I registered just to thank the OP and everyone here for their advice. I have a 2015 with only 22K miles and my wife came home today and "oh by the way, I think I hear water in the dash board". What?! She said that you could hear sloshing whenever you went around a turn. When you made a left turn, the blower motor would kick on high. So of course I paniced and took it for a test drive. Sure enough, I heard it too. I took a different approach and disconnected the battery and took out the blower motor itself. Not much water came out. Hmmm. So I went and got a couple towels to put on the passenger floor, hopped in the car and did about 4 fast laps around our round-about. Nearly a gallon of water poured out (redneck mechanic at its best). I left the motor out so it and the vents could dry out. Came in the house and did a search and found this thread. I got under the car and used my air compressor with the blower attachment and about another 2 liters came out and soaked me. Did the back one too but nothing came out. Thank you again to all for your help.
