Why does my CX9 make sloshing sound when turning? on 2011 Mazda CX-9

Yesterday my car sat outdoor in the rain while I was work. Driving home I noticed when I made left turns the vehicle sounded like it was driving through a puddle. The sound came from the front passenger side of the vehicle. As the pavement was wet I attributed the noise to water on the road. However, the noise continued even when there was no noticeable water on the roadway beyond merely wet pavement. The vehicle is still making the noise today. It is only when I turn left as far as I have noticed. Since it rained so much yesterday I thought maybe water was draining from somewhere but now I don't think that is the case since it all should have drained by now. Any ideas? Thanks!

The AC drain is clogged. I have a 2008 CX9 GT it has happened several times ,the dealer fixes for free.

Sorry this is not an answer, but my CX9 started doing the same thing a few weeks ago. When I turn off the a/c it doesn't make the noise. Now 3-4 weeks later the front vents for the a/c or heater don't work but the back vents still do, and it started leaking water in the front passenger floor board. Haven't had a chance to get it in to a mechanic. Would like to know what this could be so I don't over charged when taking it in...Sorry just noticed the answer above. I will try taking it in. Thanks!

The exact thing is happening to my CX9 right now. I went into a cul-de-sack and made turns to the left in circles and water was gushing out of the passenger side floor. I have read mixed reviews. Some people say it's due to the rain. What did you end up having in your car. How did you fix it?
