Brake Abs Warning Light problems of the 2018 Chevrolet Malibu

During operations while turning car locked up; lost power, lost steering. With engine running the radio and ac shut off. Drifted to shoulder of road. Illuminated dash lights: power steering drive with care, traction control, emergency brake, abs light, temp showed cold, no gear indicator light. Operated car less than 5mph approx. 1/4 mile and shut engine off. During operations it sounded as though brakes were on (screeching/clanking). Once engine shutdown stabilitrak light illuminated intermittently with power steering. Doors would not unlock, windows would not go down (trapped in vehicle 10 min). Brake pedal locked, car would not start. 45 min later car started. All illuminated lights cleared, check engine light illuminated. Vehicle towed to dealership. Dealership investigated. Several fault codes were present. Each fault code pertained to vehicles communication. Vehicle lost communication with everything. Dealership stated difficult/impossible to follow any sort of direction for fix. Dealership drove car and could not replicate incident. Asked me to drive and recreate problem then to bring back. Car is unsafe. Instantly locked up during operation, trapped me inside, left me stranded and scared me. Refuse to drive. Gm was contacted; awaiting guidance.
