I'm having this problem now and it is raining here every day lately. It seemed to me to be the screw mentioned previously and we made that assessment before I looked it up on the forum. Fortunatley the floor mats I have currently, will collect and hold the water since it is not a profuse amount. The same thing happened with my Isuzu Rodeo. What's the deal? Why do they think everyone has access to a garage? LOL
