Who knows where Mitsubishi cut costs, though.

Does the engine use a timing belt or chain? Belt is a deal killer.
I have had plenty of harmonics go, our "bad" 6.2 diesel broke its crank after the harmonic flew apart at 200k.

Our 350 had a "pulley" off the bottom that drives the serpentine hammer and was also akin to a harmonic going (same location as the 6.2)

One of our old fords did this as well.

So I will say it depends on what they have the harmonic doing, if its integral to the serpentine pulley or fan drive it will go rather often, if its totally independant it will likely last just about forever.

Ours tended to blow a piece off and die catistrophically.

Yeah and I agree on timing belts, they really suck.
