Rattle Noise coming from backseat/B Pillar

[Pittjeep15]

Has anyone had this issue? I noticed it shortly after picking mine up in September and it has gotten consistently worse. I have a Limited with the 60/40 bench. I cant figure out if it is coming from the bench seat or B pillar but it is extremely frustrating and seems to rattle (sounds like metal on metal) anytime I start driving, reversing, or the body flexes?

I have a service appointment set up for next week, any insight would be helpful

I have a rattle as well but I'm 99% sure it's the sunshade. I don't hear it when it's rolled down in the door.

Passenger side B pillar rattle.

Picked up our CGL Overland on Saturday. Just started to get an annoying rattling from the passenger side B pillar area. Need to ride in the back seat while the wife drives to see if something simple. I checked all the easy things. Almost sounds like where the door hinges mount to the pillar...
