Hello. Depending on the road you are driving on and if here is extra weight in the vehicle then this can occur. This is usually compensation for the lack of power that the engine puts out. With that being said it should be minimal. If it is very noticeable then you may actually have a programming issue or a faulty throttle body. Both are common on this vehicle. It sounds like the vehicle is still under warranty so I would take the vehicle to the dealer.
