2002 Mitsubishi Lancer suspension problems

Lower control arm on front passenger side of vehicle buckled under resulting in loss of steering control and the vehicle striking a curb at ~55 MPH. Dealership refuses to fix under warranty citing there is no proof that hitting the curb did not cause the damage. I was informed by the dealership that there had been a similiar incident the previous week involving another lancer. On this vehicle the failure was on the front driver side of the vehicle.

Having a problem with rear suspension. The entire back end sounds as if the frame is broken. Was assured by mitsu service that it is not a safety issue. I was told it needed bearings and bushings and parts are on back order. This is a 2002 lancer oz with 30000 miles this should not be happening to a car of this age. I am filing this complaint because I feel if there are two complaints on this site there are most certainly dozens more out there or more to come.
