2019 Subaru Forester forward collision avoidance problems

Driving down a side street I pulled into a parking space behind another vehicle I hit the brakes and instead lurched into the car in front of me. I pushed the vehicle in front of me about 8 feet and finally came to a stop. During this time I repeatedly pressed the brake pedal and had no response. After having the car repaired at the collision center they brought the vehicle to subaru. Subaru ran a diagnostic test and said that there was nothing wrong with the car.

Windshield cracked sometime between 2/16/21 and 3/4/21. Vehicle was purchased as pre-owned certified on 2/13/21 from dealership. Came out to go to work on 3/4/21 and found large crack across windshield. I had no instances of objects hitting windshield while driving that would have caused initial crack. Internet search revealed numerous subaru owners complaining of defective windshields in model years from 2017 - 2019. Cost to replace windshield and recalibrate eyesight feature expected to cost in excess of $1,000.
