Cars from the Zilina, Slovakia plant are transported, usually by train, to Cuxhaven. There they are loaded onto a DFDS roll on roll of ship, usually two ships doing one daily run. The ships are mixed cargo, trailers, lorries and vehicles. From there they go to Immingham, where they are offloaded and transported the short distance to Kia's import facility at BCA Kia, Stallingborough. They are then given a pre-delivery inspection and wait to be allocated to a car transporter that is delivering to your area.
The shipping process can take anything from 2 to 4 weeks on average, however I've seen members wait longer, so don't quote me if it doesn't arrive in four weeks.

Edit: You need to take into account the Christmas/New Year break is coming up and this slows things down. Also some manufacturers are holding back deliveries until the new year in attempt to meet the governments net zero targets, although I don't know if Kia are doing this.
