hate the kia sportage

I will never buy a kia again. We bought the car second hand at a landrover dealer with 68420km an now has 77000km on the clock. We had the car in and out for repairs almost each month we had it. The car simply loos power. Dead as a doornail. Eaxh time we take it toe kia paarl and then it work fine for a month or so and then it just do the same thing. This time its real bad. Black smoke coming out it you pull away and no power. This is the kia sportage. Stay away very far away. We are nou stuck with this stupid kar and warrenty is almost over.
