Driving VA Interstate 64. Traveling right side travel lane approximately 70 mph. Had ADAS engaged. Car entering highway, moved to center travel lane to pass. As I approached entering highway car, suddenly, my car stalled, engine off and I was stopped in center travel lane. Able to start car by putting transmission in park and pressing start button. Called KIA Car Care Center - They have no record of this type situation occurring throughout country. Took car to dealer. Their Technology Service Rep checked whole system and found no problems including memory bank listing the stall/stoppage incident. I will go to dealer and ask for their report. 2nd incident. Happened within first month or ownership 10/23. I dismissed incident as something I must have done due to my lack of familiarity with new technology.
