Engine Shut Off Without Warning problems of the 2016 Kia Motor Sedona

The persistent problem that we have had with our vehicle is the engine shuts down while driving, causing a serious safety hazard. The safety hazard is serious in that, while the vehicle is in motion, power steering shuts off and the brakes are slow to work. Each occurrence has happened when the vehicle is in drive and moving at a speed of approximately 20-25 mph. This has happened 3 times: - January 29,2017 - January 30, 2017 - February 16, 2017 the circumstances in each instance included driving and maintaining approximately 20-25 mph. Other factors are unknown. Fortunately, in each instance, I was able to pull safely to the side of the road and assess the vehicle. The first two occurrences, I pushed the start button and it was evident the vehicle starting system was acting unusual as it tried starting. The vehicle eventually started and I was able to continue driving. The third occurrence on February 16, 2017, I took kia's advice and did not attempt to start the vehicle and contacted kia roadside service. The second event occurred the next day on January 30, 2016 under similar circumstances. Again I was able to pull over without the power steering system functioning properly to a safe area and re-start the vehicle with the same uncommon sounds from the starting system. I called joe myers kia in houston, texas and explained the occurrences. On January 31, I drove the vehicle to joe myers kia for troubleshooting and repair of the vehicle. The vehicle has been to the dealership two times to address the safety defect. The first time was January 24, 2017 for 8 days. The service department could not duplicate the concern. The next time, it was towed on February 16, 2017 and it stayed there for 41 days. Kia did install a flight recorder to record all systems the second time the vehicle was brought in.
