I have a 2017 platinum murano. I bought it brand new from the dealership. It has never been wrecked. Every time there is a heavy rain, my trunk and floors (front and back) are drenched! There aren't any water stains on or around the moon roof. Is it coming in through the seals around the doors and trunk? I have to have the carpets shampooed now because there is mold under the car mats! Any advice?
