I hope everyone is enjoying their rides! Recently, I've been experiencing an annoying rattle noise emanating from the B-Pillar area, specifically near the seat belt height adjuster. After some research, it appears that many others are facing the same issue.

Would appreciate anyone’s recommendations on fixes… my NX350 was one of the first few hundred that came out of the Canada factory. Also had the noise coming from the cargo area!

To tackle this problem collectively, I'm starting this thread to discuss possible solutions. Has anyone successfully opened up the B-Pillar trim to access the components inside and apply some insulation to resolve the rattle? If so, could you please share your insights and the steps taken to remove the trim?
Whether you've already fixed the issue or have any tips on how to access the B-Pillar trim without causing any damage, your contributions would be greatly appreciated. Let's pool our knowledge and experience to find a reliable and DIY-friendly solution to this vexing rattle problem.
I also want to know if anyone has figured out how to fix this issue. The tiny rattle sound comes and goes for my NX, but it’s been happening more often lately, especially when the road’s a bit bumpy, particularly with the recent warmer weather.
I did this to both my new 7ESes. Unclip b pillar panel by pulling on it with your fingers (not 100% sure it's same as NX), then i took a look at the metal track the seat belt anchor slides on. there's a metal rail. i took a thin piece of durable gaffer's tape , very tiny piece. maybe a thin strip 3/4" long, and covered the rail on ONE side. this prevented play in the seatbelt anchor so it wouldn't rattle. then you just push the pillar cover back on.
Put the tape here. the idea is to place it where the seat belt anchor would normally rest when you drive. so slide it down first. put the tape, then slide it back up (or whatever direction works for you) keep in mind when reassembling the trim panel, the plastic button to release the seatbelt has to line up with the anchor. so line it up first and make sure you can successfully slide it up and down.
I had the same thing, was only noticeable when driving with windows down. The air would shake my driver side only. Dealer replaced the entire seatbelt housing, so far so good but it’s only been a few days

Thanks for sharing the picture. I think the issue is the same in NX 350 but my question is how to open the B-pillar trim. I looked at the trim parts online and it seems they have a lot of clips and screws. I'm not sure if it's an easy pull to unclip the trim. There should be some kind of step-by-step dismantle tutorial but I can't find it.
Finally fixed the buzzing noise and rattle in this area, pillars are now dead silent. However, I've noticed some other vibrations over potholes from dashboard and somewhere in the rear seat area. Not a major issue, but I'd like to address these noises too. Anybody else experiencing cabin vibrations and noise over potholes?
p.s. I’ve also added the SD sheets to the body frame too.
Sorry, 1st time posting (will introduce after this post) I came across your issue with the rattle in the B-Pillar in the 2nd gen NX and I am having the exact same issue!
How were you able to remove the trim? Is it as simple as moving the side gaskets and carefully pulling or does it need to be removed from the kick plate up?
I do know there are side airbags as well and not sure if there is a bolt behind it as well.
any help is appreciated bud. Glad you were able to fix this annoying part. Car is pretty much silent except for the passenger b-pillar

It was straightforward. follow these steps:
REMOVE THE FRONT AND REAR DOOR OPENING TRIM WEATHERSTRIP
REMOVE THE FRONT AND REAR DOOR SCUFF PLATE
REMOVE CENTER PILLAR LOWER GARNISH
REMOVE CENTER PILLER GARNISH ASSEMBLY
The challenging part is how to make the plastic parts stop rattling against each other!
