Transmission Failure problems of the 2019 Hyundai Tucson

My vehicle is equipped with a dct, which causes the vehicle to slow, hesitate, fail to maintain speed, and stop without warning. Further, the transmission causes frequent rpm surges, regardless of speed or terrain or road type (it is most frequent when going up a hill, but also happens on a flat road). When merging onto a highway on a hill, I must use the slow vehicle lane to get up to speed before merging into traffic. Often, I will pull out to pass a car and the transmission will fail to respond, causing me to slow rapidly. I have taken this to the dealership on multiple dates during the year I've owned and have been repeatedly told that it is "normal" and that it will "learn my driving habits. The latter is untrue, it does not learn and I need to adapt my driving habits to the uncertainty of the transmission. This is unsafe and puts me and other drivers at risk. On multiple occasions the vehicles behing me, regardless of following distance, have had to swerve or brake due to my vehicles failings.
