Was there a massive puddle of pink antifreeze all over the garage floor or tiny droplets of clear water? Did you drive over any deep potholes which may have damaged the radiator or intercooler and its hoses from scraping the road? Because if it isn't just condensed water from the A/C system or a misfortunate driving session (well at least it is still under warranty), I could see a potential recall for all GR Yaris and GR Corollas later this year. Otherwise, I would just keep it as it is and have the exhaust create a smoke screen everytime someone mistakes this car for an Impreza GH hatch
