2007 Chevrolet Impala suspension problems

Tl* the contact owns a 2007 chevrolet impala. The contact stated that the vehicle was taken to the dealer twice for concerns with the front suspension. The dealers were unable to locate of duplicate the failure. Late while the contact was driving 65 MPH, the contact crashed into another vehicle that was driving alongside him. The front passenger tire and suspension components fractured from the vehicle, causing the vehicle to go airborne and land on the fractured parts.

I purchised this car in april of '08 and it has been failing since I bought it. There is a vibration while riding in the car that makes your body bounce. The dealer states they don't feel it, but I have cronic back pain from it. I have had it at the dealer several times and no fix. I took it to an alinement shop they told me that the stuts were set out from the factory so the tires don't hit the grond flat like they should. The problem causes my tires to slip out of balance constantly making the vibration worse.
