I've seen and repaired cooling system gasket leaks on psi engines that weren't even broken in yet. Not a lot mind you, but more than one. I'm not impressed with the quality of the gaskets. I've also found radiator hoses not tightened properly from the factory. No fuel system trouble yet though.

I'm not a fan of anything Mitsubishi based in this industry. Hopefully my mind will be changed over time, but I'm not holding my breath.
