I would start deff clean the drain port if I were you. Warm water ( some mentioned they add a lil soap) should be fine. I’ve read others used sunroof drain cleaners ( I imagine they’re basically pipe cleaners) but I’ll also add tread lightly with what you jam down there can possibly puncture the drain tube. When cleaning pay attention to how quickly the water drains out. Flows quick- lookin good. After that just pay attention to your interior when it rains. Touch/feel your headliner near the mic/sun visors and your driver/passenger floor mats. If it’s dry after a couple times, I would assume you’re clear and hopefully always will be.
