2005 Nissan Titan brakes problems

I was driving on route "a" state blacktop coming into a sharp corner and when I applied the brakes the front wheels began to shimmy very hard. It caused the 2005 nissan titan pickup to lose contact with the highway causing it to leave the road and overturn. The truck was totaled and I received minor injuries. Air bag and seat belt saved me. Nissan knows they have a problem and I was not notified about a possible brake problem until it wrecked me.

I own a 2005 nissan titan pickup which I drive mainly in the winter due to my job requiring me to go into work in every snow storm. I have only 128,000 mi on my truck. The truck sits in the summer to save on gas. After the truck sat for three months this summer had to change a leaky oil pan from rust. Once that was fixed I took it out to ready it for inspection. While driving came to a stop sign brake pedal went to floor. Tried pumping pedal and had no brakes at all.
