this is classic - vendor supplies samples to win the bid. they are tested and no issues. then sends 2500 of them that have 10% yield failure.

If I recall correctly, CC is already using some of the best FETs out there. FETs aren't the whole story though, as you know.
As for the BEC chip, I have no idea what they could do better (other than improve it).
