Transmission Stuck In Gear problems of the 2016 Hyundai Tucson

Acceleration issues from stop. Engine will go to high rpm's without moving the vehicle. Issues seen with vehicle leaving 1st gear, vehicles rolls in to intersection and loses power. Vehicle has hard shift issues and often seems to be "stuck in gear" for too long.

About mid-may of this year my husband experienced loss of acceleration (as if in stuck in neutral) at a red light. The car was in drive, the car revved to 3500-4000, but the car rolled backwards. The car was without power for about 10 seconds then terrifyingly lurched forward as though slipping in and out of gear. We took the car to the dealership on 06/21/2016 and were told that our car needed a software update and all the adaptive values were reset. We took our Tucson back. On 07/07/16 in rush hour traffic, our Tucson lost acceleration/power again when pulling away from a busy red light. The engine just revved up to 4000+ rmp, rolled backwards and had no power or forward acceleration. The car was in drive and the loss of power was about 20 seconds. We immediately called our dealership service advisor and were instructed to bring our Tucson in immediately. Our car was kept for several days and on Monday morning, July 11th I received a call stating that the technician was unable to replicate the loss of power and no error messages were identified and "that was just how the dual transmission (dct) functions". I picked up my car, drove about two blocks away from the dealership and lost all acceleration/power again when attempting to turn right onto a busy street from a stopped position. This time the loss of power was a full 45 seconds or more. The engine revved to over 6000 rpm and sputtered, slipping in and out of what felt like neutral, it was terrifying and I was almost hit! I immediately returned to the dealership and demanded that someone test drive with me but unfortunately it did not replicate the issue. I was told that the service supervisor would be looking at my car. The loss of acceleration/power is a very dangerous problem and we do not feel safe driving our Tucson. The dealership seemed completely at a loss as to what could be the problem.

There is a problem with the 1. 6l turbo dual clutch transmission. On three or more occations, pressing the accellerator after being at a couple stop at a traffic light resulted in the vehicle revving to the redline and the car not moving. The last time it happened (June 18th 2016 ~2pm), the car began to roll backwards because I was on a slight incline. I almost hit the vehicle behind me. I tried tried putting it in park. I tried switching to manual mode. I tried turning the car off and on. Nothing worked. It would not move. It was as though it was stuck in neutral. Then without reason, it began to move again. When it did move, it was extremely jerky and lurched forward a couple of times. That was the worst and most frightening. Lately all it has been doing is once or twice a day on average it does the slow acceleration and lurch. This happens during my morning and evening commute. Once it has happened, it does not happen until the next day. I have been lucky that it has not happened while turning into traffic. But it is clearly a dangerous situation.
