However, had I kept the packaging & receipt and returned the failed parts to

Or do they just throw them away and keep making failure prone parts?

The statistics course I took was slanted toward engineers. Part of it
was an analysis of how many samples you had to examine to ensure only N%
of the output was junk. N was not 0% but was determined by the cost of
the QA operation versus the cost of replacing faulty widgets. That cost
was calculated with the assumption that at a given price point the
consumer wouldn't bother returning the widget.

Short answer: if making failure prone parts is more profitable don't
expect a change.
