I have the Forte koup sx tgdi trim. I was driving on freeway at 75-80 mph. I noticed I was not able to gain enough speed to pass slower traffic. Also noticed that once speed slowed to 65-70 mph the was no power when trying to accelerate. However the car still was able to regain speed and maintain once desired speed was reached. I then heard a noise when accelerating. It sounded as if something was binding up. I assumed it was the turbo. I pulled off an exit shut the car off. I let the car sit for a minute and then started it. The engine seemed to be louder than normal. I put the car in drive and could hear the noise in the turbo again but it was not as if something was binding it was it was loud air. I drove approx. 1 block and noticed smoke. I pulled over shut the car off and looked under the hood walked around the car did not see any smoke from anywhere. Turned the car back on, no smoke, engine was quieter, drove another block and began billowing behind the car the engine at this point came on. Pulled into a parking lot shut the car off and did a walk around. White smoke was coming from both exhaust pipes. Had car towed to Kia dealership. They have had the car over a month. Spool on turbo flew off and oil was sucked through exhaust. The no warning lights has been explained to the failure of O2 sensors, turbo spool, and some part other being off balance to all happening simultaneously. After a month a picked the car up and have aprox 80 miles and the engine light is on. Dealership service said T is from oil burn off and nothing to clear it. My display for rear camera is not working and no eta for part to be available.
