I have had my 03 sedan for about 20 months now, and i realized that during the cold months out here in california (which arent many) my front seat seems to make a squeaking sound whenever i go over speed bumps or drive on a rough road or go over any uneven road.. you guys think its a mechanical problem or that the seat just needs a quick dose of some WD-40?

Thanks

 

Try this thread: DIY : Possible creaking seat fix

It's been a while since 2003.5 came out, lots of issues have been previously covered by other members, doing some search first might save you some time waiting for reply.

 

Thanks for the help, i know i should search for old threads, but i had a hard time finding this one...

 

I had the same issue. Trust me it only gets worse. Im on my 3rd seat tack and had to fix it myself as infiniti never fixed the problem. I would reccomend some coupe seats.
