general problems of the 2018 Chrysler Pacifica Hybrid

While driving on the highway going 70 going home after work the vehicle suddenly lost all ability to accelerate. I still had power, but the dash told me to press the break to start the car. I managed to coast off the bridge I was on thankfully and pulled off the side of the road. The car was stuck in park. I tried turning it off but it would only shut off for 2 seconds and immediately turn back on with the same problem. The vehicle was immobilized in park and would not shut off. The engine light stayed on the whole time. I had to call a tow to get home. The tow truck driver was able turn the car off and the car was drivable again but the engine light remained on. The vehicle is a 2018 with 5609 miles on it and have only owned it for 3 months.

My brand new 2018 Chrysler Pacifica Hybrid which I got on July 4th 2018 shuts off last week on a highway while I was driving from raleigh to charlotte about 70 miles/hr. With lot of difficulty we were able to pull over. I stopped the car and restarted the car, the car behaved normal but with malfunction indicator in my dash. Dealer is saying there was buggy software installed on July 3rd 2018 as a part of some u73 recall. Our family is very scared to sit in the car again. They are saying 2 parts damaged in car due to the buggy software patch applied, pcm codes p0420, p0430 - catalytic converter efficiency failure (both). Chrysler customer care says no issue with software, dealer is saying it's software bug caused the issue. I am confused now whom to believe. They said I will get my car in a month (may be). Very unsatisfying and feel very unsafe in this car now. Kindly do the needful.

While driving on a highway with a speed limit of 70 mph, a warning light came on that the battery was conditioning. I was then limited to 45 mph with very little acceleration, and the a/c stopped working. This was repaired, but happened again three weeks later when about to merge onto another highway with a 55 mph speed limit.
