I have a 2003 SE-R Spec-V and I hear the same kind of noise but only once in a great while. It never works when I take it to get serviced of course, but I find it ususally does it when I back up and turn to the right, but not always. It is very unpredictable. Does this sound like your problem? My warranty runs out in less than 500 miles which will be less than 1 week the way I drive so if anyone can give me any suggestions as to what this would be or how to tell the mechanics to fix it, that would be great. Thanks.
