When I got the car home I started cleaning and seen mold under the weather mats. 1 month after purchase the sun roof and sun shade stopped working. The smell got worse and I noticed every time it rains the floor is soaking wet. Massive amounts of water is draining into the car from the rear seats causing black mold. After doing research this is a known issue with this vehicle. Terrible.”
