2020 Nissan Sentra forward collision avoidance problems

My daughter was driving her 2020 Nissan Sentra the other day and was trying to avoid hitting a dog that ran in front of her car she crashed into a park car. Our Nissan Sentra anti brakes did not stop the car nor make a noise before hitting that parked car. No warning from our car to prevent this head on collision. There is so much damage that our insurance has deemed it a total loss. By the grace of God daughter is physically fine but mentally she is not!!

After returning on 12/12/20 a sentra purchased on 12/8/20 - I swapped out with another sentra. Reason for return - aeb pedestrian light kept going on every morning despite varying weather conditions (warm vs. Cold). Received this car (gun metallic color) and on 12/13/20 - same thing happened! Will be contacting the service department tomorrow to request a replacement sensor. Could it be a faulty batch of cars at this dealership?
