Driving experience of Hyndai Creta

I have been using Creta for last 2 years and i am finding it very uncomfortable on long drives. I earlier had a honda city for 10 years and had done almost 1.2 lakh kms on it and never had a discomfort in long drive but in Creta its a major discomfort. I took it up with Hyundai but they claim that nothing is wrong and my experience is otherwise. I have done about 14k kms and long drives are really painful for the driver and front seat passenger. Any suggestions??
