Brakes Failed problems of the 2020 Mazda CX-5

Bought a Mazda cx5 June 2020 and it was involve in a accident sept 17th 2020 do to brake failure. My mother was driving the vehicle and attempted parking in a apartment complex when the vehicle failed to stop and collided with the facility 20ft in front of the parking space. At the incident, I the owner, found 3 damage rotors were the flaw came from heavy grinding at the caliber (see attach photos). Within the caliber's alloy you can also see the chipped alloy produced from a flaw & the alignment of where it grinds the rotor (see attached photos). A witness stated she was present during the time of the collision and a police report was take from the witness. I can provide plenty of more pictures and videos to explain the geographic and demonstrate via video the flaws at the collision. I've attempt contacting Mazda four times but they continue to placed the blame on me "for bad driving damaging items they consider tear and wear products (rotors and calibers)" I explained I only had the vehicle for 3months and its three rotors with similar damage. Yet they told me my insurance must find them at blame. My insurance appraiser stated they will not go to that distance; they just fix or pay off the loan. I am fustrated! you all are my last hope! going through my insurance will cause me a deductable and at fault blame. Going through Mazda is insulting their product, yet I find this frighting but it's their responsibility to conduct further research to why the rotor/caliber went bad in such a short span. Explaining! even if I am to be blamed, for the incident. What about the product? I only owned the vehicle for three months. Within a little over 3,000 miles. Please help.
