In at least 3 different drivers experienced the engine shutting off while driving at low speeds. It happened either while stopped at the traffic light, or shortly after being stopped at the traffic. The engine stalled and the message on the dash said to stop the vehicle, turn it off, then turn it back on. Fortunately, we were able to coast to a stop and follow the procedures. We replaced the fuel module and fuel pump, which did not help. I did some research last night and found an article from CBS News dated 01/12/2018 for this issue that recalled some of the Pacifica minivans starting with the 2017 model. Our van is a 2018 Chrysler Pacifica. I suspect it was built AFTER the recall, but the software was not fixed when built. I want this fixed under the recall umbrella so I don't get charged for something Chrysler already new was a safety problem.

Our engine has stalled while driving the vehicle at least four times since July 1. The engine begins to shudder, and the car will not accelerate, and then the engine completely dies. After it happened today, it was not possible to restart the engine or put it in gear. My and my family's safety was put at risk because the vehicle was inoperable. Three times this happened on major interstates with traffic moving at high speeds. I had to move my children and their car seats into another vehicle while traffic passed. We have had the vehicle in for service at least three times, at least twice at Chrysler dealers. The problem has not been reproduced (yet) but this latest time it completely disabled the vehicle so expect they will see more of the problem now. After the engine cuts out, we get an electrical warning light that flashes briefly, plus a check engine light, and a message that instructs to move the gear shift to P to start the vehicle and another that warns that the Start/Stop system needs service. We have had these all serviced, the fuel pump and battery replaced, and have been told the problem is resolved and yet it keeps happening.

While driving straight at highway speeds, engine started hesitating, quickly followed by engine shutdown and total loss of acceleration. Within several seconds engine restarted, followed by a rapid increase in rpms. Then engine shut down again. After pulling off road, I waited several minutes and restarted the car. It would run for 30 seconds or so and then shut down, this pattern repeating until I could find a safe spot to park the car and arrange for tow. Dealership replaced fuel rail pressure sensor, fuel supply tube, and fuel pump. Car is 6 months old.
