Years before they redesigned the part, they also sent key covers and service announcements to all the dealerships, although they made it seem like a minor thing, so the key cover distribution was sort of spotty. I'm sure this was the work of these two guys also. Uh-huh. And then you have to ask, how did these two guys know it was faulty and seriously so in the first place? Most likely, warranty repair reports. The key cover was the quick fix. When they got more reports, they redesigned it. Who handles the warranty and repair reporting? And when they get reports, I'm sure they try to test and repro - you wouldn't send out key covers to all dealerships w/o testing it at all, right? - who handles testing reported parts defects and the quick fixes (like key covers) to them? And when something spans this many departments, I do not see any way there are not at least some high level managers, possibly VPs or even higher, involved to direct the effort and approve the expenditures.
