Hey I have a 07 g35 sedan and my car is making a humming/ pulley turning noise I don’t know where it’s coming from but it’s low sound then get higher over times at times . it only happens when the car is park or just stop for a while and no it doesn’t do it when the car start up it’s does it when I drive around for a while but if I turn the car off and turn it back on it goes away and comes back . I have gotten my power steering pressure hose replace a month ago idk if that’s the reason of the noise so I’m just coming on here for answers .

it could be power steering related. do the sound change when you move the steering wheel left and right (engaging the power steering pump that way)?

 

Check Washer fluid reservoir anchor. The Plastic clip thing can break and cause a low frequency rattle when stopped/idling

 

Yes the sound change when I turn the steering wheel it stops for a split sec then comes right back

 

ok I will check that to I was just looking ok youtube few mins ago it could be a bearing in my powersteering pump or alternator
