I purchased my 2006 Rav-4 new. For the past two years occasionally when it rains, I end up with water in the front passenger floor board. I have taken it the dealership and they could't find anything wrong. They wanted me to pay over 300 to take apart part of the area around the floor board and run smoke in to find the problem. Has any one else had a problem like this? I've started keeping a towel in the floor board just in case it rains but it never happens during a visit to the carwash.
