2019 Chevrolet Equinox electrical system problems

While driving home from work at 9:30 pm on a state highway, my 17 year old son hit a deer on the front passenger side of the car. The airbags deployed and he slowed down and pulled over and smelled smoke. He got out of the car and saw flames. He immediately called 911 and his mother. The car was on fire and burned until fire company got there and put the fire out. Most of the passenger side of the car under the hood was destroyed. The car was a total loss. My concern is that car should never have caught on fire.

Purchased new car on september 7 2019. Started having car issues on 9/25/2019 took car in on 9/27/2019. Car was making loud screeching noises, brake pedal would get hard. Was hard to break. When reversing screeching noise would get louder and louder. Was told by a chevrolet technician car was fine it was because it was new. Took car in once again on 12/26/2019 vehicle would randomly not turn on, brake pedal would get hard, car would screech.
