Our 2010 Honda Odyssey has been making a whining noise for some time now. It seemed to me that it was clearly the power steering pump. That said, I read this thread and then called the dealer. He did a VIN check on my vehicle and told me this:
“HONDA HAS EXTENDED THE WARRANTY FOR THE POWER STEERING PUMPS TO 7 YEARS OR 100,000 MILES SO BRING IT IN AND WE WILL REPLACE IT”
Thus, do not go spend money to get this fixed without talking to the dealer. When I have seen that people have spent money to solve this problem, I was surprised that I had not seen a post like the one I am making.
Good luck to those with a whining power steering pump.
