Can anyone help me out? Brought the car to the dealership and they could not make the car repeat what it was doing in the video. Transmission cracks under hard acceleration. It was previously at the dealership for a turbo replacement because the last one blew out and they had the car for three months. Got it back had it for 10 days and then it went back to the dealership because 3 out of the 4 spark plugs were fouling out and misfiring, now I have it back again and this is the new problem. Really disappointed in kia miss my 2015 Optima.
