I bought a 2003 G35 sedan and while the interior is very quiet, the passenger's seat squeaks like crazy...it's constant and it's driving me nuts! If my GF gets in the car then it stops squeaking and if I hold the seat with force while driving it will also cease.

Does anyone know exactly what part of the seat is squeaking? I tried to randomly add lubricant but that failed. I see a few threads of drivers seat squeak but not one of passenger seats.

 

look at the threads for drivers squeak and then just see if it applies to your problem. aka i have no idea.

 

I Have n 06 and it does it too, thats why I keep my seat pulled a lil forward with the back up. Or else God knows how many times i smacked the SHyT outta my seat.
