2020 LINCOLN AVIATOR Forward Collision Avoidance Automatic Emergency Braking Problems

I don't know the component or system that failed but sometimes when I am parked and put my car into reverse, the brakes lock up but my car will roll backwards. I have to either jam both feet on the brake pedal or quickly shift the car back into park and turn the car off and restart it. This usually will correct the problem. It feels like the brakes are locked and they are really hard to press. I drop kids off at school and this has happened in the parking lot several times with children walking behind me as I am getting ready to leave. I no longer am able to pull in forward to spots and have to back in to avoid reversing with people/cars behind me. I would rather hit a curb then potentially roll into a person or another car. I've taken it to the Lincoln...

Pre collision assist warning, service advance track, 4 wheel drive fault all these codes showed up at the same time. Also the cheap fabric liners in the wheel wells are tearing under normal driving conditions

My warning light stating a AWD malfunction has occurred has gone off 4 times, along with warnings for malfunctions in precollision assist and hill climb assist and the light has come on 4 times for each of these. When driving these lights come on and when the AWD malfunction light comes on the car drives very loose and I do not seem to have firm control over the steering and i feel like the car wants to swerve and I do not feel safe driving .
