Could be a few things. No check engine light? If the check engine light is on, you may have an engien that is misfiring, and not running correct.
Otherwise, it could be a problem with an engine mount, exhaust hitting the car, or something weird like that.
I'd put the car up on the hoist to check for damage, like if you've driven over something that's done damage.
where do you feel the vibration? Maybe get out of the car (with it safely in Park), and have a listen around the car to see where its coming from.
Better yet... your car is just over two years old. WARRANTY! - bring it into the dealer.
