TIL getting an elevator tech to just come out to look at your building's elevator is about $1600. If it's an easy fix, that's all you need to pay. If it's not, it goes up significantly....
I'm not going to claim that elevator malpractice isn't possible, but no elevator is designed with a single point of failure for any safety critical system, so I don't think it's easy or likely to make a mistake that would cause a safety issue.
