The 7 speed DCT on the Kia Sonet HTK Plus model is a huge disappointment. There is a very significant lag in acceleration, and makes it very tough to overtake, Especially on highways when you have no option but to get around trucks. The time between hitting the acceleration pedal and the car actually accelerating is often enough to miss the overtaking window.
Even in reverse, it takes 7-8 seconds for the car to start moving by itself. It feels as if I am going uphill and have to hit the race pedal.
The 7DCT performance is quite bad, and no service person even accepts that this is a problem, simply calling this a DCT feature. They usually don't have the technical capability to either understand, or since they can't do anything about they just ignore.
All in all, a disappointing buy. I have to buy another car but have very low confidence on DCT now. But don't know if that is true for DCT in general, or Kia messed it up here.
Hope they solve this!
