Crepe Myrtle is a deciduous tree and early Autumn weather will trigger leaf drop.

If the tree drops it's leaves outside of the Autumn time frame, it could be a fungus issue.

If you suspect fungus and not due to Autumn weather, rake up all leaves and dispose.

Spray the tree with Neem Oil. Use a 70 % solution and add 2 Tablespoons to a gallon of water. Spray the tree throughly.

Air circulation is key to good tree health.
