It could be a variety of things, like maybe the wheel covers were just put on loose, but be very cautious, as the wheel lug nuts may not have been properly tightened. This is not unheard of after a wheel rotation. I did it myself in fact and ended up driving down the road with a wobbly wheel on my Corolla. It's important to have this checked asap. Avoid any high speed driving until then. If you notice any sensation of the wheels wobbling or rocking, pull off the road immediately.
One thing you could do besides checking the lug nuts, take a look at the wheel covers. Are any of them on loose? Are they different from the right side to the left side? Maybe the wheel covers are not symmetric and need to go on the correct side of the car. I've never heard of right handed wheel covers, but anything is possible now-a-days.
I think some Kias, not sure about the 2013, may have front disc and rear drum brakes and that might be what you are noticing, how the front and rear look different. In any event, even if they are disc both front and rear, the front wheel mechanics look different than the rear b/c the front wheels power and steer the car, while the rear wheels are just along for the ride.
