Lots. Toasters, refrigerators, robot vacuums, thermostats, smart home lights, etc.
The reason why self-driving cars are extra tricky is both because they have a much more complex task and the negative consequences are sky high. If a robot vacuum screws up, it’s not a big deal. This is why it’s totally irresponsible to advertise something as having “full” autonomy when the stakes are so high.
Are there any truly autonomous machines which don’t require a human to monitor?

Those are mostly automatic, not autonomous.
