Front Suspension Control Arm problems of the 2008 Hyundai Elantra

While driving I went to stop on a long downhill grade and suddenly a horrible metal on metal grinding sound occurred. The car swerved a bit and was hard to control. I was able to gain control and limped it home with the continuing extremely loud noise, especially when trying to turn, slow down or under braking. I was finally able to have my brother drive car to local mechanic very carefully and slowly and it has been diagnosed as having a broken left lower control arm. Local mechanic thought this might be an item covered under recall by Hyundai as he has seen a number of these issues. On investigating further on this site I could find no recall but did find a Hyundai TSB (17-01-038) that speaks to providing under body corrosion treatments for 2007-2010 Elantra's, for those registered in a salt belt state like mine. (new york). Obviously Hyundai realizes that they have a problem with under body components exposed to salt corrosion and is attempting to alleviate this problem after the fact. I was never notified of such a program and this defect is extremely serious as it can cause loss of control and a crash.
