Corolla Bouncing?

#1
I've just got a 2011 Corolla, and it drives strange (to me). I took it into the dealership and they don't seem to feel it. But it feels like some sort of bounce, or vibration from the front. It's as if the engine is improperly mounted or it's misfiring. It's not the tires because there's no pull on the steering wheel. The problem is I don't know enough about cars to really say what's wrong, or if this is even out of the ordinary. Hopefully you all can help me out with this!
