rattle left rear side
 

Dear All,

I aslo psoted this in the general topic, as a newby I still need to find my way and probably should have posted this question here. :D

We have bought a 2012 GT86 automatic just a couple of weeks ago (80.000km). We love the car and is a well fitting addition to our Camry and 2004 MR2.
At higher speeds (100kmh / 60MPH, +) a rattling sounds occurs. It does not sound mechanical but more random. The sounds seems to come from the rear left side and seems to become louder with changing driving direction (up the road or down the road) and or stronger with higher wind speeds. I have checked in several gears and this does not affect the sound. I have checked the underside of the car and could not find any loose heat deflectors or something similar. The only thing I could find being a bit wobbly is the piece of plastic trim (part of the inside of the rear wheel arches) sticking out in front of the rear tire. (door side) I think it is a kind of water or whatever deflector.
I could not find any screws to tighten this. Now my questions:
Does this sound familiar to you?
Could this be our noise?
How to tighten or fix the rattle?

Many thanks for your insights and ideas.

I once had a socket hanging out near the spare tire tools under the trunk liner making noise.

A similar noise at the front left was a loose cable tie mount under the hood along the side of the engine bay.

I hope your issue is as simple and harmless..
