Recalls for the 2006 Toyota Sienna: 11
In the affected vehicles, due to a problem within the shift lock assembly, the shift lever may be moved out of the 'Park' position without depressing the brake pedal. If the shift lever can be moved from the "Park" position without depressing the brake pedal and the parking brake is not applied, the vehicle may roll, increasing the risk of a crash.
The electrical wiring in the seat heaters may be damaged when the seat cushion is compressed. If damaged, the copper strand heating element may short circuit, increasing the risk of a fire.
The affected vehicles may experience compression of the seat cushion which may damage the seat heater wiring. Damage to the seat heater wiring could cause the wires to short, increasing the risk of the seat burning and causing personal injury to the occupant.
The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier. If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.
The six way power seat base may have a defective (Cold) weld on the pivot pin which is welded to the swivel plate. The weld could fail. The seat occupant may be injured if the seat base pin were to break.
The subject vehicles are equipped with the spare tire stowed under the vehicle. The cable may break due to excessive corrosion and the spare tire may separate from the vehicle, possibly resulting in a vehicle crash.
These vehicles were sold without the requisite load carrying capacity modification labels. A driver may overload a vehicle which may increase the risk of a crash.
These vehicles were sold between september 1, 2005 and june 2, 2008 without the requisite load carrying capacity modification labels. This does not meet the standard requirements.
The vehicle capacity weight on the tire and loading information label and the gvwr on the certification label is insufficient for certain vehicles. Some vehicles were accessorized through vehicle processing centers and had accessories installed that caused the vehicle to exceed the gvwr value. The gvwr is insufficient for the load carrying capacity of the vehicles.
These vehicles were not equipped with load carrying capacity modification labels which fails to conform with the requirements of federal motor vehicle safety standard no. 110, "Tire selection and rims." Incorrect load carrying capacity modification labels could result in the vehicle being overloaded, increasing the risk of a crash.

The gas struts used to help lift and support the rear power liftgate could wear out sooner than expected. If not repaired, the gas struts may not be able to support the weight of the liftgate when it is open eventually, the gas struts could deteriorate to the point that the liftgate will fall about ten inches after it reaches the fully open…
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
