Noticed slow drip leak of what appears to be water driping behind the rear passenger wheel quarter panel. It is slowly dripping from a bolt. Right above this area in the trunk is a plastic storage compartment that seems intact. I did notice wet carpeting in the trunk on the passenger side a few days ago but could not find a source for the water. I dismissed it as something that spilled in the trunk. Now the trunk is dry and the car is slowly leaking. Any thoughts?
