Front Suspension Control Arm problems of the 2006 Chrysler 300C

I have had constant issues with the control arms, tie rods, and the door handles are all broken. I had to replace my radiator twice now. I love my car, but I am highly disappointed with the costs that I have had with this car. The radiator issues have come while the car was in motion. My engine died without warning while I was driving. I never had any warnings prior to the motor blowing. I have regular maintenance done to my car, but a new engine, 2 radiators, tie rods, and control arm repairs/changes seem to be the continuum for my car. The door handles are cosmetic and have not been repaired. I have records from my dealership and another place I entrust with my vehicle.
