I had just left my home and got up to about 20-25 MPH when my Jeep Wrangler Willys 4XE suddenly and abruptly came to a full stop causing the tires to lock up as well and screech to a stop then it shut down and I had to restart it. It jolted my upper body and head forward and couldve been much more dangerous if I were on a busy road or if anyone were driving behind me. I took it to my local dealership and they were able to recreate the issue after driving it and it shut off just as it did for me. They brought it in and seem to have primarily done some software update but didnt express much confidence in the repair. They just said there were no DCTs but there was some software updates and that should fix it. They also claimed there were no recalls present on the vehicle which is even more scary. So the only way there fixing this if they even are fixing it is it already happened to you and put you in danger.
