It isn’t a leak, it is condensate from your air conditioning system and totally normal……….

If coolant on the ground, then you may have a leak from your radiator, a hose or connection. Hit any curbs hard lately? Hope not.

If just water, then most likely just condensation from the a/c system as JFP suggested.

If you have positively determined the leak is coolant (by color or smell of glycol), and it is near the front wheel, you probably have a leaking radiator on that side. Time to put the car up in the air and start removing panels to have a look.........

i've got a leaky water pump.... i have the same symptom as you in that it only leaks after I shut off the car. i believe since once the car is running, it heats up, coolant expands, and it's all under pressure... so when you get home and shut off you are leaking

i'd get it fixed. my car is not being driven now until I get mine to get fixed. I'd HATE to have it finally blow, dump all your coolant, and ovreheat before you coudl get it shut of. given how $$$ it is to repalce an engine, I'd hate to neglect a fix like this only to have it cause it to overheat and cuase damage..... some failures just happen and are unavoidable...this is one you can avoid by fixing it now.

good luck.

You have a water pump that is leaking by the right front wheel? I'd really like to see how that works.....................
