Being that this is a brand new vehicle, I would make an appointment with your local dealer. Ask to take a ride with one of the technicians. This may be the design of the transmission. You can show specifically what you "feel" to the technician on your test drive for verification.
Take it back to the dealer and have them test drive it with you so they can experience the problem. The vehicle is still under warranty

You're 2010 Kia is under warranty. I would suggest that if you feel there's a problem you have the dealership look at it.
The problem is going to be getting this to happen so that they can see it. If it's intermittent, then take note when it happens. The more information you can give them the better.
Of course it would be best if you could drive with a technician and show them exactly what's going on. If they can experience the same thing you do, they'll be able to help you or give you an explanation.
