Car pulling to the right

[eprokos]

Hi, I have a macan ev 4s with 6000km, PASM, 20inch wheels and 4 wheel steering
While I was doing a parking maneuver with around 10km/h, I accidentally hit at the curb with the right front wheel. I heard a loud metallic noise from that wheel.
At that time the car had just 1400km
I thought I damaged the rims but actually nothing happened, not even a scratch.
That specific week I stepped on a screw and right front tyre was damaged so I changed only that (I am repeating only 1400km)
When I went in the highway after couple months at around 4000km the car starting pulling at the right direction (I did not notice it while driving at the city)
In order to keep it straight I should have the steering wheel at 2degrees left
First visit at the dealership they told me that right front tyre had 5mm of tread while front left 4mm and that was the problem, that I changed only one tyre.
Second visit they told me that they had to do wheel alignment, which they did. They found differences both front and back!! (I have also rear wheel steering) and they fixed...
Of course it was not fixed
Third visit they tried again wheel alignment and told me that something must be faulty.
Their decision is first to change the two front right control arms because most probably they are bent (and they blame this parking maneuver, I told them that I did that to help on the diagnosis)
If the problem persists they will go deeper to the subframe(????!!!!!!)

Can this actually happen to such an expensive car so easily? Of course they told me that is out of guarantee.

Anyone had same experience?

thank you

What MY? I had problems with alignment going off every now and then and there are some new guidelines for torque required to tighten screws. Not all dealers know this apparently but in cars with such problems the HQ recommends using 20-40NM more than the original spec which was 80NM if I remeber (seems low for such weight). It may require replacing these bolts. I think in my case it also started witth VERY gentle curb overpass and ever since it’s was not possible to permanently fix the suspension. It’s supposed to be fixed in MY2026 with slightly different suspension tuning (info i got from my SA) and the fix is applying this to MY2024/2025. Tell them to contact the HQ. I suspect once they permanently fix this, there will be a bulletin for this.

Shall be MY205. I bought it 11/2025

In the wheel alignment they found in caster 01.07 degrees difference in the front wheels which in the report they fixed..

Does it pull just when accrlerating or breaking?
Does it pull on all height levels in case you have air suspension?

I have airsuspension, yes in all levels

No difference or pulling while braking

Mainly in the highway just coasting

I would go back and ask for the re-alignment.
They may have corrected it but once you left the shop something moved.
There are ways to check what can cause this - they put markings on bolts and parts to see what causes this. There is no way around it just go back to the dealer and report it untill they fix it.

so you dont agree to change the control arms? it is not that they found them faulty, but they said "hmmm lets change and see if they are bent or not"
if not we have to go deeper to the subframe

shouldn't there be a way to verify before changing?!

I think if anything was bent or the subframe was misaligned you would have seen it in the suspension alignment which would not be possible to set with proper parameters. Ask for the printout and run it through chatgpt, you'd be surprised by the insight.

You didn't mention it, but was the front tires replaced after noticing the difference in wear? Do you know if they swapped front wheels/tires left and right to see if the pull follows? Did they check for rear tire wear differences?

A dragging brake perhaps?

will do it and share in a bit here

no they did not
when I told them that I am willing to put 2 new front tyres but only if they tell me that this will solve the problem, they told me to take it again for 2nd time.

they thought about swapping but I dont have any knowledge if they did

for rear tyre again I have no idea...

I was told at the 3rd visit that in the 2nd visit the outsource garage they took the car (cause their wheel alignment machine is broken..) told them that he will try to bring the car to alignment cause he saw bent stuff.. actually I dont believe them, I think is just an excuse cause I was misinformed during the 2nd visit that the car if fixed!!

actually I have lost trust and unfortunately it is the only official repair shop

Welcome to the club, many authorized shops are lazy and incompetent and it’s surprising it seems to be a global issue in many countries.
Press them for detailed data - what was bent, how was the alignment before and after - let them show you the data and not some BS explanation. Run the data through chatgpt and ask followup questions. This is the only way to get anything done if you dont trust the shop and have no other option.

I'm almost certain there were couple of posts here concerning that matter, Tomek @TomekGnomek you were the one?It was some time ago so it's quite hard to remember if it was only you or also someone else as well.As far as I recall the issue was discussed quite extensively and the thread was alive and hot for some time.I personally know @eprokos very well IRL and frankly what he was told by the service center (I bought my 4S from the same dealership as well) it was at least alarming if it wasn't just BS due to their ignorance and incapability to address things the right way as they should.They told him it's very likely the car was probably severely damaged and most likely something is bent because of the curb impact and the same could also happen because of just a pothole as the car is very heavy!!!How it's possible such a car designed to also be safely driven off-road to be so fragile (even though its off-road capabilities must be considered as "mild to medium" and be cautiously driven during such conditions)?If a curb contact with just 10Km/hour can cause such a damage, hitting an off-road pothole or a rock will cause what? Break the car in half maybe or what??

Yes, I had these problems and they are not as of yet resolved. My car has had the alignment done 8 times over the last year and each time after 200-500km the problem comes back - it starts pulling to the left, at first only on acceleration and in lower suspension setting, after a while it pulls all the time.

I just don't care at this point, I'm set to replace this car (waiting for the longer GTS test drive in a week to decide between the GTS and Taycan CT) and adjust the alignment every month or two so it drives reasonably well.

I can confirm this is a wider problem and Porsche knows about it. My dealer is in contact with the HQ, they have tried many different procedures and so far it looks to me like a structural problem - once you adjust the subframe (manually during alignment or perhaps by hitting the pothole or a curb) it's difficult to fix it permanently. They told me cars produced after a certain date have the suspension fixed in a slightly different way (don't ask me how, all I know is the torque spec is different but they replaced the bolts as well saying they are different). On top of it it seems it can be somehow connected to air suspension height sensors calibration and one engine producing slightly different torque (at least these are the issues they were looking into based on what the HQ told them).

I'm not saying it's the OPs problem but seems connected.

This is something you have to press the dealer hard to have it fixed - at first they will claim they don't see the problem, tell you "it's the road or tires", "you had to hit a pothole", "we don't know if you haven't driven it on track or offroad" and in my case only after they marked the bolts and saw that something is in fact strangely off they started taking it seriously.

amazing what you are describing!!

amazing!! it is like my case
