Leaking water passenger side

Hello,

I have a 2011 C300 Mercedes and theirs is a lot of water under the passenger seat to the back floor. I push down on the carpet in the back and more water leaks started to come from back metal pieces. I removed the scuff plates in order to get the water out and was able to.. I live in Miami Florida and it’s been raining everyday so the next day when it rained again the same thing happened.
Any idea what could be the problem.
Thank you

Check that the drains are clear at the base of the windscreen, near the wiper shafts.

YES, sunroof drains are usually the culprit.

Thank you all for your replies, I checked the sunroof drains and they were clogged was able to clean them. Hopefully no more water comes into the car.

If your sunroof drains were indeed clogged and are clear now, I am pretty sure you have solved your issue.
