 My car also is slow to shift from park reverse or drive to revervse. It also has been in the shop five times because something is draining the power from the battery that no one can figure out why. It has been thru two batteries and they put in a whole new fuse system... i drove it three weeks and the battery is dead again. They still cant figure it out so while it sits in the shop i have to borrow parents and friends cars because good ol kia doesn't provide loaner cars and i dont have the money for a rental. All this for a car i've only had four months!!!
