I have been noticing this incredibly annoying high pitch squeak that comes from somewhere around the plastic trim in the 3rd row seats (where the cup holders are on the sides). It will sound constantly when driving over uneven/rough pavement which is everywhere! Even slight bumps will generate this.

I tried knocking the panels to see if it works to no use, I can def feel the squeaks if I force the panels by moving them in all directions (as if there are contact points with each other that create the squeak.

I forced some latex gloves around the main squeak (it sounds much louder from the driver's side trim) to see if I could quell it but I only noticed a marginal improvement as the noise is still VERY clear when driving...

I am ready to take the whole rear piece apart and see if that is indeed the problem but I have no clue how to get in there.

Anyone else have any rattles/squeaks/noises in their cars? Any luck tracing them and better yet, FIXING them?!
