The freeze plugs were designed to pop out if the cooling system froze, in order to prevent the engine block from getting cracked. The freeze plugs are susceptible to getting damaged from corrosion in the cooling system, and will rust through, and start leaking coolant. This is caused by the cooling system not being serviced, or serviced using regular water instead of distilled water. I recommend having a mechanic, such as one from YourMechanic, inspect your leak to identify and quote the repairs needed.
