The cabin air pressure vents behind the back seat are leaking letting water into the vehicle. The seals have dried up. It's causing a moldy smell in the vehicle.

Toyota addressed this issue with the frame paint peeling off long ago but they have not launched a customer support program to solve the problem yet. When we reached their Brand Engagement center line (1-888-270-9371) and they do not provide a hard or estimated date to launch the repair program. The vehicle was already inspected by Round Rock Tx Toyota service (PDF page) certifying the issue is a manufacturer responsibility. Please take care of this situation promptly.

The cabin vent system appears to have a design defect, specifically the passenger-side vent located in the back of the cabin. This component is available for inspection upon request. The dealership, Santa Cruz Toyota, has declined to replace the part despite acknowledging the issue. The concern lies in the vent's design, as it allows water to enter the cabin instead of just expelling air. The water intrusion caused by this malfunction poses a safety risk in two ways. First, the presence of water on the floor increases the chance of an electrical fire due to the numerous electrical wires running underneath. Second, mildew spores can grow on the wet undercarpet padding, creating a health hazard. This problem has been confirmed by Santa Cruz Toyota, and we have video evidence to support the claim. While Santa Cruz Toyota has inspected the vehicle, our request for a direct inspection from the manufacturer, Toyota, has not been successful. There weren't any warning lights or messages prior to the failure. However, the issue became apparent after the heavy rains of 2023 in California, when we discovered water accumulated under the passenger-side carpet padding.
