2020 Cayenne Steering Judder

Hi all,

New to Cayenne ownership and recently picked up a 2020 Cayenne Coupe that has 22 inch wheels and Pirelli P Zero tyres. I’ve noticed that when turning at slow speed with some acceleration there is a horrible judder on the front and it almost bounces round the corner. For instance pulling out at a junction turning left or right 90 degrees or parking. It just doesn’t feel right but I’ve phoned Porsche and they have assured me it’s the Ackermann effect and it’s due to the cold weather. If I turn without any acceleration there is none of this.

I’ve seen bits on this previously but nothing specific to this model of Cayenne. I’m hoping some people on here may have experiences to share to put my mind at rest.

Thanks,

Mike
 
I do not have experience of the Cayenne, but the Ackermann effect is pretty common, particularly in winter, when tyre treads are less flexible. I have experienced it on 911s and RS4.

Hopefully you will get some Cayenne feedback, but in the meantime it would be worth searching the forums (Rennlist is worth a look), as there is quite a lot of coverage of the Ackermann effect.
 
Yes, I’ve had a number of Cayennes over the years and ‘they all do that, sir’. As do the 911’s. Just take it gentle on full lock.
 
Thanks both for the reply. Temperature was 10 degrees yesterday and had absolutely no issues. Something to get used to then!
