2007 Toyota Sienna Owner Comments

Sienna 6-cyl

  • 44,900 miles


My complaint involves the Toyota Sienna minivan (mine is a 2007). I believe Toyota is aware of a defect in the rear ac lines which causes them to prematurely corrode near the rear axle. This causes a release of the refrigerant into the atmosphere and mandates the lines be replaced by the owner at a cost of app. $1200. My vehicle was purchased new in May 2007 and has 45K miles- no accidents, always properly maintained. This van was recently recalled for excess corrosion in the spare tire carrier which causes the spare tire to fall out. The following is a quote from their press release: The recall includes certain 1998 through 2010 model year Sienna 2wd vehicles equipped with a spare tire and operated in cold climate areas with high road salt use. In addition to the District of Columbia, vehicles currently registered in the following cold climate states with high road salt usage are covered by this recall: Connecticut, Delaware, Illinois, indianna, Kentucky, Massachusetts, Maryland, Maine, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, Vermont, Wisconsin and West Virginia. The corrosion resistance of the spare tire carrier in insufficient when vehicles are operated in areas where a large amount of road salt is applied. In the worst case, the carrier cable may fail and the spare tire could become separated from the vehicle... the dealership service rep stated to me that he sees this failure very often, and the parts dept. Keeps the parts in stock due to frequency of replacement. The replacement parts have not be improved and carry the same part #. I called Toyota's customer care line and was told they would not provide any assistance. Please search online for others with the same problem- there are many. R134A refrigerant leaking into the atmosphere is a severe environmental problem and Toyota should be held responsible for repairs and costs to consumers.
