Whining noise during idling

I have had my 2008 Enclave for about 1.5 months now. About 2-3weeks ago I started to hear a very noticeable whining/humming noise coming out the driver side when the car is in idle or at a stop light. I turned off the AC/fans, the noise is still there. I am pretty sure this noise is not the engine sound either. And one can only hear such noise from inside of the car but not outside. Brought it in to the GM Service dept today, the tech can also hear the noise but not sure what it is. We tried another new Enclave on the lot, and the noise is not heard in that one. Planning to bring it back to the Service dept next week for them to have a deeper look. Has anyone experienced the same problem? This car is supposed to be very quiet, and this noise is getting very annoying!

Re: Whining noise during idling

I think my E has the same problem. The noise has gotten worse over the 8 mo period.
I dropped the car off two weeks ago for camshaft service and also mentioned the noise. The Service Adviser heard it during a ride.

Got the car back today, drove it for a short time. They replaced the power steering pump. The noise has significantly subsided but is still present. Iam very interested to know id there is another solution...

Very funny JustDriftin...I like your humor At least you were able to find out what the "problem" was and remove it. I hope I can find out as easily where does the "whining" noise in my car come from

Re: Whining noise during idling

Have you turned Off the radio? Not just lowered it? Radio "whine" is very common on all brands.

Does it increase/decrease if in Neutral, and you rev the engine?

I turned the radio off and the noise is still there.

After doing some research on this forum, I suspect it might be the power steering pump or low power steering fluid, but I could be wrong.

I will try your suggestions and see if the noise increase/decrease in Neutral or when the enginer is reved. What are you suspecting?

Thanks

Re: Whining noise during idling

I was thinking other than engine equipment (fans, radio, exhaust, etc). You've eliminated most. If noise rises and drops with the eng rpm, in Neutral/Park, probably an engine internal or belt driven accessory noise. Power steering usually reveals itself, cause noise changes while idling and just turning the steering wheel. (slight pressure noise, not an obvious "whine", is of course normal.

Good luck & keep us posted.........

Got my car back from the shop today. The service manager told me they think it's the fuel pump making the noise, and the noise is actually generated from the back of car (where the fuel pump is located) and travels to the front. They have ordered a new fuel pump to replace the "bad" one in my car.

Bad fuel pump? Really? That's unheard of, especially for an Enclave that only has ~1000 miles? Well, the new pump will be here next week and will update you guys how it goes.

Re: Whining noise during idling

My 2001 Park Ave had a whining noise that was the fuel pump. It actually was noisier when the tank was low on fuel. The fuel pump is in the tank.
