I am glad you were not offended, then we can discuss this rationally. I am not sure your background, but my engineering background tells me for every failure, there is a reason behind, either some loopholes in your process or design. There is simply no such thing called stuff happens in the manufacturing environment. If you tell your boss that, probably you could just pack and leave.
From the follow up of the thread, it is very clear that it is not an isolated case (it again proves there is no such thing called things happen). It is a batch related reliability problem. There may be something wrong with their process. I am very sure given this high failure rate, Nikon engineers are alerted, know what is wrong and how to fix it. It is in the end Nikon's decision how to react.
As a conscious consumer, what I ask is simple: give me something worth what I pay for, regardless which brand it is. And if it is due to manufacturing fault, fix it for me. Don't charge me for something due to your fault. And I believe it is the ideal for all consumers including you. Yes, we may have brand loyalty. But don't spoil it.
I am not in the car industry, so I can't comment on Toyota's quality system. But i am glad Toyota admitted their mistake and did the call back.
