well, i came home, turn off my car and i walked away from my car and when i was ready to get in my home, i heard some strange noise under my car, i was like wtf, i went close to my car and i think its under my car, near to exhaust but im not sure, anybody has the same experience with me?

 

Check your oil level...

you gotta be more specific, but it could be valve lifters ticking, your pipes could be cooling down, or the cat. It's probably normal. depending on the severity.

 

oil level???

Im thinking maybe its normal

 

Yes...usually if you hear a ticking (and it's not normal) it is your oil level...Just park your car on a level surface, pull out the dipstick, start the car for 5 seconds, kill it, put the dipstick back in, check the oil level...if it's low, refill it, and see if the ticking persists.

 

mine makes 3 or 4 clicking noise each time i shut it off. I only hear it when it is quiet. other than that i dont know.

 

Mine did that too for a long time....doesnt seem like its a big deal...

 

i was outside for couple mins and when i went in my house still... noise, for a moment i was like maybe is a da*n bird but... nah

 

i've got this whining/buzzing sound for couple minutes after i turn it off.

 

I also noticed that on my car. No biggie so far.

 

There was a tread on this like a year ago on 00-01 models. Its something resetting itself and I can't remember what it is....Icy2kSE I think you know what it is. Its normal, and nothing to worry about. But I'm not sure if its the same noise your discribing on your 02-03

 

I have something liek that. about 5 seconds of wering under the hood on my 2k when I turn it off. Eh.

I also have the whirring/buzzing noise shorty after turning the car off. It's subtle, I usually only hear it in the garage where it's quiet.

 

when i shut my car off and if its really quiet there is a quick funny noise, im guessing its nuthing

 

Is the sound similar to like a small engine or servo motor. I had the same engine noise for when I would shut my car off too. It was the electrnic motor mount (front one). I spoke to a friend of mine and who works for Nissan and he told me to unplug it. I did so but I need to bring it in to get repaired.

Hope this helps!

 

fuel pump?

 

It's fuel tank pressure-related. If you unscrew the gas cap it goes away immediately, otherwise it takes about 5-10 minutes. It's normal.

 

Possibly be the electric fan?

 

if it sounds like drops of water falling on a piece of tin thats normal. its just the exhaust colling down.

 

sounds like a electric motor mount, if your car is a automatic then it will have those electronic engine mounts. Locate the plug and unplug it, see if it makes a difference, you will not get any check engine lights or anything from doing that. In the last few Nissan TechTalk magazine periodical Nissan dealers get, they had a little blurr in there bout the motor mount buzzing problems.

 

So what did the TechTalk magazine say specifically about the buzzing problems? Is is truely a problem that needs attention or just an annoyance that can be ignored?

 

it could drain down the battery if its left buzzn for a long time. Thats about it.

 

here's the TSB about the buzzing from the Motor Mounts... http://maxima.theowensfamily.com/tsb/NTB01-010.pdf

 

It's only the throttle body closing....it's checking something when you turn off the car.....that is normal.

 

i dno if u 5th gen guys have but it may be the power antenna

 

OMG......IT'S WHAT I SAID.......

 

i've had the same buzzing noise coming from the rear driver's side.

finally raised the rear of the car after coming home from work, and it's definitely coming from a module right next to the rear driver's side wheel. i guess it's a module related to the fuel system or braking system. i have no clue what it is yet, but it's definitely not the motor mounts in my case.
