1995 Nissan Altima electrical system problems

I was stopped on interstate due to collison in front of me I was struck from behind my drivers seat broke backward, I struck the car infront of me and my air bags deployed, I was struck in the rear again. After the collison I cllimbed out of the car and immediately notice it was on fire. The fire began in the driver side rear of the car. My concerns are the seat breaking backward and the fire.

There is a major shortage in my car. The brake lights do not work right and when you brake only one side works, this had interfered with the internal lighting. Something is always wrong under the hood. You spend hundreds of dollars for them to finally fix the problem after they have replaced things that didn't need to be fixed.
