I've had vibration/noise issues around 40 mph while in top gear, I've noted accelerating forces a downshift, or I can manually shift to d3. Either action gets rid of the problem.
A brand new (2 weeks) Pilot with less than 500 miles. I am now hearing a clunking/thumping noise when I shift the gear from d->n and then in to r. This noise is not heard when shifting just from n->r. Looks like this noise is coming from under the hood. I didn't expect this kind of problem so soon in a brand new vehicle.
