Of note should be the fact that manufacturers have the perception they don't need to maintain contact with the customers or notify them on a blanket basis of known or suspected issues. The cause of that has been 100% customer in origin. Had customers been a little more actionable when problems arose instead of lavishly providing brand loyalty things would be different now. Unfortunately what became evident to maufacturers was their customer base was highly sensitive to peer and adverising pressure instead of actual quality. Too much desire to be part of a "class" instead of dealing with reality.

The best engine ever made have not been made in some time, but the heavy advertisers, be that in paid printed media, sponsoring "super" pilots at contests, paid web media, or free advertising using shills forum discussions, did a great job of taking market share from them.
