Rattling coming from B pillar?

[chanmanx2k]

Anyone experience some noise rattling from the B pillar somewhere? My audio system or subwoofer must be vibrating something loose in that area but I don't know where it is coming from

Is it your passenger side seatbelt buckle? Mine sometimes rattles on the B-pillar if it's caught slightly sideways between the pillar and seat. I just straighten it out and it's fine. Took me a while to figure that one out! Heard others say the same thing happens to them.

FYI: My 2020 had the slight rattle in the B-pillar at highway speeds. Mobile service just repaired it with an updated part.

Same here, my 2018 has the same b pillar buzzing which is very noticeable when driving on the highways. I've narrowed it down to the seat belt height adjuster on the b pillar. I'll add this to my next round of repairs for the mobile service folks.

@XLR82XS,

Did that fix the issue? No more buzzing/rattles?

When I went to service they said it was common and easily fixed. and would also cost me 2 hours labor since I was past the "rattle" warranty which is apparently only 1 year.

Here is a video to stop this rattle.

FYI, I did not find that this actually fixed the issue. It's an easy thing to try, but my rattle is coming from something else there...

Yep. No buzzing for me, just a VERY SLIGHT clicking only heard over 70mph and when my ear was close to the seat-belt adjuster. This is with all windows up and audio off.

Just realized I’m a 2018 and don’t know if Mobile will retro mine according to a previous post but I’ll attempt it. Didnt realize they actually had a revised part for it. They’ve been just putting felt tape in there in an attempt to fix it from what I’ve read.

No it did not fix the noise 100%. Clicking still present but very faint and you have to hold you ear against the B-pillar to hear it with silence in the cabin.
Beyond that there were a couple highway-speed noises pinpointed by a mobile tech today. Loose panel at the rear just behind the bumper. Tech installed foam in that area plus at the plastic underneath both rocker panels.

*5/5/20 UPDATE* Car was at SC for axle clicking. B-pillar clicking/fluttering been getting progressively worse over the last couple months including rattle from the bottom of the panel over rough pavement ~40-50mph. It's now heard at lower speeds where before it was highway only (70+mph). SC telling me they can't hear anything and I'm fed up. The car literally has no other rattling issues. I plan to take it apart and use foam tape, etc... and see how that does. Very upsetting .......

Sometimes it helps to be an old fighter pilot. I wouldn't hear that in a hundred years.

Folks, I have had a buzzing noise coming from driver side B-pillar (maybe passenger side as well now after 6k miles). Does not always happen and really depend on road surface and frequency that gets transferred from tire -> suspension -> frame -> trim?. I did some felt tape and applied some trim dressing 3 weeks ago and now the buzz is coming back...will try a more durable dressing this time. Will update back if I am successful on resolving the issue

*B-pillar noise solved* 1" foam tape on the edge of the wheel liner where it contacts the fender. No more ticking noise at higher speeds.

Would you be able to post a couple photos from your fix? Or at least of the area?

TIA!

I have some occasional buzzing also. It doesn't bother me.

Not my car but same idea. I ran the foam tape up higher until the gap tightened about the height of where the camera/repeater is.

That buzzing is most likely the seat-belt height adjuster - plastic on plastic slide. Both my 3 have never had that issue.
There could be buzzing from the pillar mounting tabs and the foam tape on those will certainly help remedy that.
