Had mine replaced on Tuesday @ 29k Figured I would have a loaner for atleast a week and a half because of the holiday. Porsche of the Mainline finished the job in 1 day! (had an updated transfer case in stock) A+ service

 

Took my 2017 Macan S into the dealer for its 40K miles service. Told them I was experiencing occasional bucking when accelerating form a stop. SA called me the next day to say I needed brakes and rotors ( I inquired about replacing the pads only, was told the Porsche requires pads and rotors replaced at the same time) and BTW the transfer case that was replaced less than a year ago was now defective and needed to be replaced again.
Memo to Porsche, great driving experience only goes so far, at some point owners will leave if parts are unreliable and fixes have to be fixed. I am waiting breathlessly for my timing cover to start leaking. Having second thoughts about keeping this vehicle long term.

 

I was in the exact same position. My xfer case went at 43k miles I think. But that was replaced under warranty.

Everytime I took my car in, the SA and I would shoot the bull when I went to pick it up about what could happen next. They attempted to isolate the bigger problems to certain years or manf dates or ranges, but never were able to pin it down. While he didn't tell me the exact number, he said they had quite a few xfer cases replaced. It's an easy swap but the part itself is costly. As far as the timing chain cover, he said he's more concerned about that. He went into a few other things they had seen that probably they shouldn't see. He mentioned Porsche had recently authorized new bolts , but it sounded like there was no real definite solution. For the xfer case, they had a customer who was out of warranty but they caught the problem early, so they changed the fluid on it before it got so bad and that cleared things up. So anecdotally, it looked like this was a workaround or some short term thing for the time being.

I drove both Caymans and a 911 I had out of warranty for a long time. But my CPO on the Macan would expire in January. In the end, I could live with everything other than a gamble on a timing chain cover.

 

2017 Macan S 22,800 miles Transfer case replacement today

 

I just got my 2015 Turbo about a month ago. It was showing symptoms of transfer case issues (some hesitation on accel, clunking once in a while). My local dealer got me in quickly and ordered a transfer case before I even dropped the car off. Had it done in under half a day. Symptoms are gone, back to driving smoothly again. I have 48k miles.

 

I too had to have my transfer case replaced on MY 2017 Macan GTS (delivered March 2016). Had the symptoms of a slipping transmission and I was about 1 month past the 4 year warranty and at 37,000 Km - about 24,000 miles.
Told by the dealer - Pfaff Porsche that this was a common issue as water/condensation gets into the transfer case fluid and this causes the case to fail. Luckily after some wrangling by the dealer with Porsche Canada - the case was replaced under warranty.
Must be some type of seal issue - I’ve never driven the GTS thru standing water etc.

 

2017 S transfer case was replaced November 2020 at ~45k miles. Had been exhibiting symptoms for a while. Dealer had my car for several days because they were working on several at once and had to wait for a rack to be available.

 

So I am one of those who had their TC replaced. Typical symptoms. Actually thanx to this forum I was able to diagnose it and have them change it for a new one. I actually already bought the car and drove for a few days and then discovered that after I drive it for a few kms that it's acting up.

Called Techart where I got it from and they said let us drive it again and see. Right away they agreed with me and had the transfer case replaced.

Now I'm thinking, how soon should the oil inside the TC be replaced. What are your guys thoughts?

On Youtube I saw a few interesting videos of mechs who suggested doing it much more frequently then what is recommended.

What have some of you guys done who have had their TC replaced?

Thanx guys.

 

Anyone experience a metallic whirring noise at relatively low speeds (~37mph) and at higher highway speeds? I hear it on smooth roads. A highway feeder with cars around, I can't hear it. But on a nice piece of road, yeah.

New wheels and new tires and new brakes. Still have the noise.

 

Fired up the Macan this morning on my morning drive, and I heard cranking and grinding in low gears and only during acceleration. The wheels didn’t need to be turned or only going in reverse, and something clearly sounded off—almost like a metal pipe was dragging and grinding during acceleration. It came out of nowhere. There was no noticeable sound at speeds above 30-40mph while cruising. I have read this forum enough to know what is happening….

This seems like a textbook case of a transfer case failure, and I have an appointment with the Dealer to confirm it. I am looking for advice….

2015 Macan S (was previously CPO’d) and always serviced at a very reputable Indy shop that saves me at least 25%+ on regular maintenance. My Macan has 45K miles on it, and has been extremely well maintained. The “extended” 7 year warranty on the transfer case expired in 2021, and I have failed in the past when requesting goodwill service/coverage on fluky things. Oddly enough, the dealer said they had never changed one on an out of warranty vehicle so didn’t have a price estimate top of mind. I find that hard to believe, and not looking forward to seeing a repair quote once they diagnose.

I plan on pressing the service manager hard about requesting a goodwill repair. They are clearly defective regardless of time and/or mileage. Does anyone have tips or tricks on what I can do to make my case? There is almost no information about Porsche Goodwill. (I had a fluky rear suspension issue one month out of warranty denied by a goodwill request, and ended up replacing the rear shocks at an Indy.)

If the dealer comes back with an outrageous quote and no PCNA goodwill coverage, I might *** be done with the brand. The other option is take the job to an Indy, and I will again be on my toes waiting to see a quote for that service. I am expecting a quote in the $3,500 range, but won’t be surprised if I am way off too.

 

I can tell you now you are in for a **** of a shock DOUBLE IT.

 

A Porsche remanufactured Transfer Case is $3059 from Suncoast Porsche. An indie mechanic should be able to swap it without too much problem, it is just bolted to the tail of the transmission. I believe it can be swapped with the engine and transmission remaining in the vehicle.

As an FYI, Porsche (actually Magna) has revised the unit a few times, even after the "fixed" version (rev A, and AX) of March 2018. The Transfer Case in my 2019, built Dec 2018, is Rev = D.

 

Another TC replaced here. Macan GTS MY17, 6 years old, 45K miles. Covered by extended TC warranty. Also got an oil leak repaired, not covered by warranty.

 

I have noticed something funny: after the TC was replaced, I feel that the car is a little less lively than before, and fuel consumption has gone down by 3-4 liters per 100 km. Well, I won’t complain given current gas prices…

 

Had my TC replaced last week on 2018 Macan S with 22,000 miles. Service Advisor said this is a one time replacement by Porsche and there was no revision to the part. There has to be something that was new and improved or modified/updated?

 

Your Service Advisor has no clue...the Transfer Case has been revised a few times since March 2018 when it was revised to fix the original design issue.

 

Very glad to hear it is revised. That was the back and forth the SA and I were having. Not the greatest Porsche dealer and their personnel are clearly an issue.

 

I had ours go at 60k about a month or so after we bought it. Luckily, we had gotten the car with cpo and they were quick to rectify it.

 

2017 base macan
Original Transfer case replaced at 50k miles, 4 years 4 months. Had been acting up at least 5k miles. Stiff and jerky at wheel lock; jerky at very low speeds. Replaced under pcna transfer case warranty extension

Transfer case 2 failed less than 6 weeks with 2k miles. Car went in to safe mode with warning lights. Had an X part number. Replaced with transfer case 3 under warranty extension, case 3 has an X part number

Transfer case 3 being replaced now 8 months/8k miles later, making 3 replacements in less than a year. Again under special warranty extension. Car at dealer so don’t know part number.

Anyone else on their 4th (or more) transfer case?

I now have zero confidence in these X part numbers. Refurbished, already failed units??
Clearly this transfer case issue is not resolved and the replacement parts I’ve been getting are not working out.

 

TC gone at 50,000 miles. I'm negotiating with the nearest dealer with a chance that Porsche might replace the box even though it's just outside the 7 year extension period. It would be a once off, so if there's any chance of having the same experience as F....a above, with 4 replacements in quick time, only a madman would follow on, knowing you'd have to pay out each time because Porsche have disowned the problem.

From what I've read about X cases [rebuilt in Mexico I think], I'm not encouraged and will seriously consider selling the car if that's what is fitted.

It's been a horribly wet year here and I suspect that's played its part in the failure. A breather would help but as with so much else on these cars, there's no certainty and it's up to owners collectively to figure this stuff out to the best of their ability.

The other option might be to have the case rebuilt locally by an expert but first, find your expert. The Porsche price of $3,000 or so for a re-built case is quite outrageous when the actual cost might be $750 or less.

Hope it works out for you. 3 TC failures in 9 months was too much for me so I sold the macan last week. Was told they used the same part number for replacement 3 as they used for replacements 1 and 2. So I concluded that the risk of future failures remains very high

 

50 pages on this one now. I think I remember a post on the topic of rebuilding a TC. Can anyone direct me to it please?

My 2019 Macan, built Dec 2018, has a Rev D Transfer Case.

Yes, an "X" suffix means remanufactured.

 

Looking at the "Verification transfer case upgrade" thread, there weren't any post March 2018 complaints about failure in that thread. Does this mean that there haven't been any failures with the modified case or that they're lost somewhere in the large volume of comments this topic has generated?

If post March 2018 cases have failed, are they replaced with the improved materials 95B.341.010.A with an X or if a post 2018 fails do you get a std. 95B.341.010 X?

I'd happily pay for an "A" if they were available and if they're actually lasting for a reasonable period of time.

At some point Porsche will surely drop the replacement policy that started at 7 years and is now rumoured to be 10 years. I suspect there will be a rush for the door to sell off a large number of cars that could need a replacement case every 20k miles [or maybe less] if that comes at full price.

I took possession of my brand new 2015 Macan S in September of 2014. I had been active on this forum for a while but especially during Covid didn't drive the car much, and didn't participate on the forum. Now of course I'm having transfer case issues and I'm almost a year out of the extended 7-year transfer case warranty, and have around 67k miles on the car. I had the car in for an oil change at the Porsche dealer a little before the warranty ended, and they didn't mention anything to me about the transfer case. Has anyone had any luck getting some love from Porsche after the warranty expired? I'm about the sell this car as I had planned to hang on to it for at least 10-15 years, but if a major component can fail after 67k miles and the manufacturer doesn't think that's a problem, then I'm done with Porsche for good.

 

@IvanC, was you transfer case ever serviced, meaning, was the oil changed at some point, or using original oil from 2014?

 

I agree. I think that knowing the universal issues with transfer case, that oil should be changed more frequently, like every 40K miles maximum.

My Macan is almost as old as yours. I took delivery on Nov 2014. I changed the TC oil for the first time about 3 months ago for the Porsche TC oil. Then, changed it again a couple of weeks ago because I wanted to move to Motul oil. Luckily no issues for me. I’ll be changing that oil going forward every 20-40K miles.

 

My original transfer case was replaced yesterday under warranty. '18 base w/ 18k miles.

Has made a very noticeable improvement in take-off performance and smoothness from a stop.

 

Adding to this thread as it's one of the longer ones on transfer case issues.

My 2017 Macan Turbo just had its transfer case replaced by Porsche of Bellevue with just under 48K miles on the clock. Never tracked, never offroad. Shuddering while backing up was the first symptom and that started maybe 3-4,000 miles ago. It was very subtle at first and only in reverse. Maybe 1000 miles ago it started shuddering under acceleration in 1st/2nd gear. Porsche of Bellevue service was great. I couldn't be happier with their handling of the situation.
