Radiator problems of the 2005 Toyota Sienna

Under Toyota's customer support program, a technical service bulletin was put out saying that 2005 Toyota Siennas had faulty radiators that cracked in cold weather and could lead to coolant leakage and subsequent engine seizure (safety report #0506). When the weather started getting cold this winter, my radiator cracked and I needed to to be repaired as the engine was running extremely hot. When I found this bulletin and brought it to Toyota's attention they refused to honor it saying that my VIN number was not in the range. When I asked why this was the case, they claimed (they being Toyota's national headquarters) that they had realized the fault and therefore switched the radiators out during production. Upon closer examination, the bulletin was announced by Toyota on January 30, 2006. If what they claim is true, then they were knowingly selling cars with faulty radiators for about a year and a half before they issued the recall. If they were lying, then the recall needs to be extended to include all Toyota Siennas of that year.

During the timing belt and water pump replacement, Toyota technician found radiator had a small leak and suggested to call Toyota company . Toyota representative from company informed the radiators had problems for 2005 Sienna but they will not be able to fix it because mileage is more than 75000 or vehicle is more than 7 years old.

During inspection and repair of other vehicle recalls, it was determined that power steering assembly was severely leaking fluids, that radiator was leaking in 3 places, and air conditioning coils hoses\brackets were corroded and cracked due to manufacturer using two dissimilar metals (such as steel bolts in aluminum assembly) and thereby requiring immediate replacement for safety. Toyota dealership upon inspection declared steering assembly a "critical" repair and issued written documentation. I took vehicle to another shop and they confirmed Toyota's dealers conclusion and also found radiator and conditioning coils problems missed by dealer. All problems have been fixed at owners expense - a recall should be made by manufacturer.

Almost in fire for multiple times! driver is constantly under danger of fire. Toyota customer service responded by offering a $200-300 credit, suggesting Toyota knows there is something wrong for such frequent radiator leaking. But it refuses to disclose details. For the safety of drivers, please investigate. Individual driver like myself is too small to talk to Toyota. Toyota even did not answer my question.
