general problems of the 2002 Dodge Ram 3500

Have a 2002 Dodge Ram 3500 that I bought new and the dash has disintegrated. The plastic is defective and has crumbled into a multitude of pieces. These pieces fly out of the air vents into your eyes and are sharp and will cut like a knife. This is a danger not only to my eyes but it I was to have a wreck they would fly and cut you. Have had to remove the pieces from vents that won't blow out that have gotten into the ac/heat door flap. I have never had a dash on any car or truck fall apart like this. If you just touch it it falls apart.
