2002 Subaru WRX Steering problems

Control arms were recalled in 2011 for rust issues and failure on the hanger brackets. Got the parts checked at the time of the recall by a certified subaru dealership, the dealership sprayed a "rust proofing" agent on the control arms. Three years later I was driving down my road and lost control of the vehicle completely. The driver side lower control arm had rusted through and broken at the hanger bracket. Subaru of america will not cover the repairs as the recall had been performed already (even through it did not prevent the issues from happening). *Js
