Front Suspension Leaf Spring problems of the 2008 Toyota Tundra

Leaf springs giving out, never put half of the max weight capacity, called Toyota they told me nothing they can do and they stand behind their product even though I personally know someone that had theirs repaired at no charge Toyota would not fix it for free if they did not know the product was bad and faulty. Noise coming from front end of vehicle while driving between 10 to 30 mph. I was told needed entire new front end, and other components for the repair. I did not know Toyota did not care about the public so much to let unsafe vehicles to be out on the road. Cannot drive vehicle until these repairs are done for worry of safety for me and my family.
