This noise existed since new but we decide to give sometime to breaking in. Since my wife drives local most of time and even if she drives on freeway, she does not drive above 70 miles so this whining noise wasn't noticed much. This Memorial weekend my family decide go on a road trip and I was so annoyed by this noise, I almost turned around after driving an hour. It was so annoying. I went to dealer for repair, adviser said he heard some noise from transmission but when he drove another Pilot, it makes similar noise. I drove and rode in many cars, I only heard this type of noise once from old rear wheel drive car. Definitely not acceptable from brand new car. Adviser said he is contacting Honda engineer for advice. We will see if Honda will come up with solution.

Update from Aug 31, 2020: My family went road trip again two weeks ago and again I had to dealt with whining noise , again.

As I explained before my wife doesn’t not experience this noise because of her local driving. Out of sight out of mind.

As soon as I came back from trip I took pilot to different dealer then last time and explains exact problem but this time technician didn’t even Boyer to take to freeway so “not able to duplicate problem “.

And this time I noticed whining noise doesn’t occur right away but has to drive high speed at least 20 to 30 minutes so harder to duplicate problem.

However, warranty is expiring soon so I am going back to dealer and complain whining noise I am experiencing so even after warranty expired I an go back until problem get solved.
