I see that you posted the same information on piloteers.org, and I find similar message threads on a lot of other message boards, both for the Pilot and the Accord V6 models that have VCM.
I wouldn't start with a lawyer, although a complaint to your local BBB is definitely a place to start.
I would also take it back again to your local Honda dealer, and ask them about this information I found on edmunds.com:
Good luck.The VCM is causing the vibration. A poor design and malfunctioning of it rear mount hydraulic comensator. This crazy little thing is supposed to counteract the vibrations by adjusting it's angle... In some vehicles it's misfiring and doing a bad job.
