Wife and I just leased Optima sxl and its been in the shop twice now. We have owned it a week. First problem was it lost power on freeway causing wife to get in the center median before getting ran over. Kia dealer claimed it was a throttle body actuator problem and needed a new part. Picked up car and very next day, upon startup, major shrieking noise like sire. Figured it was turbo and took it immediately to shop. Now they saying the turbo is bad and they are overnighting a new turbo. Wife and I love the car but never had a new car with so many issues. I've read articles on this forum regarding wastegate actuator problems. Have you guys hear of a turbo failure with a week old car? Dealer is really taking care of us so far but im hoping they know what their doing. Starting to lose faith in this car. Any suggestions or comments would be appreciated.
