Here we go again 140M DOWN

Hello everyone, Well last fall we took delivery of a brand new 140m for our sister shop, the other day after getting finished her third pm the operator was on his way to one of his roads on his route to be graded and he noticed a red engine alarm and a low oil pressure warning on the display he than immediately pulled over and shut down and called for our mobile mech, our mech arrived and did his inspection only to find the oil filter plugged with metal from inside the engine, NOT A GOOD SIGN!!! Low and behold we have seen this before at our own shop with our 140m, there were not any codes indicating any problems prior to the engine alarm, the pm was down correctly by our mech this is a major engine failure at 1500 hrs ours had a major engine failure at 900hrs both engines are c7's also I believe this machine had a injector problem about a month ago, Cat is going good for it as far as I know but now there's the down time which is costly, the amount of money that we pay for this product it should by all means be more reliable Cat has alway's been known as a quality product I run a 140h has over 10000 hrs on engine never touched still runs stronger than our new 140m with half the hours anyway is anybody else running the new m's having similar problems I figured Cat would have the bugs out of the m series by now, your thoughts on this issue are welcomed thanks everyone
