general problems of the 1998 Lexus GS400

I was driving down the street, a rather busy street trying to stop. The Lexus would not stop, due to the struts and mounts are broken. Which I learned from sears automotive. The defects interfere with car overall ability to stop properly, it also sways over into the opposite lanes. Because the car wouldn't stop properly, I was rear ended, by another car that was going about 35-45 miles per hour. The driver told me that he thought I was at a complete stop. I now have severe back and head pains.
