Quality Engineering and Construction from Wally World
Had this beauty roll into the shop on Saturday. Wanted to know if we could fix it.

Not sure what I'm looking at. Looks like a suspension pivot? Which tube broke out? You know the famous WallyWorld guarantee:
"if it breaks, bring it back and we'll replace it with another just like it."

Thanks cyccommute, that gives me a better idea of what I was looking at. No way the tubing should be that thin in that spot regardless of how good/bad the weld is.

Looks like the bracket holding the shock mount was welded to the tube, and the weld weakened the tube wall such that it tore out. I don't think it was cut by the manufacturer, the tear is in the shape of the weld.
To OP: I hope you immediately told them you couldn't fix it, or quoted an FO price of $4000 or something.

Feature, not a bug. It's the optional spare pencil storage compartment.

It's obviously poor engineering, because a failure like in the OP is bound to happen when the rear shock bottoms out hard.

I'm guessing they skipped that step, or simply don't do it when they are cranking these out of their factories.
There is a spec that we use in the aircraft industry that the shops must follow, or bad **** happens.

But what kind of chain lube was on the bike?
That makes all the difference.
