after a pretty hard rain today, i leave work to find a small puddle of water on the rubber floor mat on the passanger side, right below the glove box . . . i'm still under warranty so i plan to take this to the dealership next week . . . could this be coming from the roof rack? i did find a wet spot in the headliner after a trip to the autowash several weeks ago. this time the headliner appeared to be 100% dry on the surface. any suggestions as to what i should encourage the dealer to fix or look at?
