Power Steering Pump problems of the 2020 Kia Motor Telluride

My 2020 kia Telluride has had electrical problems since 3 months after purchasing it in June of 2019. It started out small with my backup camera glitching/not being visible, the interior lights flickering, and my heat not working properly. Then, it quickly escalated to multiple emergency lights engaging in my dashboard while driving or stopped. I called the dealership and was told if the codes aren't active they can't service the vehicle, so when it happened again I brought it to them directly. At this time my vehicle wouldn't go in reverse and the steering wheel locked. The diagnostic report stated the car lost communication with fuel pump control module, instrument panel cluster (lpc), control module (ccan),and hvac control module. This happened on two occasions compromising my family's safety. On the 3rd occasion, the following happened: the steering wheel locked, shifter wouldn't work, no lights next to shift, wouldn't go in reverse, no backup camera. On the 4th occasion, the following occurred: warning lights/emergency lights on dash, steering locked, no lights near shifter, steering tight, rpm indicator went to zero, speed went to zero, warning lights switched on an off to different ones. The dealer replaced the floor harness, dash harness, and engine harness. Even after these "fixes" it continued. On the 5th occasion, the emergency lights came on and my vehicle shut off while driving and I lost my brakes! the following occurred before the shut down: forward collision warning light, emergency light, rpm indicator up and down, abs warning light, degree/temp light flickering on and off, plus a few more warning lights. This time my car had to be towed. Kia will not take the car back and denied my claim after supplying over 70 pages of documentation. My car has been in the shop for a total of 84 days since October 19, 2020.
