I don't know why that's happened to a low mileage car. Do they sell these "new"? Is it necessary? Does this get worse? Why is this happening?

I have worked in the die casting business for a while and have seen similar patterns where the metal has not cooled enough before the the core and cavity were opened or that area of the mold was not cooled sufficiently enough.
This left the surface molten for a second or so
