all g35's squeak and rattle that's just how we roll!

 

I bought my 06 used, and it had the loudest most annoying squeak coming from the passenger dash area. It would squeak constantly, didn't matter if there was a bump, smooth or rough roads. Turns out it was the inside of the dash hitting the metal frame.

I fixed the squeaks and rattles by using 3 rolls of felt tape from Nissan, and 3 rolls of foam camper tape from Autozone/Pep boys. Basically any area where plastic and metal make contact I put some of the tape in those areas. So sometimes I had to take parts completely apart (such as the AC vents, which are made up off about 10 pieces of plastic).

I've had to take completely part the center console, passenger dash, steering area, instrument panel, both door panels, and the driver side rear panel. But there's no squeaks or rattles. The only noise that I have is clunking from the SPL compression bushings, though they are loud when on rough roads. That's another issue.....
