The electric car was lost in the community. Are they responsible for the property? If the property management does not compensate, how to sue the property management?

Have a certain responsibility. You can report the case, and the public security will handle it as a criminal case; However, whether the lost property of electric vehicles should be compensated depends on the actual contract scope. If the residential property collects management fees, it shall guarantee the owners' obligation not to lose electric vehicles. This is equivalent to a consignment contract. If the custodian loses the property entrusted by others, it shall be liable for compensation according to law.
