How is it that your sister discovered this? The edge of the damage is quite fresh and clean so it was discovered right after happening. Did she hear it happen and investigate? If so, maybe she needs to recall the road on which she was riding. Rough road? Construction? Debris on road?

Since there is no evidence of external impact this should be a warranty repair but as it is damage, your sister should expect a battle. No dealership will want to go to bat for them with GM. If it turns out the damage is attributed to a missing bolt(s) on the flex plate they won't fight but there is always the possibility that there was a foreign object inside the bell housing (say an errantly dropped bolt at assembly?) that was never noticed (or reported). The proof will be in evidence of impact and / or damage from said internal foreign item.

In all cases, I wish her good luck. Please keep us posted.

Agree with everything except a bolt that dropped during assembly, that would have been heard during every startup/run cycle. One backing off the flexplate, yes. I would get it looked at immediately because if one was loose and backed out... i sure the rest will follow suit....

Yep. Also if you look at how that piece broke out, it looks like it was hit from the inside. The edges feather out toward the outside which wouldn't make sense if it was hit from the outside. And if it was hit from the inside, it was from something with force like a bolt coming loose while revolving in a circle at a high rate of speed. No update on this? I would think it's been looked at by now?
