A few weeks ago i brought my Accord for the 10,000km service and brought up the issue of the rattles to the service department. They also applied some foam insuation under the rear parcel but it hasn't helped. It still rattles like hell! It seems that there definition of rattle compared to mine is very different. I was pretty disappointed that they did not manage to fix the problem. looks like I might have to try my luck with another dealer and see how I go.
