2017 Kia Sportage slow speed hesitation

I have had a problem with slow speed hesitation since I bought the car. It started telling me I needed service since it had ???Where did it go!!!
.around 17…that is a bummer. I should have taken the car
back, I live in the mountains and it just is not convenient to go there and sit for hours. For the small amount to service they gave me…changed my oil and that part I was there for 2 1/2 hours. I know that SERVICE is the bread and butter of an agency…will I go there again, probably NOT.
WHY ARE TAKING OUT WHAT I AM TYPING!!! AND CHANGING WHAT I AM SAYING
There is plenty of space below,SHAME ON YOU!!!
You took out everything about my NOW terrible gas mileage…I will not retype it all
From 23/24 miles a gallon to…17/15…A few times has been as BAD AS …12 MILES A GALLON. This is really great!!!1 Serviced at 46?? miles…currently have 6000
Purchased…8/13/17

It will even more inconvenient sitting on the side of the road waiting for the tow truck.
