What could cause this bent push rod (not a Mopar, but still…)

Not not a Mopar, but a general engine question. Posting here because of the wealth of collective knowledge in general.

Last week wife was driving through the neighborhood collecting kids for carpool. 2018 suburban with 6.2 with 58,000 miles developed an engine noise/valve clatter. Truck gets intermittent usage, hence the relatively low miles.

Truck towed to dealer for warranty service. Valve clatter traced to bent push rod. Pictures below.

Tech reports no damage to lifters, rocker arms, or camshaft (camshaft inspected with camera while engine in car).

Service writer think this is just bad metallurgy and random failure; can’t find any other cause for damage (and they will get paid by the warranty company for anything that they can verify is broken and needs to be replaced).

I am worried that this problem may replicate itself again in a year or whatever, after the warranty has expired.

Thanks in advance for sharing your thoughts.
