I got my car back from the dealer and I have started hearing creaking sound from the rear deck of my 03.5 sedan.
Seems to be coming from the rear windshield or maybe below the rear deck but I have not been isolate it. I even sat on the back but not able to figure out.

Anyone experience with this or have any suggestion or feeback please let me know as this creek noise is driving me crazy.
Thanks

2003 G35 Black Sedan

 

I have it!
Brought it in last time and they said they fixed it but I still hear it when the frame twists. Sounds like the back speaker tray on the right. I'll let you know what they find the next time I bring it in...do the same if you find the fix.

 

Aha! I have the same noise, 2004.5 sedan. I posted this in the suspension forum here but I'm still not too sure what it is. Check out my post and see if it seems like the same thing.

 

Had the same problem. Brought my car in and they said that there is a pad or foam which slipped and made the rattle. Easy fix. Funny enough, it was on the left side. As soon as I picked it up, the right side made the exact same noise. I had to bring the car back in to get it fixed again. GL.

 

I just bought an 04, I have the same problem, did you ever figure it out or get it resolved?

 

I have an 03' Sedan and I also took mine into the dealer to get a speaker rattle on the driver side fixed and it came back with the rear deck creak also. And of course now the passenger side speaker rattles. I am going to take it in tomorrow to see what they can do.
