general problems of the 2002 Toyota Sienna

The spare tire is mounted under the vehicle with the shrader valve oriented downward for easy access. The wheel is steel and is located so the tires kick up water and road sand and, with this orientation, water is trapped, like in a bowl, and sits on the steel. The paint has long been blasted away from the sand exposure and now the wheel is rusted so badly it is extremely thin and cannot be used without risking failure of the wheel, especially on the front where loads can reach in excess of 2500 pounds in a dynamic fatigue situation. It is important to note this Sienna has been recalled once already for rust in this area, thanks to you guys, as rust was damaging the retaining system and the tire was falling off in traffic. They have seen the rusted wheels and the strength is now unpredictable. Road salt, rain, sand etc. Amounts. The system does not have any type of cover. Dealer told me it was not a problem. We have had 2 flat tires and I think with my wife & kids in the car it is a problem. It is a problem waiting to happen.
