I had a Civic that I bought about 15 years ago that had some slight little issues. My dealer wasn't much help initially, but after speaking with Honda North America, they handled it very well. Now on some vehicles there truly are noises that are "characterstic of the vehicle" and there's no way around it, but it seems that a whine in a Honda like this would be something that shouldn't be there. I can't imagine the Acura ZDX making the same noises, especially for what they want people to spend on it, and the drivetrain should be the same.
