Strange throttle issue

I recently picked up a 2013 r-spec turbo that has 103k miles. It runs really well except for 2 issues im having trouble finding info about. I noticed startups can be a little shaky for the first minute or so, almost like a missfire but no codes are coming up, the second issue which I believe is connected is that when im driving and I give the car gas to stay at a steady speed it bucks, but only when im very lightly on the throttle, once I get past that small point it has no hessitation, its very annoying because i have to constantly come on and off of the throttle to stay at a steady speed. Any ideas?

I don?t have a genesis but I have a 2017 sonata limited 2.0T, I have the same hesitation and light bucking when very lightly giving it gas. It?s almost like the computer gets confused and causes it to misfire. It?s not a huge deal to me and no one else has mentioned it, but it does concern me what might happen further down the road, say 50-75000 miles.
