Hi- I am noticing the same creaking sound coming from the rear of the car at low speeds and/or bumps (when it's quiet). Reading through the thread it seems that it's one of those annoying things I might have to put up with but not necessarily anything to worry about mechanically. Would you agree, or is it going to be a big expense down the line with changing the suspension? Is this sort of thing covered by warranty or do they put it down to wear and tear?
