My daughters 2016 kia Optima is shutting off while driving. Sometimes it restarts after shutting down. Sometimes she has to hurry and put in neutral and restart as cars behind me don't know the car has shut off. She feels very unsafe and is afraid someone is going to run into her. Took it to kia dealer and they ran codes but nothing came up and they couldn't get it to duplicate. Happened two more times, took it in they ran codes with no results and updated the 1802 software. One day later it shut off again while at a stop light. Not always at a stop light sometimes driving 45 mph or turning a corner. This issue seems to affect many different kias vehicles on internet but there is nothing listed by anyone that has fixed the problem. Again my daughter feels unsafe and doesn't want to drive the car till it is fixed. This problem has happened about 7 times. I am showing the latest date below.
P1326 engine code came on while driving 60mph on the interstate. Luckily was in far left lane when engine shut off and was safely able to get off freeway to a nearby gas station.
