couple of days ago it rained all night where I live and in the morning when I got in my car (2013 ATS) I noticed that the floor is drenched with water. I checked everything was closed properly. Doors windows and sunroof were all closed all the way. I am unable to see where this water had came from but it seems to me from the sunroof. I am guessing sunroof is not draining properly or water are coming out of the drain and into my car. The water is only in the driver side floor. Any one else with an ATS had a similar problem? I would appreciate the input. I am worried that this is not covered under the warranty. I yet to call the dealer, but it is extremely frustrating to spend all this time at the dealer as I had taken this car multiple times already for 5 different recalls. Not sure what to do here.

Thanks GJB. How would I do that? Please forgive my ignorance on car maintenance. I know very little about how to troubleshoot car problems. Where are these vents located? are they near the door? Do I need to remove the door or anything to get to them?

You have a 4 year bumper to bumper warranty....why wouldn't it be covered? Unless you left a window or sunroof open, any improper draining is warranty covered.
OK, I poured water through the driver side vent and I can see the water drain from the bottom. Then I opened the sunroof and poured water through the sunroof drain and I could see the water drip from the bottom. I am not sure now how the water got inside the car over the weekend. I think I will wait until it rain again and see what happens

I tried both sides for the vents and the sunroof. Both seem to be draining just fine. it is really strange as ONLY the area underneath the floor mat is wet. I cannot see any traces of water on the sides leading to the floor. All of the area under the mat is wet.
It is going to be raining again on Friday so I will check if this happens again. I will take it to the dealer at some point. I am just unable to find the time for it now. Maybe next week.

Some people are saying to me that the AC drain pipe might be clogged so AC condensation water not able to get out and therefore coming back inside. I am not sure how to check if that pipe is clogged.
I will try to put paper towels inside the car on multiple places before it rains on Friday and see if I can pin point if any water is leaking from the outside
----------
I suspected it won't be covered because if the cause of it is a clogged drain as a result of dirt or something, then it's not an issue with the car itself. If it is a defect in the car, then yes I know it will be covered. Just need to do as much of testing as I can before i take it to them

The AC draining into the car is a possibility, If the tube pinched during assembly or inserted into the drip tray too far it could overflow.

Finally I was able to pinpoint where the water leak is coming from. (see picture below). It rained last night and in the morning I went to my car and felt the floor and it was drenched with water again. I started looking around and noticed water dripping from the bottom corner of the dashboard right above the foot brake. It seems it is coming from inside the dashboard. I will be calling the dealer and taking it to them next week hopefully.

I'm guessing your wind shield may be leaking and its traveling down into the dash, but just a guess. Let us know what the dealer finds out and this picture should save them time trouble shooting. Take up your floor mat and dry that out fast using wet dry vac and towels. I also suggest a fan until it is dry all the way down to the floor boards so that it does not get musty. Once its very dry you can put the dry floor mat back in.
OK, I got my car back from the dealer yesterday. They said that the sunroof drain was partially clogged and causing water to go back to the dashboard then into my car. They cleaned it and hopefully no more leaking. I will monitor it again when it rains. I did check the sunroof drain before and it seemed working but maybe as they said partially clogged and not able to drain water fast enough.

Also the drain must be pretty long and it may have been blocked low. Did they say how they un blocked it? My roof looks like a tight seal when its closed, I 'm surprised it would let that much water through.
They only said sunroof drain cleaned and they tried again and no leak was happening. I'm also surprised as my roof also seems to be very tight and wondering how much water can it go inside from the rain. When I tested it myself I had poured water directly into the sunroof drain using a water bucket and i was able to see water draining just fine at the bottom of the car. I will have to go with whatever they said and see if this leaking happens again when it rains or the problem is fixed.
