The effort needed to remove them makes me wonder as well.

Yes... I worked in a bike shop in the 90s and we'd get the occasional brake typically at a joint. It's why Vitus screw-and glue types of lugged carbon frames where discontinued. More recently (in this century), a friend just replaced his Boardman CF bike and given our being in the US, it was not covered for warranty replacement. So I talked him into Ti and he'll never need a new frame again.

I do

A member of My Bicycle Club died after a failure of his new carbon frame on a new bicycle. The top tube failed while riding. He fell over the handlebars and died. He was wearing a helmet also.

Materials fail at a much lower rate than we make mistakes in bike maintenance, handling, etc. It would more useful to get a list of most common human errors that cause bike accidents rather than failing materials stories. For example pinching a tube when installing a clincher then having a blowout, etc

From an old friend and framebuilder. More here, not just carbon:

Broken Bikes & Parts

We worked at the same shop, I was in repair and retail, he was the head custom guy in the (steel and Ti) frameshop. We had several customers with early Kestrels who (it seemed, anyway) were sending them back once a year to repair a crack here or a split there. It didn't seem like it was ever the same place twice. No doubt, if they'd kept riding they'd probably have failed in some spectacular way.

1990's Giant Cadex with a 180-200lb rider catching air.

I think those were bonded to aluminum lugs if I remember correctly. I can't imagine something like that happening on even the cheapest open mold modern carbon frame.
I used to do stuff like that all the time on my Cadex, destroyed the rockshock mag 20 but the frame lives on with zero assplosions in the last 28 years. Granted Im also 28 years older now and don't tend to beat on stuff like I used to.

base2, my husband's Trek Domane also has a hole in it. His water bottle holder lost a screw which wedged itself into the frame next to the chainrings. He unscrewed it to get it out. I convinced him the next day to use his Gunner instead on a hill ride. We'll see if Trek will replace the frame.

Yikes! I suppose a great deal depends on how events unfolded. If it looks pretty mangled then having a Trek shop do their thing certainly wouldn't hurt. If nothing else just for reassurance.

Whether they warrenty the frame for dropping a bolt is anyone's guess, but I think you could make the case that a wedged bolt & a wedged chain really are different in that a bolt puts all the force in a single point, unlike a chain that would wedge with the same force over a large area.

"Freak thing happened while riding with this shop installed bolt." might have a different outcome than "I dropped it."

Good luck, I hope they can determine a suitable outcome for you.
