I wonder how many 'catastrophic' failures have occured? Just this one? 30? 150?
My guess is very few indeed. Sometimes, bad things happen to good people. Just like the current air bag issue. 50 or 60 million produced. A handful of problems. Lawyers get rich.
No product ever made, is going to be 100% defect free. No design in history has every been flawless. Chit happens. Sorry.
