[MotoX16]

Hey guys,

I recently picked up a 2017 brz PP and am hearing a clunking noise coming from the rear I can't seem to locate. Car is all stock with just over 15k miles.

Noise is present going over bumps at low speeds (under 50) and seems to go away at highway speeds. It's definitely coming from the rear, more so the passenger side but sometimes the driver's side as well. It's sounds like something is loose and clunking around.

When I had winter tires put on I asked the dealer to check out the rear suspension and they didn't find anything loose, and of course couldnt hear the noise. I don't know how because it's there literally every time I drive the car. I tried folding down the rear seats thinking it may be the latches. The noise got louder so I assume it's coming from the trunk area. I noticed my spare tire wasn't snug and the trunk tools we're a little rattly. I tightened down my spare and added a bunch a weather stripping to the underside of the foam tool holders. Noise didn't get any better.

I know brz's are kind of famous for interior rattles but this just seems ridiculous. It's my understanding that tsb 12-140-12 is only for early models but I wanted to hear if you guys had any other suggestions. My nest step is going to be removing the spare and tools all together. Which I'm actually hoping doesn't work because I'd rather have that stuff in my car.

Sorry for the novel but thanks in advance for any help!
