A stripped lug nut or bolt
A stripped drain plug
etc, etc.
Let me say that this only applies if you are the only one who has ever worked on the failed component. In my case I don't let anybody else touch my truck, no one but me has opened the hood of my truck since I drove it off the dealer's lot ten years ago. So if a drain plug strips or a lug nut gets damaged, I have only myself to blame.
Even when buy I tires from Costco, I take the wheels off myself and drop them off at Costco for new tires to be mounted on the rims. The extra work involved is worth it to me to ensure that the lugs are torqued properly and that the plastic centre caps do not crack from the tech using an impact gun on it.
One only has control over one's own actions, so if a quick lube damages the engine oil drain plug from cross threading or over tightening, that is beyond your control. But there is no excuse for you inflicting the damage.
