Mine just feels like it has a tight diff or different turning arcs for the front wheels when using a lot of lock - particularly when going right out of a junction first thing in the morning. The front tyres seem to skip or hop to get back in sync with each other. Do they all do this? It can make for jerky and mechanically unsympathetic quick exits from junctions. Cheers
Does your front end hop and skip on tight turns?

Sorry, thanks, just joined as I was looking at changing my GLC back to Macan ( had a turbo previously) but really can’t stand that skip sensation so will have to keep looking for a better alternative
Google Ackerman effect. Lots of info regarding this on the Internet, which should give you some pretty good clues as to how you can avoid it. If I recall correctly, Corvettes with wide tires also suffer from it too.

Hi Everyone
I'm living in Dublin in Ireland and have a 2017 Macan S Diesel which is by faaaaaar the best car I have ever had - and I have had a few !!
One thing that is causing some concern is that when reversing, or turning very slowly, a 'grinding' noise can be heard. It is like a shuddering, which does not occur at higher speeds i.e. when driving normally. Someone said it may be the wide tyres (Pirelli P Zeros)
Also, recently, and after just replacing the back tyres, there is another disconcerting clicking when changing up thru the gears, when giving it a little wellie. I tried this under the changes to the Chassis (sport and sport extra) but it really only changed it a little. I wonder if it might be a problem, or perhaps (no that I think of it) a little dirty fuel - what they used call 'pinking'
All advice gratefully received
Thanks

Not sure - will try
I’ve noticed what I instinctively can describe as a tire scrub even though I know there is already a formal definition of tire scrub. Let me describe.
This occurs immediately after I start moving the car while turning. Like when I am backing or forwarding out of a parking space and making a 90 deg turn at the same time. There is a short, staccato grunt which can be heard and felt, coming from the tire(s). If there is a painted parking line that a tire crosses, the grunt/scrub happens even more obviously. It only happens once per incident.
Anyone else experience this? I am assuming it has to do with the wide tires doing a very short skip (scrubbing) on the ground to relieve tension caused by the car moving in a direction different than the tire direction for a brief moment. (I have 21” wheels, so 265/295 tire widths).

I had this & it went away when I got new Michelin tires.
It felt as if coming from the rear but must have been coming from the fronts.

Yup I did search, and happened to find one mildly related topic; thus I posted a new thread. Not sure if people need to declare this lest they get the inevitable chastisement.
Anyway, thanks for merging me into this thread, it’s exactly what I was looking for.
The dealer just replaced my transfer case after determining the above issue was the TC. This did not fix the issue. Turning into the driveway last evening the safe issue happened again. Has anyone had this issue?
This is my second Macan and the 2019 model had no issues.

I created an account to comment on this!!
I put my 2022 macan s in the shop after 4000 miles after the same issue you are having. Before I left, I test drove with the lead technician. I demoed by turning left to a parking spot and after the thump, the technician went “yup”. He said it was more “profound” in the 2022 model year than others. It apparently is not an issue… they said they won’t be doing anything on it but hopefully it gets reported to Porsche hq and have this issue resolved!!! I wonderwhat they will tell me on Monday regarding this issue.

This happens on our 2022 base as well at low speeds when turning into parking spots usually. I figured that it was normal and had something to do with torque transfer/anti slip/automatic braking on the all wheel drive system. I’m usually taking a very sharp turn into a parking spot and there is often loose gravel or debris in parking spots so I haven’t worried about it much. I’d be interested to hear if Porsche figures out how to improve this on the OP’s Macan.
Ackerman angle. Google it. Search. Its going to get worse in cold weather if you have summer tires.

Mine does the same thing. Apparently Porsche is looking into it. You can try disconnecting the plug on the transfer box and see if this problem goes away.
It's funny that Porsche claims "This behavior is currently a normal operating characteristic of the drivetrain and is under investigation."
If it's "normal" then why bother with the investigation.

I've experienced something similar in my 22 GTS. Its happened on 3 occasions making a left turn into a parking spot. it feels like something with the power steering. I don't have PS+ so the steering is quite heavy and on those occasions it was like a PS+ function kicked in temporarily with a thump with the steering becoming noticeably lighter for a fraction of a second just before full lock. It doesn't happen all the time and I'm not too worried about it at this point but shall monitor it.
