manufacturers usually determine warranty requests such as these as being either the result of a factory defect, or some type of neglect, abuse, or damage
in this case, your corrosion issue would probably be considered "environmental damage"
what kind of shape are the body panels, fenders, and the sheet metal beneath the hood in?
if the frame is the only component affected by the corrosion, and there is no evidence of similar corrosion elsewhere, then the frame itself may be considered defective
if parts other than the frame are affected, then the damage would almost certainly be considered environmental
