N,
#1 It is not a rant, it's a discussion, if I was actually ranting it would be very obvious, trust me.
#2 I am glad to hear you are familiar with statistics, thus you should know why this is not a sample set of 5. You can also consider following: What is there to assure us sample set it not much bigger but we just didn't hear about it? What makes you confident that we didn't hear about it because owners do know how to test for it, did test it, and it did pass the test? Could it be that people are having them without being aware there is an issue? Wouldn't be the first time.
