2024 Kia K5 POWER TRAIN,STRUCTURE,FORWARD COLLISION AVOIDANCE

I purchased a brand new 2024 kia k5 gt on September 2 2023; from kia of Cerritos "18201 Studebaker Rd, Cerritos, CA 90703" . My car has noticeable defects that affect the driving experience and can be dangerous. When coming to a stop the engine turns off as if it was deactivating one or more of my cylinders. While that happens it stalls the car. My adaptive cruise control doesn't work as intended since it came damaged from the manufacturer, while driving with the adaptive cruise control on the vehicle requires more input to maneuver. The vehicle did a sudden jerked and almost ran me into a freeway barricade. I also noticed some of my trim pieces and my steering wheel aren't properly put on and are falling off and the body trim is under recall. The dealer handlingthe recall is kia of downtown los angeles "1945 S Figueroa St, Los Angeles, CA 90007". I was able to fix the trim pieces by another dealer. I let the dealer I purchased the vehicle from know of the experiences I had with the vehicle and nothing was done.
