I had my car taken in for the power steering motor not working a while ago. I had part # 19209136 replaced. Anyone know what this is?

Today my POWER STEERING light came on the DIC as I was pulling out of a parking lot and of course no power assist the whole way home. I don't see how this isn't a mandatory recall. http://www-odi.nhtsa.dot.gov/ivoq/index.cfm I filled this out and sent GM an email and I will call them...
