Yes there are. For one thing, antifreeze will leak in places where plain water wont. The higher the concentration of antifreez, the more likely you could have a leak somwhere.

BTW, I don't know of any dealer or independant garage that actally uses distilled water when replacing antifreez so, the earth will still be in it's orbit if you use clean, plain tap water.
