there's some nut/bolt that's loose. everytime i drive the car over uneven road you'd hear the damn ringing sound from behind the passenger side. any idea what's loose? i've removed everything that's loose from the car, and still it rings...

 

seatbelt?

 

My passenger seat chatters on bumpy roads and the secret compartment cover can too.

 

Seatbelt buckle?

 

I pulled the spare tire out and when I put it back in I didnt tighten it all the way and it took me a week to find that rattle. It sounde like something in the top compartment, but no it was the tire bolt rattling...

 

Agreed!!!! Check that sucker. Its happened to other owners. I have my spare held in by blocks due to it having an amp in the middle.

 

I had one of the nuts that attach the third brake light to the trunk back off and roll around in the webbing structure of the bottom side of the trunk lid. Took a while to figure it out, but if you open the trunk and move the lid up and down quickly you should hear it rattle around if it's the case for you.
Good Luck!

 

I've noticed the passenger seatbelt rattle against the door as well - is this it mingster? There needs to be a cover or something for when not in use from rick...

 

I've noticed the same thing recently. It's not so much of a rattle as it is a "ringing" as mingster described. It sounds like there are a couple coins resting on top of each other back there. I've been meaning to check the spare, but haven't taken the time yet since I've been too busy trying to find out how to stop my rear view mirror from vibrating.

 

the seatbelt rattles against the passenger door so i ended up putting a honda shoulder pad on that side. problem fixed
