I've had my CX-5 since 8/12 and about 6 weeks ago the rattles started. I have identified at least two. The first and loudest comes from just under center dashboard speaker. As described in above threads it sounds like a bouncing coin or like a loose washer rattling. It is intermittent and comes mostly on rougher roads. I took it in and they couldn't reproduce the sound. They ended up tightening some screws around the doors, but this did nothing for the rattle. I notice that if I press my hand on the speaker and the dash area just beyond it the rattle goes away, so it is definitely a local problem there. There is a U-tube video of a rattle being repaired at just this location, but no explanation. The other rattle is hard to identify. I believe it is coming from the passenger seat sun visor because when I push my hand on the visor it briefly stops, but it's not consistent. I am going to a clinic for new CX-5 owners and will bring up these issues so I can update whatever happens there.
