I purchased my 2006 Kia Sedona from this business. Over the last year the car has completely lost power/acceleration while driving. Twice this occurred while on the freeway. The problems began at just over 20, 000 miles and the car is currently at 45, 000. This malfunction is obviously quite dangerous; luckily no one has been injured, yet. Following each event, the car was immediately taken to Kia of Lewisville to be repaired. They have attempted to repair the car each time, only to have the same issue recur. I feel that the car is not safe; I have no reason to believe that the fifth attempt to repair the car should have a different outcome than the prior four attempts. I want the car replaced but Kia Motors is unwilling to work a reasonable deal with me. They expect me to pay a hefty fee on the vehicle. Kia Motors and Kia of Lewisville should resolve this issue immediately.
