    I have a 2013 Prius 2 that I purchased used last year.

    Recently its been raining and I've noticed water pooling on the drivers side floor mat, as you can see below I removed some of the paneling and can't see anything amiss. There is a small but consistent drip.

    I originally thought it must be an AC drain but looks like its on the passenger side on this car. There is a very small amount of water on the passenger side but it is very noticeable on the drivers side.

    Any common issues I should be looking into? Really hard to search since everything comes up as AC drain.

    My guess is, you have a windshield leak. Not knowing the history of the car, it may have been replaced. Look at the lower driver side windshield just above the VIN plate and see if it's a genuine Toyota glass. There will be a laser etched label there. If it is determined that it's an aftermarket glass that may be a clue.

    yup checked it and it has already been replaced. good thinking!

    it happens even in very light rain so I'll try to hose it this weekend to confirm before replacing it.

    One of the most common problems associated with windshield leak after replacement of glass is the compromise of the wet sealant due to shutting the doors with the windows rolled up. With the cabin sealed up, the closing of the door/doors causes interior pressurization. This, in turn, forces the wet sealant out of place causing voids. Rookie mistake.
