Need help with my 2012 qx56

[Sergeloboda]

Hi guys! New to the forum. I’ve got 2012 qx56 couple years ago and right off the start started getting humming noise from the front driver side. It’s not very loud. Humming starts at around 10mph. At higher speed (35-75 to whatever) when I make turns the humming pitch changes and gets a little louder. I took it to dealer 3 times and that was a waste of time for me (don’t trust my local dealer anymore). Now I’ve changed hub assembly, the noise was still there. Changed cv axle, noise is still there. Any ideas? Could it be power steering pump/column? Thanks

when you want help over the internet, it's helpful to give more detailed info than if we were in person to see the car.

so at first the noise was not there but showed up later correct?
can you make an audio clip of the noise. "humming" could be anything, and with the way sounds travel in a car, the sound may be originating from some other part of the vehicle.
so the sound gets louder with speed?
so what did the dealer say? if you took it 3 times did you get 3 different answers?
has your car had the timing chain recall done?

It’s not loud enough to record. The first time I took it to dealer they said no issue found. Second time, they blamed the tires. I know it’s not tires because if I drive on a gravel road, it makes the same noise. Third time they said that passenger front hub is making a little noise. I got the car with 98k miles on it and I didn’t notice that humming on a drive test. Few weeks later after buying I noticed it. The humming starts at around 5-10mph, it sounds like something is spinning (humming). It doesn’t get louder with speed and the pitch doesn’t change with speed. It’s a constant same humming. The only time the pitch changes and gets a little louder is when I make slight turns at higher speed (I’d say 1 to 2 degree turns). It shouldn’t be a chain because it doesn’t wine or grind with higher rpm. Thanks

Rotate the tires and see if the noise is still there. Tires with uneven tread wear or out of balance can cause a “humming” road noise.

It’s not the tires. Driving on gravel road creates the same kind of noise

But I did rotate the tires. Didn’t change a thing

thanks for the updates bro.

sadly we are only as good as what you tell us. seems the obvious things are not what you feel they are, so if you cant make a sound clip there's not much more your internet friends can suggest.

still wanted to make sure the timing chain recall was done...

At least you’ve got the tires ruled out. I had a similar issue two years ago, where I thought the noise was resonating from the driver side. It turned out to be the passenger wheel hub. Does the noise diminish when turning to either left or right while in motion? Or does it stay constant, get louder?

I will try to make a video clip

The only time noise goes away if I drive less than 5 mph. It’s constant, it’s always there. It does get slightly louder at higher speeds when I turn the wheel 1-2 degrees either direction. When I gain speed, the noise doesn’t change
