Tows what to get that milage???
We have a client that only gets that empty and when he tows his 2 ATV.s it drops to 9/10.
And a Yota full size gets 16 new and empty.

My dad's 2010 4Runner dropped a valve into the motor with less than 5K on the clock..
Every manufacture is going to have bad parts in a given lot.
Toyota pretty much invented AQL and every major manufacture uses it today regardless of what they are producing.

Personally I would have made Ford take it back and switch me out after the 2nd one popped.
I read a few forum posts from other forums, says there is an issue with the "charge air cooler". Seems it cools too much causing condensation, then gets sucked into a cylinder causing "hydrolock". I'm guessing water in the cylinder blows the connecting rod through the block... http://www.tundraheadquarters.com/bl...oss-limp-mode/
The thread I linked has been closed at that forum. No reason given.
Those MPG were with an ATV or motorcycle in the bed and loaded cab, or empty.
Towing it is 9-11mpg.

With them replacing the engine, you have to wonder, if they replaced everything to eliminate any chance of debri contamination from the previous failure. Also, are the owners using the correct oil for the engine, or merely going to jiffy lube? One problem with direct injection engines, there is nothing to keep the intake valves clean, since fuel doesn't wash them down. I've seen some ford, well mazda cx7(same engine as the ecoboost 4 cylinder) with coked up valves to the point it would not run. Separate issue from the 3 blown engines, but something to keep in mind.
We're talking about ford here, for gods sake they can't even design a spark plug, look at the 5.4
Got to love those stupid spark plugs.
