Mine is 2003 G35 Sedan. When I turn on my stereo (volume level is 7 or 8) or drive on uneven roads, the squeaking noise appears. When I turn off the stereo or drive on flat roads, the noise doesn't appear. It doesn't happan all the time. It looks like vibration makes the noise appear. I can't tell where inside the noise comes from. Does anyone have similar problem?

Thanks for the help.

 

Never heard of that one before... but if you have the sunroof (which almost everyone does) our car are notorious for having the sunroof squeek is it not that? someone help me out here with this one

 

Sure sounds like something in the sound system, if it goes away when the radio is off. Blown speaker, maybe???

 

For me when i drive over uneven pavement i hear something rattle on the driver side or somewhere ever there. It's really annoying, perhaps the suspension is made like that... I dunoo

 

Noises in my car have come from:

Rear view mirror
Infiniti clock
Rear passenger windows
keys
stuff in my center console and or beverage holder
satellite radio stations due to low band width (crackling in the sound quality)

hope this helps

 

I have the exact same problem with my 03 coupe, but can't really hear where it comes from

 

The sound is like "zi zi zi...". I think the sound is come from the speaker beside the outside mirror of the passenger side, but I am not sure. Does anyone have similar problem?
