Can anyone please help me with a humming/whining noise at around 45-50 mph. I used the manumatic mode and downshifted but the noise still occurs at the indicated speeds... not really sure what it is. TIA

We developed a sporadically occuring whining sound in our 09 MDX, which we initially only experienced at moderate speeds. However, this increased in regularity over time and under varying conditions. It turned out that our power steering pump needed to be replaced, which was done yesterday.

It may be a wheel bearing, have had all 4 replaced on my 08, known issue at the dealer.
