I rented this vehicle and I expected smooth transitioning through gears, especially noticing it was a 2015. There were less then 10,000 miles on the vehicle. I am unsure why the car responds quickly one moment and the next it seems I'm having to punch it to move. I wouldn't suggest purchasing this vehicle with difficulty shifting with regular maintenance performed and under constant inspection; the place where I rented it has a legit car shop and dealership car shops surrounding it. I have not noticed any evidence of a leak in transmission fluid.
