I have had the vehicle for about 3 months and have repeatedly tried to resolve a vibration/buzz in the vehicle.
There was a vibration at 65-80mph in the steering and frame.
There is a buzz when driving at any speed above 55mph.
For the vibration I had to take it in 4 times and they were finally able to get rid of most of it. Replaced tires, and doing a RoadForce balance.
There is still some vibration at 80mph.
The buzz will always be there. Honda USA representative (customer service) said that "is characteristic for this vehicle".
Take away from this, if you have your heart set on a Pilot, take it for an extended drive and make sure that you can live with these symptoms.
