Defective product claims are legally complex since, as outlined above, they have lots of moving parts. Victims are usually in a hurry to settle their claims, but no one else involved feels the same sense of urgency. Additionally, manufacturers often bury smoking guns, like incriminating internal studies or correspondence, if they can. So, if a case settles too quickly, the best evidence, and therefore maximum compensation, may be unavailable.
Most companies will take advantage of consumers if they can, just to make an extra few dollars. A defective product claim not only compensates victims. It also stops a large company from bullying your family.
