2022 limited with passenger seat vibration and rattle

My 2021 Sport Premium with leather does not vibrate at all. Maybe like mentioned it could be the seating adjustment not sure.I do not have passengers and you would think with it being empty it would vibrate but it does not.

 

Same! My 2020 OffRoad passenger seat looks like it's having an epileptic seizure when I get around 70mph. WTF!

 

Someone on here mentioned changing the seat position 2 years ago when I first purchased my 2022. I found that slightly reclining the passenger seat helps significantly but doesn’t eliminate the problem. I just try to not look and let it pester me….. it’s a truck

 

Are you sure it’s not the passenger side seat belt rattling against the B pillar plastic trim panel. The seatbelt doesn’t always sit straight when not used

 

I've had this issue in my 22 CC with Leather seats. I also had the exact same issue with my 07 4Runner. The notches or keys that Toyota cuts in the seat back mechanism are way too loose and causes this. I put some adhesive backed foam on the passenger seat of the 4Runner. I am going to have to do the same with the Tacoma.
