What should I do if the car parked in the community keeps calling no one to drive away?

You can let the property or the management Committee contact the owner first. If the property service center has access to vehicle registration information, you can query the contact information of the owner. If you can't contact, you can call the police and contact the owner through vehicle registration information inquiry. If you still can't get in touch, see if the public security organ can drag it away according to zombie car.
