A maple with peeling bark and a scar at the base likely had a major root damaged at planting. The dead root caused trunk damage above, which is now visible as bark sloughs off. The tree is attempting to heal (callus formation).
Consult a certified arborist (ISA member) for a health assessment. The Georgia Arborist Association can provide referrals. The tree's stability depends on limb structure and decay extent.
