There are a couple of things to check. If your power steering pump is low on fluid, or a bad bearing is in the Alternator, they will whine. The PCV valve or any hole in the Vacuum lines will whine as RPM is increased. Even having the Air filter box not fully seated will make a whining noise.

Now both automatic and manual transmissions can whine as RPM is increased. Check fluid for each.

Serpetine belt and pulleys-can make noise.

Sometimes you can shift into neutral at any speed and the engine rpm will drop almost instantly as the car rolls at speed. If the problem disappears as soon as the rpm drops, then an engine part probably is the reason.

SOURCE: Pontiac Grand Prix GT grinding and whining noise when turning...

If you have a warranty from your dealer, you paid for it, or whether it came with it, it doesn't matter, you MAKE them honor it. Take it back there, and MAKE THEM FIX IT! This shouldn't be your problem if you have a warranty. If they aren't honoring it, threaten them with the BBB or court. They will shape up.
I would say power steering pump.First check to make sure there is fluid in the reserve tank and at the proper level if not top it off and whine should stop.If level is correct then maybe try flushing with fresh fluid.
3.8L engine the power steering fluid was never toped/checked.. because it is a pain in the *** to get at (behind the hot as hell alternator), so it probably ran dry, top it up is probably all you have to do.. if the whining presists then you will have to try and bleed the air out by jacking it up, engine off, turn the wheel one side to the other about 25 times.. if that dont quiet it up then you will have to replace the power steering pump.


Power steering pump / fluid level is not hard to check - it is located below the alternator on the passenger side of the engine bay. You need a light to see it. You can get your hand down from the top of the engine to loosen and remove the cap/dipstick.
Here is a link that should help you.http://www.paulstravelpictures.com/GM-Pontiac-Grand-Prix-GTP-Power-Steering-Whine/index.html
Good luck and thank you for using Fixya

SOURCE: 1996 mustang gt makes a reking noise when turning

There are several possible causes to your problem.

Most likely it is a ball joint.
A bad strut mount will make a similar noise. Sometimes dirt/rust in-between the strut spring and the rubber insulators can cause a creak.
If the environment is really dry or the rubber bushings on the car are really old, they can cause a creaking noise.

I would have it checked out because if it is a ball joint, it will eventually cause uneven tire wear and can even separate, resulting in total loss of control of the vehicle.

SOURCE: whining engine noise

If the noise increases when idling and reving up the engine then you must check on the engine pulley, the belt idler pulley, the water pump , alternator or the a/c. But if the noise increases when you are moving then you must check on the wheel bearings, the drive shafts and the inspection of the mudguards for tyre rubbing. If so you will have to jack up the car and check for faulty bearings, drives or tyres. SInce the noise can be traced to the point of generation , you will have to have a friend also to check on one side for pinpointing the sound and identifying the part. This must be easier to find and you can easily replace/repair/change the part concerned. Hope you try. Good day

It sounds like a belt thats slipping. You have a sticking puley somewhere, take off the belt and rotate all of the pulleys. Usually its an AC compressor pulley so pay special attention to it. The whining noise that it makes while turning, is it the same as the squealing noise? If so it could be a problem with the pump, check the fluid level and see if its an odd color or has an odd odor (like burnt or black). Hope this helps!

How to fix whinning noise when car is accelerating, or turning? Is the whinning noise an electrical issue, fuel pump, power related, etc.?


the whining noise is your engines alternator bearings
they are worn out , the alternator is close to failure
it is barely producing any voltage
( the battery light in the dash only indicates that the alternator is no longer generating any amperage )

Ac makes whining noise on a 2004 Pontiac grand prix


Is the whining noise coming from the engine compartment where the compressor is located or is the noise coming from inside the car? If the noise if coming from inside the car it could be your blower. When a blower wears down the bushing is the first thing to wear down and it begins to have play. That makes the blower/fan vibrate making a loud whining noise. Replacing the blower could solve that whining noise.
If the noise if coming from the AC compressor, it also could be a bad bearing within the compressor.

I have a whinning noise from under my truck when i accelerate


It sounds to me, like the pinion bearings are going out, in the rear differential. It makes a whine when accelerate and quits when let up. That a common problem with those trucks.

Same problem: a high pitch whine after extended driving


Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).
