NHTSA Complaint #11510054 — 2009 HYUNDAI SANTA FE

While I was driving home, I went to make a turn and I heard a cracking noise and it felt like the steering wheel went one way and the frame was going the opposite way. I drove very slowly to a service station and when they looked at it they said they couldn't believe I drove the car without getting into an accident, they said the car was undrivable because the frame broke, They went on to say it was due to rust. I'm a 2nd owner and when I called the Hyundai corporate Headquarters they informed me there was a recall #947 Santa Fe underbody corrosion. I was told I should've received the recall when I received the new registration, I never received the recall, where do I stand with getting my car repaired, is Hyundai responsible to do the repair, I left a message with the service group at the dealership and haven't received a response yet.
