I wonder anyone in this thread has did problem before, everytime i hit a bump i will hear that noise, like some kind of metal that didn't tight it up really good. But when i check my trunk there wasn't anything.

I remember one time i took that piece of plastic, that for the convertable to lay down. When i have subwoofer in my car, but now i put it back, i lost a lot of nut. but i didn't think plastic piece would make that metal noise.

Help me out please, that shit sound really bad.

 

Are you sure your spare tire is screwed in all the way. It took me a week to figure out that my trunk noise was coming from a loose spare tire.

 

i have that noise too. don't know what it is.

 

Sometimes if you have anything metal in the compartment right above the center glove box thing it will make that sound. I had a couple tools in there and thought it was something in the trunk. If thats not the case, then the spare time thing is a good idea.

 

I rememer I was test driving a red s2000 and it had an amp in it and evry bump or whatever it made some weird sound from the trunk...The dealer was like yeh no biggie well fix it but I was like whatever

 

Definitely check the spare tire tie-down (like alexz said). When it's loose, it can make an awful racket!

 

i took a spare tire and everything out of the trunk and it stills make that noise

 

Damn...I was gonna vote for the spare tire...

 

i took everything out, and it still making that noise.

 

Look for something broken in the exhaust or suspension.
