I have washed my Solstice two times now and both times I noticed when I removed the drivers side carpered floor mat, it was wet along the left edge. I also felt the carpet along the edge of the floorboard which was also wet. I looked for signs of water running from the top down to the floor boards and couldn't find anything. I'm guessing it had to be 2 or 3 ounces of water to make it as wet as it was. I'm using a hose and just letting the water flow over the car and not using any high pressure. Next time I need to wash it, I'll get the wife to hose it down and I'll sit inside and watch what happens. I don't want to take it back to the dealer at this point because I doubt they have any experience with this car since it was their first one and I don't want them learning and experimenting with mine. Has any other owner seen this? You might not notice unless you pulled out the floor mat and checked.
