From the company's point of view (purely pathological) the 'cost' of the injuries would be damage to their brand, lawsuits etc. That should be taken into account.

Ethically though I think the recall was the right thing to do. And presumably the sooner they do it the better for everyone?

Another interesting 'risk' to look at is given some evidence that your product may be defective, what is the probability that is actually is defective (upon further tests). And whether to test 'under the radar' or be transparent about the problem. (Putting ethics to one side for a moment).
