For more context, I was 99% sure they there was an issue with the component and that a hardware rework would have to be made sooner or later. The systems architect had some seniority over me but I could have pushed the issue hard enough for it to be addressed.

Then I did not take the high road. The guy was very obnoxious and I had other issues to address. So I let it slide to maintain my "this is important" quota for other matters.

And a couple of months later, when some units failed on the test aircrafts (I insist on the fact that this was not a critical system), I had an issue report showing that the issue was observed during supplier-side tests and then ignored.
