I have a new 991S Cab that has a loud clunk when I go over speed bumps. I have had the car in twice, PCNA has gotten involved. They have not been able to fix and and now tell me that it is "normal" in the S models, but doesn't happen in Carreras. Has anyone had a similar problem with a new 991S? What has been done by Porsche? I think they don't know what it is, but it's definitely not acceptable in a $130K car.

 

Hi, i have been over many speed bumps in my 991S (hard top, no sunroof, sport suspension) and not a creak, rattle or clunk.

And I agree, that does not seem normal nor acceptable. Hope you get a better answer than that soon.
