B Pillar/Rear Quarter Glass Rattle

Blizzak

Hello guys, been dealing with this weird metallic-ish rattle coming from the seat belt receiver/rear quarter glass area for a LONG time now. Searched to and fro on this forum and from my research over the past months nobody quite has this exact problem.

I attached a video with this sound... this has been happening with my STOCK exhaust and my now aftermarket one. This happens only at speed(60+ mph), there is no sound at city speeds(10-45 mph). Also this same sound is happening on the passenger side in the same area but that one doesn't rattle all the time.. and when it does it's very faint.

Today I removed the rear plastics and drove with them all off... noise was still there. Pinpointed it where my suspicion was... b-pillar/rear quarter area. Also previously took the exterior b-pillar cover off and the noise was still there. Running out of ideas... I'm thinking I may have to buy a whole new seat belt receiver. Or could this be a heat shield under the car?

Any help would be appreciated, getting desperate

I have the same rattle in my 16 NISMO, but the push-in holder on my B pillar trim is broken, so I just assumed it was that. Mine will rattle regardless of shred, but it has to be on a rough road. It's quiet on smooth asphalt or concrete.

Yeah this is so odd because it only happens at speed. Next time I go to the shop I'm going to have them check the heat shields under the car... I'm running out of ideas

I’m sure this is way out from left field, but I seem to remember a bunch of owners here complaining about a “clicking” noise coming from the rear axle. It was pretty well documented here.

Again, just throwing it out there. Good luck and let us know how you make out when you find the problem.

I'll check this out, may be the issue. Sucks though man I remember not too long ago this car had none of these issues... seems like the more miles I put on it(65k now) this sh*t is falling apart
I just hope the new Z doesn't fall victim to all these horrendous rattles the current has. Wishful thinking

Little update.. been having another rattle/vibration only at a certain speed and rpm. Research tells me maybe my tires need to be balanced? I can trace the sound to the passenger side under the car(sounds like its coming from near the cats area)

Also was able to get the car on the lift and I was surprised to find no loose exhaust parts... I'm out of ideas

UPDATE ISSUES SOLVED:

After dealing with this noise on my SECOND Z (Nismo at 16K mi) I have finally found the issue… and it’s a faulty defective manufacture part. The noise is coming from the seatbelt bracket (where the 14mm anchor bolt is) After this part came loose and stripped I took it to the dealership and was replaced under seatbelt warranty… hope this helps
