Timing chain tensioner gave out on a '07 Altima in Phoenix traffic last July

I was sitting at a light on the I-10 frontage road when I heard this rattling noise that got worse as I accelerated. Pulled over, popped the hood, and the chain was slapping against the guide. Had to get it towed to my buddy's garage and we spent the whole weekend pulling the front cover and replacing the tensioner and chain. The plastic guide had shattered into pieces, some of which were stuck in the oil pickup. Has anyone else seen these M9R engines eat timing components this early?

Man, that plastic guide crap is unforgivable.
