Charge cord on Moto G5 Plus overheated and charge port problem.

Moto G5 plus, phone end of the charge cord overheated, melted cord end and plastic around the charge port. (Using the Motorola turbo charger)

The connector has never seemed to seat properly in the charge port on the phone. It loses connection of the the cord or phone is jostled even slightly. Thinking there may be debris in the port I have attempted clean it out gently and with compressed air. That may have helped some, but only marginally if so.

Now the overheating.

I have connected a new cord, still a tenuous connection, and the phone is charging on turbo.

Any suggestions re: this problem are welcome.

Can the charge port be replaced and how difficult might that be? I have done screen, batter, etc. on several iPhone models. (using the very helpful guides here at iFixit)
