I recently purchased my 350z and after a few months of having it, I noticed this strange rattle in my passenger door. It only happens above 2800ish RPM and it drives me crazy. Is this a common defect? Anyone else with this problem? Any advice is appreciated.

P.S - This is a great forum and I am glad I found it.

Cheers

 

I have a rattle over in that area too. I don't think it's coming from the door, though. have you ever had a passenger put some weight on the dash and the rattle went away? I find that for my particular one (if it's the same), if the passenger puts some weight on the dash closer to the door side, the noise will stop.

I tore the dash apart yesterday and double-sided taped the area that I thought was causing it, but it wasn't the fix.

 

I have both, under the airbag and the passenger door. I just found out it was the door today while I was driving when I pushed on the panel and it stopped, now I have to rip apart the dash and the door panel

 

I started getting the same rattle after I put in my new sound system. It also stops when I put some preassure on the doo pannels. I will be taken the door panels off and dynamatting the doors once the global cooling recedes here in VA.

 

^ yea I have the rattle too after a new speaker system. Just on the passenger side really. It pisses me off but some have told me it could be the window as well.

 

The passenger side door grip bolts into a small square nut on the top. This little nut is held in with next to nothing, and comes detached from the door easily which allows the door panel to vibrate the nut against its housing. I'm going to weld the damn thing on in spring.

 

I have alarm LED, center console, driver seat, and right corner of the dash rattles.

I just say F it and turn up the tunes.

 

If you document this welding fix, I will totally follow it. What an irritating little problem. Drives me crazy. I thought my window was broken, but I figured out that wasn't the case after a bit of puttering.

 

Damn I have the same issue. It all started when I did the window motor fix. I must have missed a bolt. Going to tear into it this weekend.

 

i have the same passenger side rattle but i think its more on the buzzing/vibration side

 

What I do when I hear a rattle I can't find is have someone else drive me around in my car and have me look for the rattle. 9 times out of 10 it helps but the fact that your rattle is at a particular rpm is odd because most rattles are just loose panels but the fact that it does it at 2800rpm says it might have something to do with the vibration frequency of that RPM.

 

I have the same problem since I upgraded my sound system. The problem is inside the door.

 

Definitely. I'll probably start with something a little less aggressive, maybe a strong epoxy, and let you all in on the results.

 

I know its been over a year, but bump to see if the epoxy approach worked...hell, bump for any solution. I'm starting to go crazy with this stupid rattle and I'm planning on taking apart the passenger door this week.
