My Accord EX 2004 developed the same set of rattles within 6 months
after purchasing. I put a lot of miles on my car (up to 37,000 after
13 months) and the rattle does not go away. The dealer could do
nothing. I learned to turn up the radio. The rattles and the
humongous posts on both side of the windshield are my only complaints
with my Honda.
