You open your car door and hear a strange splashing sound. “It’s not supposed to make that noise,” you think to yourself. But it is and you’re left confused and wondering how water could have possibly accumulated in such a strange place.

Well, turns out it's not as strange as you’d think. Here’s how it happens and what to do about it to avoid further issues.

In a trending video with more than 159,000 views, content creator and dad John (@batroc_the_leaper) said that his daughter heard something strange inside her car door.

"My daughter claims there is water inside the door of her 2020 Lexus RX 350. Let's check it out," he says as he heads to the car.

He opens the door of the Lexus and rocks it back and forth, and you can clearly hear water sloshing around inside.
