In my case all I have to do is put a new sub underneath the seat and I’ll be fine

Rattles and clunks are elusive on a good day. Given that it is a 2008, have you checked the muffler, the hanger, and the grabbed that assembly to see if you can duplicate the sound? I got tapped in the back and developed a rattle that then allowed the muffler to rotate such that the exhaust tip came up into the plastic and melted a perfect cutout like it was a factory feature. I replaced the muffler because the "tap" in the back by a car was enough to dislodge the mounting.

I'm back.... still no solution...

I have a 2008 Cabriolet Convertible with 48K miles.
For the past 18 months there has been a rattle/clink the seems to come from something the chassis mountings as a possibility.
I have had it check out buy the dealership twice and an independent shop with no cure. They checked: brakes, wheel bearing, ball joints and more. We replaced the front shocks and 3 months ago, the RATTLE/CLINK is still present. It may begetting worse as time pass.
Anyone have such an experience with their vehicle?

I completed a brake job on my 2008 Passion and afterwards I could hear a rattle when I hit a bump or rough spot in the road. When I held my left foot on the brake pedal with slight pressure applied, the noise went away. I pulled the front pads off and I discovered I had assembled the right front pads to the calipers incorrectly. There were clips to secure the pads to keep them from rattling . Once I corrected this, the noise went away. BTW, it is an easy mistake and the pads can be installed easily with the clips in the wrong configuration. Good luck.

I am with that heat shield reference. As my 2014 cat converter heat shield is fully disconnected and just up in there won't fall out repositions at times and I can hear it. I also had a socket wrench left in side the pocket to get to the tail light drove me nuts about a week until I found it.

This helped me for the problem. Thanks for it.
