2004 Toyota Sienna Mini van - windshield cracks immediately even if it receives an extremely small (less than half a milimeter) stone chip on the edges of the windshield. As soon as there is an extremely small stone / pebble chip, it will crack right away.
: the contact stated that the vehicle presented a stress crack to the windshield while parked. The vehicle was taken to the dealers who determined that vehicle should be taken to the insurance company and that the crack to the windshield was not part of a defect. The manufacturer was also contacted and refused inspection of the vehicle. The windshield had not been replaced.
While driving to florida noted that there were stains on both windshields either from a manufacturers defect or from the windshield washer solvent which appeared to be of gel consistency. When checked by the dealership I was told it was hard water stains but they were unable to remove the stains. When inspected by the manufacturers rep at the dealership he refused any aid. These stains present a safety hazard when driving at night and in bad weather. Nothing is being done to correct this problem. This is the third stage of the dispute process for me and Toyota is not acknowledging any responsibility for the problem that exists. This make very unsafe driving conditions especially on interstates like 95 when we head south for the winter.
