im pretty sure someone posted a while back that the issue was a free metal ball like piece within the rear seat belt assembly and the fix by the dealer was to replace with new one... and another posted that it was the trunk light wire from what i can remember.

On further research it seems that the wire was an issue for some but didnt work for everyone...

 

^^ I was aware of those two possibilities, I tapped the seatbelt assemblys and wrapped the assemblys in dynomat to be sure, i also made sure the trunk light wire was not the source. Believe me I went through it checking all TSB possibilities. Im going to stuff a bunch of foam in the crevices around the wheel well and behind the rear/right of the rear deck area to try and quiet the noise. Im convinced (but not totally sure) its a loose spot weld or something in the hollow space behind the sheet metal... any imput or thoughts are appreciated.. oh yea, when cold its the loudest, when hot its hardly noticable..im reaching the end of my search for it but I would love to find the root cause..

 

my car developed an intermittent rattle. after a bit of knocking around, i gently kicked the right tailpipe and there it was. the exhaust isn't fastened well enough somewhere. i will update when i get that resolved.

 

rattle here as well, i thought it was coming from the exhaust until i got up under there and shook everything. its most likely something in the rear decklid. it will happen usually when im sitting still in drive. it doesnt do it when im moving. when the engine is revving down it happens as well. its definately some sort of frequency related issue
