Don't know if this is common among Cayman S owners but my car's back suspension squeaks when passing over a bumb or a speed limiter. Car is from 2006, has 25.000 kms. Someone has had the same problem and can it be solved under warranty? Thx - German
It likely the rear hatch that's causing the sound rather than the suspension. I heard this a few moments after taken delivery! There is a weight in the hatch as well as rubber stops that result in the problem. My dealer installed a fix for the hatch and it did alleviate the problem.
Glad they could fix it. It's a very common problem on the 06 Caymans. When I first heard the "thunk" I also thought it was a spring/shock hitting bottom.
