Rear seat rattle on the floor catch?

Guys

I think I may have found the issues without pulling any plastic trim. Usually rattles come from lower places on the car and we pick them up in our ears. With that being said...I took the bottom bolt that holds the seatbelt to the bpillar. When I removed it, I stuck my finger in there and realized there is a metal-on-metal layer that is not welded together. You can put your finger in the hole and make the tin metal sound with it. I stuck some 3M tape in there and around the bolt where it holds those pieces together and that seemed to have stopped the tin metal sound issue. It has taken 3 weeks to find that crap.

Hello, thanks for posting this. I’ve been chasing this metal on metal sound for 2 months and it’s driving me crazy. Sorry, I’m not quite following your solution did you happen to take any pics as to what you did exactly? I’m looking at my LC but can’t visualize what you did exactly. Thank you!

I have not taken any pictures. I plan on checking the passenger side too. All I did on the driver side was put 3m tape between the 2 pieces of metal within the pillar. It’s super thin metal and easy to slide some in.

Ok thanks. So you just had to pry the plastic cover off I assume?
 
The dreaded rattle is driving me nuts. I pulled apart my interior plastic trim from inside rear quarter panel, rear passenger door, B pillar seatbelt assembly, and padded every potential source of rattle. I purchased a door striker plastic guard as well as tried rubber tape on the catch to no avail. I padded the rear seat latch and rear seatbelt lower anchor per other suggestions. The rattle is coming from the door. This 250 series LC is trash. Sounds like a cheap aluminum can. It's build quality is nowhere near the build quality of my 21’ 200 series. I have a video of the rattle over some dirt roads with small bumps. One video is with the window down and the other with it up. I'm holding the phone over my left shoulder recording (video file too large to upload on forum). I planned to bring this to the dealer and have them address it, but it sounds like they are incompetent and I don't have time to bring it in to them 2-3 times. I believe the door seal is not up to the task and there’s too much play in the door and it’s clicking metal on metal. I want to put a sledge hammer through the door and hope a new replacement won’t have the same rattle. Has anyone had a dealer address this properly? Surely, there’s got to be a TSB on this common problem. Otherwise, I have a black on black 2024 First Edition with 4,200 miles for sale.
 
Definitive Fix! I did all of the other suggestions from other posts. Thank you for the suggestions. I still had the dreaded rattle. I finally have a definitive source and fix. Well two. #1 culprit is metal on metal contact inside the door. If you pound the outside of the door (don’t go crazy) over the drivers side passenger door near the upper door hinge you will hear the tap. It’s the outside door panel clicking against inner bracing (see photos/red). I took off the door panel (again) and wedged sound deadening foam in the groove between inner door bracing and outer body panel (circles in green). That should do the trick. I noticed one possible source on the backside of the interior door panel near the bottom (red circle). It’s a cheap bracket that holds the sound deadening material (go figure). I padded the backside of it (see pictures-green circle) and the sound is gone. Hopefully, it works for you as well. I still did all of the other suggestions, but this did the trick.

What dealer in Florida?
 
I'm wondering if there was supposed to be "panel bond adhesive" or a sealer applied there......... Mine doesn't have a rattle but If I ever have to take the panel off I will have a look see.

Update: The rattle is back! Now it sounds like the actually glass rattling in the window frame. The rest of the door is solid. Did anyone else or their dealership discover anything with the window or door seal similar to TRD Jon Tundra front window? I added weather stripping to the door and it did not fix the rattle on LC.
