2011 Toyota Sienna

Issue: 
This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. 

On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. 

Note: This recall only affects the following block heater/cord part numbers:

Safety Risk: 
Engine block heater wiring that overheats or melts could create the risk of a fire. 

Corrective Actions: 
Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.

Issue: 
On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function. 
 
Safety Risk: 
If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury. 
 
Corrective Action: 
Owners will be notified by mail and instructed to take their vehicle to a dealer to have the passenger-front airbag inflator or airbag module replaced.  
Note: The Canadian climate results in the propellant degrading slowly. This recall is being conducted as a precaution to address future risk. It is expected that all airbag inflators will be replaced before their function would be affected.

On certain vehicles equipped with power sliding doors, under certain conditions which impede the opening of the door (such as if the door becomes frozen with ice), the sliding door motor could stall when the door is operated. If the motor stalls, high current in the door motor circuit could be generated, operating the circuit protection for the door motor. If this occurs with the sliding door latch mechanism in an unlatched position, the door could open while driving, increasing the risk of injury to a vehicle occupant. Correction: Dealers will replace the existing junction block and the rear sliding door wire harnesses with newly designed ones. The dealer will also install two sub wire harnesses to connect the junction block to the two rear door wire harnesses.

On certain vehicles operated where road salts are frequently used, corrosion of the spare tire carrier assembly cable may cause the separation of the spare tire stowed under the vehicle.  The spare tire falling on the road surface creates a safety hazard that may result in a crash causing injury and/or property damage. Correction: As an interim measure, dealers will remove the spare tire and store it in the cargo area of the vehicle. Dealers will replace the spare tire carrier assembly when parts become available. Note: This recall supersedes recall 2010-123. Vehicles that were inspected and/or repaired under the previous recall may still be at risk of spare tire separation and will require re-inspection and/or repair.

Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard 110 - Tire Selection and Rims. The combined weight of occupants and cargo, as displayed on the Tire and Loading Information label, does not meet the requirements of the Standard. As such, the vehicle could be unwittingly overloaded, which would result in poor vehicle handling characteristics, increasing the risk of a crash causing property damage and/or personal injury. Correction: Dealers will install an updated Tire and Loading Information label, as well as an owner's manual overlay label.  Customers with certain vehicles equipped with a genuine Toyota trailer hitch and 18” run flat tires or 19” wheels will be presented with an option (1) to remove the trailer hitch or (2) replace the tires (and rims) with new Extra Load Tires.
