Since there are no readily available recalls on the issue, we have to assume this is a rare problem. The question is the roads and the way the car is driven. If the links were broken to begin with, they could have allowed too much side-to-side motion, which would attribute to premature wear on the shocks.
Something to remember about shocks: They are like your eyesight they gradually deteriorate to the point that you may not notice a problem until it is so bad that it is a serious problem.
Mileage has a bearing on the issue as well. But, it appears to be a rare condition that a good technician can fix to a point you should not be overly concerned.
