autoexpulsarse

Rare, used of a person or a mechanism ejecting itself from a group, system, or process — for people, usually figurative (behaving badly enough to force one's own removal).

• Con su actitud, prácticamente se autoexpulsó del equipo. — With his attitude, he practically got himself kicked off the team.
• El sistema de seguridad puede autoexpulsar un archivo corrupto. — The security system can automatically eject a corrupted file.
• Nadie lo echó; se autoexpulsó al dejar de asistir a las reuniones. — No one kicked him out; he expelled himself by no longer attending meetings.

Mostly figurative for people — a learner shouldn't expect it in formal legal contexts, where expulsar (passive, done by an authority) is the normal choice.
