If I like the truck it wouldn't keep me away either, hell I bought a 6.2 GM with known lifter issues... though it turned out later to be much more prevalent in the 5.3.
Though I am buying an extended warranty on any vehicle purchase anymore as I did on my current.
I just think it's interesting that the engine failures keep showing up. It seemed like when Toyota announced the recall a lot of people expected it to expand to the hybrids at least or into later years. That has yet to be seen.
I don't always think quality and sales numbers tell the full story, just take a look at Ford, but you got to think the Toyota dealership are really hoping it was only the debris issue and it's solved.
