I have the same problem. I'm still looking for a fix without having to dismantle the whole door although that seems to be the only option.

Check this forum and scroll down for the explanation.

Hey guys, I have had this issue before and again now, just so yall know, you have to replace your Window Regulator Unit to fix this rattle issue.

figured i would follow up here since this thread helped me a lot. as GalletGun stated, it is the window regulator.

first dealer i went to said basically screw you. next dealer i went to went ahead and replaced the window regulator under warranty (they replaced the outer "frame" of the regulator, not the motor). this fixed the problem.

Thanks!

I had the same issue....but i will say that the door hasn't been quite the same since, at first door glass was off, took the car back and they fixed it but just doesn't seem right, so be warned it seems that they have to re-adjust the glass and chances are its not going to be 100% the same way as it was from factory.

Agreed. They have to reprogram the partial lower/raise that occurs when the door is opened/closed. Now mine does hit the top a little harder than it did stock

YES I JUST REALIZED THAT TODAY. Spent 2 hours looking for it and couldn't find it

So I just seemingly just fixed my passenger door rattle. I found 3 10mm bolts just chilling at the bottom of the door near the weep holes. They didn't look used. Removed the speaker to get better look. Two were visible. Last one I used my inspection camera to find. Then sent it back in on a rescue mission with a magnet. It fixed door vibration problem for sure but not sure if that cured another mystery rattle I cant pin down its location. BTW Skrillex "rock n roll" worked quite well to duplicate the door issue. :D I kinda want to mail the 3 bolts to the factory in Japan with a "someone might be looking for these" note. 2011 370z sport touring 40k

Had same issue & dealer finally found a creative fix that worked
 

Well as it has been mentioned, the window rattle on the drivers door can return and has been an ongoing issue for some. This typically happens when the window is fully in the up position and disappears when slightly cracked.

The dealership was as frustrated as I was with this problem returning so quickly so a new regulator was ordered after several more attempts to stop the noise were unsuccessful. Long story short, the new regulator would have also rattled away & it has to do with the way it has been designed in it's mounting points. It is secured with one mounting screw but the other mounting point is done by using a rivet. This is where the problem arises. SO... with a bit of creative thought, some foam was placed in between that area to prevent that noise created due to the weak contact point using a rivet that can not be properly tightened. This was the explanation I recently got and it seems to be correct. The rattle is totally gone and I don't believe it will ever return now. Such a PITA noise for such a simple cure! Anyways, I hope this information will help others that may run into this issue. Regards Forum Members...:driving:

Replacement door regulator may creat new issues
 

I had this work done at my local dealership and in my situation the glass was way off in positioning afterwards as well. So far off that it was distorting my window rubber seal. The 2nd attempt was good but then clips and other things were damaged & another trip was needed. I also agree that 100% same functionality may not be possible as it was assembled at the factory but mine is totally acceptable again now. OR... Maybe this techs at the dealerships just rush the jobs and just don't pay attention to detail like they should!:eek:

I did have to do a Window Reset myself later on. The glass was failing to lower very intermittently. That's been OK since the reset.:tiphat:

did you take pics by chance.

Need to show this thread to my dealer before my warranty runs out.

Would it be possible to remove the rivets (drill/chisel/grind) and replace with screwed fasteners?

Tis exactly what I did.
