The "buzzing noise"; I can tell that I am not alone in having this problem but has someone figured out ... I fit does, that eliminates the brake rotors, tires, wheelbearings, CV's etc. ... BUT with an Altima it is probable the pre-cats. Loud humming noise when driving

Most likely, that is the sound of the FUEL PUMP. If the car is running well, don't worry about it. Try changing your fuel filter to see if that helps (usually does).
If you have trouble with fuel delivery at high speeds or under load, suspect that your fuel pump is about to fail.

hahaha,that is the common problem,IAC control problem & kill the ECU .u need to chnage both,after replace it u need to program system.good luck

I can relate my experience with a similar noise on my 1994 car with Traction control. A electric valve in the air intake made a "Hum" or "Buzzing" noise when malfunctioning. For my car, the valve was suppose to reduce engine RPM so the wheel spin was stopped by choking off the air to the engine.
So the electric valve on your engine may be getting a bad signal from the Traction control system especially since you are not applying power. Or simply the electric contacts in the part you mention are worn out and "buzzing" because the contact points are burned out and can not connect.

unfortunately this website is the pits..I have experienced the same problem with my nissan maxima.ABS..motor running when engine is off. no one seems to know the what to do, or give a definitive answer. My next step is to see is there is a lawsuit pending against nissan on this issue. From my research Nissan Corp is very silent on this issue..I feel if anyone is going to buy a vehicle from nissan or any other japanese car mfg..they have to think three times before they put their loved ones in their vehicles....seems to me they're going the way of the american car mfg companies...put out sorry cars and trucks and rake in the money....so far the south Koreans have out stepped the american and Japanese markets on reliability issues...very good quality vehicles and with a great warranty back up...do the homework...sorry to say our country that started making cars, ended up buying foreign cars that last longer and are more reliable...I am not only disappointed with our car industry....(by the way that needed a buy out) but disgusted with the way they sell their products to the american buyer as if they are sorry for misleading the american public with inferior products....Once we were a good car and truck producing country...now we arent so hot....not sorry about this post, hope someone wakes up in the car industry....otherwise we're gonna be in deep stuff ........thank yu very much. the HOO

could be a dirty throttle body or the idle control motor

Sounds like a bad fuel pump, check if the smell comes under the rear wheels and also check for a loud humming noise when the key is turned to on. Those are signs of a bad fuel pump.

sounds like solenoid on starter is worn, replace starter.

Primary ignition fault. Reasons: Bad distributor cap (most likely) or ignition control module/ignition coil.
Hope that helps
Good Luck

that sounds like you may need to replace the starter. the click you hear is the solenoid. the part that is just as important is the starter motor. unfortunately they are sold as one
