I drive a 2017 Acadia, the older style and I have to step up slightly (I'm 5'11") to get into the Acadia. I sat in a Telliride recently and slid right into it, no step up at all, I think even though it has more ground clearance then the GMC the seating entry/position is friendlier in the Kia. Not sure if you have but maybe try one on for size.
