Infrequent puddles of anti freeze found underneath car.
Huh? Not good. Question? Info about the car?
Maybe take the car to a mechanic?
It goes without saying this is not a condition you need to ignore.
Put a fresh piece of cardboard down where you park your Sonic and the next morning check exactly where the leaking is located. Then look carefully in that area using a flashlight for signs of a cooling system leak. Wet or damp surfaces, corrosion, hard water deposits, etc. Common places for coolant leaks are the radiator and water-pump. Don’t drive the car unless the coolant level in the radiator is ok.
