Could be a few things. One thing to check first is that your sunroof drains are clear. If you have one. [Here’s how to do it.](http://bestride.com/research/tips-and-tricks/clear-your-sunroof-drains)

Is it antifreeze? Could be heater core. Does your windshield fog up when you turn defrosters on?

Dear friend,  
Toyota released a redesigned rear hatch seal, also some people were getting water from the rear A/C units clogged condensation drain.

Siennas floor pan is a bit lower in the front so water will pool up front no matter where the leak is. I had water pooling up front from a rear hatch leak.
