Underneath my drivers side rear mat is soaked with water after the rain. What could be causing this? This is the 3rd time now that I have noticed this.

 

Do a search....i have seen this problembefore but can't remember what the fix might have been .

 

sunroof leak, window open, door not closed completely.

put some brown paper (or anything thick that will let you see water spots easily) throughout the interior of the car, and commence spraying with the water hose, checking after each section. this should give you an idea of where the leak is coming from.

 

Yeah i read something about the water running down the A pillars or something. Search.

 

there are rubber drain plugs under the carpet behind the front seat. I bet one of yours is MIA. You should be able to get more from the dealer or from a wrecking yard.
