Before I run to the dealer and seek a warranty fix -- got a 2010 Cayman S with about 17k miles on it. VERY easy life so far. Lightly optioned - does have the 19" combo. I've got a very persistent rattle back behind the passenger compartment somewhere. Relatively low frequency (as rattles go) - just about any bump the rear suspension hits generates the noise. Sounds like something is actually loose --- anyone had anything similar? Driving me crazy - and I don't see anything obvious under the hatch. Have done a good bit of checking/shaking/etc. to try and replicate it when the car's parked - all with no luck. Haven't been under the car yet. Placing rear spoiler in up position has no effect.

 

if you go to Planet9 there is are several discussions about this!

 

Eventually discovered that - and at the Cayman Registry. Added some felt in the right spot and adjusted the rear hatch stops -- quiet as a mouse. Well, more like a cat stalking a really quiet mouse.

 

I just backed my rear hatch stops out 1 turn and mine stopped creaking.

 

Oh man.....glad I ran across this! I am going through the same thing with 2010 Cayman S, driving me crazy!!!! So it is actually the rear hatch/stops that need to be adjusted?

 

I believe that with time, the rubber compresses and loses some of its elasticity, sort of like your running shoes after you've ran several hundred miles in them. Backing them out a little compensates for that. Some people add felt as an added measure, mine didn't require it. Best of luck.

 

Good to know! I really thought I had some suspension issues to work out.....but it has been so cold here, I was waiting until Spring to address it. Hopefully this should take care of it! Thanks again!

 

Can someone take a picture of the area where the fix is needed.
Thanks
