Some of the 2006-12 RAV4 had
Some of the 2006-12 RAV4 had a defective passenger side windshield cowl cover installed. It was actually missing a water diverter that should have been molded into the underside of the cover. Without this diverter water running down the windshield would go under the cover and straight into the air intake for the cabin. Depending on the slope the car is parked more or less water will pour into the intake. Sometimes the water would just stay in there and eveporate. But if the seals degrade it'll start leaking on to the floor.
