2024 Lexus NX electrical system problems

I was in a car accident on the freeway . I had just got onto the freeway so I couldn’t have been going that fast . The brakes on this Lexus Nx [XXX] to say the least . Also the collision sensor and warning also are useless. The warning light and sound didn’t go off until I was basically rear ending the other vehicle . I had a different , 10 year old car . A 2014 that would start to pump air and brake itself even when the car sensor believed it was close to a car and I wasn’t braking .
