This vehicle suffers from a hesitation during take off. According to Kia this hesitation come from a 7 speed dual clutch transmission(dct). Which causes the vehicle the driver to feel a shudder sensation. This vehicle has a double clutch. I have taken my 2016 Kia Optima dealers for repair to this problem without any solution. Runs rough.

When starting from a dead stop, the car hesitates up to 6 or 7 seconds. I think it has stalled, then it starts again by its self. This is extremely dangerous when pulling out into an intersection. It does this constantly.
