In owners' own words
While parked in the driveway, keys are not in the ignition, no brake pedal, accelerator pressed, can shift the transmission shift knob with little wiggle in the drive, reverse neutral etc.
The vehicle exhibits unpredictable acceleration. When the acceleration is pressed there is a delay of several seconds before the vehicle responds resulting in an unsafe situation.
The gear shift lever on our 2005 Toyota sienna became loose and wobbly. The vehicle was in park and my wife shifted into reverse.

Recalls for the 2005 Toyota Sienna: 12
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.
In the affected vehicles, due to a problem within the shift lock solenoid, there is a possibility that the shift lever could be moved out of Park position without depressing the brake pedal. If the shift lever is moved out of the Park position without the brake applied, the transmission will either engage a drive gear or Neutral, increasing the risk of a backover or roll away crash.
The amount of adhesive agent applied between the outer ring and the torsional rubber damper (Inner ring) in the crankshaft pulley may be inadequate. In some cases, the belt for the power steering pump may become detached from the pulley which could result in a loss of power steering and a sudden increase in steering effort, increasing the risk of a crash.
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.
Toyota is conducting a safety improvement campaign involving 196,222 my 2004-2006 Toyota sienna vehicles equipped with power rear liftgate struts. 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…
On certain Mini vans, in the middle row seating position, the shoulder portion of the seat belt may bind in the bezel trim piece. If the seat belt binds in the bezel, that extra webbing may exist in the seat belt which could result in an improperly fitted seat belt on a passenger.
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.
