Reported at 40,000 miles, April 2006 CrashInjury

Took car to mechanic for fuel pump work. He informed us that the engine cradle is rusted beyond repair and is un-safe to drive. I found the recall online and called hyundai. They informed me that remediation had been done in 2009. (a new hole for drainage had been drilled in the engine cradle frame and a sealant applied). Evidently this did not stop the corrosion of the frame and caused a weakening of the frame and a crack in the structural area of the frame. Is hyundai liable to repair this defect?
