Possibly a wheel bearing
the engine the engine
The humming is a series of explosions in the engine happenning very quickly. Could also be an electric fuel pump if the vehicle is equipped with one.
Raise the hood and have a helper start the car while you listen. Check around the top of the engine to find the humming.
Check the power steering pump for the cause of the noise. I sounds like the pump is causing the whining and is either low on fluid or possibly going bad.
MAKE CAR MAKES THE SAME NOISE AND REPLACING THE PVC VALVE FIXED THE PROBLEM
The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.
it does that because it has a generator which makes the engine makes these sounds
The reason your car is whining is because your car is low on tramission fluid. but i have checked my transmission fluid..? do i need to flush it out and get new transmission fluid?
the whining noise is probably your passenger whining about the stupid questions you ask
The question you are asking is the same as a question like: Is building a house? or Is driving a car? You can built a house, you can drive a car and you can surely sing or hum a melody! Is singing or humming a melody, the act itself is not! But depending on what you are humming or what you are singing, the part that comes out of your mouth can be a melody...
probably the abs pump...mine has started whining after sitting >6hrs, during which the abs has bled off pressure (which it shouldn't)-:
