Not much experience w/ 'rods knocking'.. what would you say your symptoms were or what to look for? I push my car pretty hard occasionally with oft e85 tune. Just want to make sure I know what to look for.

I was in fourth gear doing about 50 MPH when I downshifted, accelerated, and heard a strange rotating rattling noise coming from the engine bay. I turned down my radio and the rattling turned into loud violent knocking. The car died in motion and I lost power to everything. Luckily it was on an empty Texas highway.

Let me just say if you had problems, you'd hear it.
There's nothing to "look for," it just starts happening when the bearing tolerances become larger due to oil starvation mostly. All that extra space between the con rod and crank will cause a metal clanking sound and will get louder and faster with more engine rpm.
That, or just a fluke at the factory.

This man speaks the truth.

It's a lease so I'm not worried about it. I do worry that it will happen again though.

What caused the failure ?

Car was somehow starved for oil and spun a rod bearing. The techs blamed it on my old 2012 factory tune. Apparently there was an ECU update that I never received.

Bottom ends don't fail easily. They're pretty much bullet proof at stock levels unless they are starved for oil.

True.

None at all. I've only had ignition coil failure in two cylinders prior to this.
