general problems of the 2002 GMC Sierra

I did not know about this site and this accident happened in oct 2014. I was going around a curve with 40 mph speed limit and I was going 40 mph. I started to brake as this was downhill and a very large truck and I did not wish to increase speed as I followed the curve. My brakes did not respond and sank to the floor with no resistance. I had no steering ability either. I ended up in a head-on collision with a very large tree and the airbags failed. I split my head open on the steering wheel despite blocking my face with my forearms crossed; a DE-gloving 10-12 inch laceration down to the skull that wraps from my nose bridge around to my right ear in the circular shape of the steering wheel. My right leg was pinned into the center dash area as the engine block and steering column were shoved into the cab. I had to be removed from my vehicle with the jaws of life by emergency response teams. I am lucky to be alive. My quadrasteer was declared totaled by usaa insurance and destroyed without my knowledge. I called usaa 3 days after the crash after finding so many brake failures on this vehicle/year model and was told it was already destroyed, so doing an investigation was not possible. I have lived in pain and also paralyzing fear of driving since then; 3 years. I am a disabled military veteran with ptsd and prior brain surgery and this accident caused to me isolate so severely I could not even attend medical appointments due to my new fears of driving & riding in vehicles. My life is now ruined by this accident. Decreasing va disability due to inability to attend appointments caused a $1000. 00 per month loss of benefits. I can't afford my bills and have been struggling with the va to gain access to medical evaluations since they are now striving to cut benefits from anyone they can. Please recall now!!!!! who else has to be hurt or killed?????.
