My Ceed always jerks in the city traffic or in the traffic jam at low speed, no matter what the gear is in. As soon as you tap the accelerator pedal, the car jerks; if you release the pedal again, the car jerks again. You can compensate for that if you still play with the clutch. But that’s annoying in the long run. You might think it’s a beginner. Of my 7 cars before, no one made such bitches – and that’s the latest one so far. My Kia dealer has in common t, that’s normal and you can’t set anything. Just for information – the whole thing with the air conditioning switched off and even if the ISG is off.
