My 01 SSEi is very quiet although once in a while I hear a rattle/squeek. I once thought it was coming from the rt. upper side of the dash. Then I found it was the do-everything inside rear view mirror. The two halves rub against each other and on cold mornings it makes intermittent noise. If I press on the two halves I can make the sound go away. My plan, if I can ever get to it, is to remove the front side and apply a small bead of black silicone sealant around the edge, then press the two halves back together. That should do it.
