So i bought my first a 03 g35 coupe, when I'm idle and then accelerate a little, i can rear the rear deck or seats make a buzz sound, but only if i go slowly , if i go faster it makes no noise, i have a video if anyone wants me to send to help me out, I'd appreciate it ALOT!

 

Welcome to the forums.

Post the video on youtube then put the link here and it will automatically embed the video.

 

I tried but it says invalid url, however here's the link everyonehttps://youtu.be/t1HKTMSk_TU

 

 

Yes that one, thank u

 

That's weird, I would take out the trunk carpet, spare tire, and the plastic spacers on the side of the spare tire, basically empty the ENTIRE trunk until you get down to the wiring harnesses and modules. Look for something like spilled pepsi.

Then fold down the rear seat, in the very very middle of where the seatback meets the cushion dig around for the red colored ripcord to fold the seats down, clean THOUROUGHLY where the seatback touches the plastic trim.

My gut feeling is you'll end up removing the plastic interior trim over the rear side speakers because someone probably replaced them and either added some kind of sound deadening that has degraded and now makes that sound, OR they just left stuff loose so it creaks as the chassis vibrates over things in the road. If you watch just the camera mount in the video the creaking sound is DIRECTLY related to the vibration you see on the camera mount.

 

Here's the video link for anyone else who wants to chime in .

 

Yeah the cellphone mount was a different creak/vibration
