Came out of a restaurant to find a large pool of coolant coming from what appeared to be under the radiator. The pool extended from there to about three feet from the left side of the car. The parking lot sloped that way so completely understandable. Went to auto zone and put water into the empty reservoir. Watched underneath but did not see any leakage. Drove about 15 or so miles home and the low coolant warning did not come back on. Anyone been thru this?
