If i slow down then speed up it takes off slow. if i go up a hill it putts and when i drive it just feels like its puttering the whole time. took it to dealership of course they didn't find anything but this is a new car i know something is wrong. i just got the car in march drove fine no accidents or anything and it's kind of disappointing that my car is like this but know one knows what's wrong.
I have had this vehicle for a little over two months. it currently has 1600 miles on it. the transmission was replaced once and i am still experiencing studdering and shaking. have another appointment on 3/15. even have kia customer service involved.
