Front Suspension Springs problems of the 2000 Lincoln Navigator

I purchased a 2000 Lincoln Navigator from laurel-Ford dealer in mississippi on August 21, 2003. After asking the dealership if all necessary maintenances were done on vehicle my family and I left for new york. I still had the original mfr warranties and I purchased an extended warranty plan. While traveling on the interstate on August 25th the brake lights came on and suddenly the left rear tire exploded. My family and I feared for our lives. It turned out that the brakes were faulty, no emergency brakes, no stablizer, heavily rusty links, and etc. The tow truck had to tow us twice. After ariving in new york, a dealer, told me that the vehicle was never serviced. They explained in detialed in wrting. We could have been killed. I was on vaction with my twin boys and wife. I very angried with the laurel-Ford dealership in ms and its owners. The tires seem dry rotted and corrosion was very visiable under the SUV. Since then, I spent over $5000 getting this Navigator fixed and got very little satisfactin from the owner and his dealership.
