After starting my 2014 Cayman S, the steering wheel is quite difficult to turn when backing out of the garage. I get a vibration and loud clunking. After turning again, both are decreased significantly. On the 3rd turn, the condition disappears, only to return the next time @ start up.

The battery got run down @ the body shop and I got the "Steering Support Limited Drive On" message that I thought this issue was related to. After clearing the message by turning the SW in both directions a few times, I expected the issue to go away as well. It hasn't.

Any ideas?

TIA

This is normal. It is a function of the front suspension geometry. It happens when turning sharply at very slow speeds, both going forward and reverse. What you're feeling (and hearing) is actually the tires skipping on the pavement. This is particularly noticeable on cooler (cold) days. It may be disconcerting, but does no damage.

Thanks for the clarification - I get the same "stuttering" when just starting out, when turning sharply at slow speed, and especially on colder days. Thanks!

Cannot recall this in any other car but good to hear it is not an issue.

Thanks DBH

Honestly it doesn't sound like the same thing. The usual 'acorn effect' due to Ackerman geometry doesn't cause the steering wheel to become harder to turn, it doesn't cause any sort of vibration, and it goes away only after the tires warm up (or the pavement does), not after an arbitrary number of turns.

What's the pavement temperature when you're experiencing this? What tires are you running?

I have to agree with Noah your symptoms do not sound like the " Ackerman Effect ". Vibration and clunking aren't normal IMHO.

I'd suggest 2 things:

- google " Ackerman Effect Porsche "

- take it to your dealer and have them look at it.

Also, you stated your car was in the body shop - was the car involved in an accident involving the front end ?

cold tire scuff is very common with these cars and is not an issue BUT as soon as you start the car up ,even with out moving the car, you should have power steering ......if not there is a problem

Occurs each time at start up regardless of the temp. Only have a couple of hundred miles on it so far but its happened backing out of the garage @ ~70*F or a parking space @ ~90*F.

Tires are Pirelli P-Zeros (220s).

No accident. Was having it wrapped.

Just turn the steering wheel lock to lock before moving the car, and if you have a power steering issue, you'd feel it right there. If you still feel something is wrong, and for no reason (battery fully charged, no pothole hits, no accidents, etc), just take it in. You didn't specify mileage, but most likely still covered under warranty. Good luck.
