I noticed the other day my back floorboard was wet behind the drivers seat. I thought maybe a water bottle may have leaked or something. Well fast forward to today and there was a puddle in the back floorboard. It rained a lot last night. I'm guessing maybe a seal or something isn't doing its job. Everything looks fine from looking at it. My car is parked on a little hill that's why all the water is puddled in the rear. Nothing else is wet besides the floorboard and I haven't drove it in 2 days. I'm gonna take it to the dealer tomorrow.
