 3 ordered, and apparently there was no stock in North America a month ago when I went in for my 3 year service. My guess is Porsche will honour this issue well into the future, given the known issues.

Has become seriously annoying in the summer. As soon as the oil temp gets to 100C, it bucks like a Bronco. Finally just pulled the cable and turned it into 2WD for the moment.

So there's a way to "turn off" the AWD? Leave it to Macanuck to figure it out

Assuming it makes the Macan RWD, sounds like it could be fun! I'm thinking about how you can turn off the AWD in the new M5 and E63 (aka "drift mode").

OK, the first person to post video drifting their Macan wins!

On a more serious note I'm beginning to feel a new transfer case in my future...

They will pull the cable to electronically disconnect the transfer case. But it makes it a FWD Macan. At least that's what I recall being told.

That’s a bummer.

 

[wwahl]

If this TC need occurs couldn't you go to the adjustment and turn off the rear wheel bias?

 

[grim]

Anyone know where we can obtain the TSB’s?

Some maybe at renntech.org

That is unfortunately correct. The transfer case hangs off the rear of the PDK and turns the driveshaft for the rear wheels. It is what controls the transfer of power to the rear wheels. Disconnect the control unit and no power goes to the rear.

Thank you for the details, makes sense.

I tried google search and the best I got was from a site called truedelta.
This site allowed a few free accesses and this is from a copy-and-paste on the relevant TSB [just a snippet]:

NHTSA ID: 10130120
TSB ID: 122-L7P4X-03

The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state. power transmission between the front and rear axle is controlled electronically via the "all-wheel drive ser..

You can have a lot of fun searching either/both NHTSA IS or/and TSB ID.
