I currently own a Highlander and I bought it brand new from the dealership back in , so i've been the only owner and i've always taken good care of it.

The source of the leak turned out to be missing rubber grommet hole plugs under the rear bumper. Water was flowing into the holes and collecting inside the frame of the car, eventually making its way into the cabin. The same principle can also be applied when troubleshooting water leaks on other models of Toyota or Lexus cars, as they often share similar parts and frame design. A water leak can cause corrosion or some serious damage to the electric system, and in my case to the hybrid battery located on the floor under the rear passenger seat. It can also cause mold and bad smell if the water stays on the carpet for too long. The problem was well hidden from plain sight. I tried many of their suggestions, like cleaning sunroof or AC condenser draining tubes, checking doors and roof racks insulation, door trim and windows weather moldings, etc. Months went by, and I kept dealing with wet carpets and kept checking online forums for the latest updates on this problem. At that point, I was willing to try anything in Florida it rains every single day in summer…. Removing the rear bumper cover was quite easy. There will be two screws under the rear door, three more in the wheel wells on each side, and two screws holding each mudflap. In addition, there will be 5 more screws and 5 push-pin fasteners on the bottom of the bumper cover. Those screws and fasteners come in all sorts of shapes and sizes, so you may want to keep them organized or take notes where everything goes.

If you are trying to figure out if your Toyota Highlander is leaking water , the first thing we need to do is determine if you have coolant or water underneath of the vehicle. Coolant is sweet smelling and is typically orange, green, or pink. It might not seem possible to determine the color of the liquid in question, but a paper towel allowed to soak up enough coolant definitely will begin to show pigment. Water is tasteless and odorless.
