2009 Toyota Matrix

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.

On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Depending on the vehicle model, dealers will either replace the passenger frontal airbag inflator, or replace the airbag assembly. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected.

On certain vehicles, inconsistent application of grease during the manufacturing process could cause the driver's side power window master switch to stick or become inoperative due to electrical contact point wear. This could cause debris to accumulate between the contact points, potentially resulting in an electrical short circuit.  If a short circuit occurs, the switch assembly may overheat, produce smoke, melt and/or potentially lead to a fire causing injury and/or property damage. Correction:  Dealers will inspect the driver's power window master switch and apply a specialized grease that inhibits heat build-up, or replace the power window master switch circuit board, as necessary.  Note: This is an expansion of recall 2012-338.

On certain vehicles, electrical circuitry in the steering wheel assembly may become damaged.  As a result, the driver's airbag may not function as intended, causing the instrument panel airbag warning lamp to illuminate.  Failure of the driver's airbag to deploy during a crash (where deployment is warranted) could increase the risk of injury to the seat occupant.  Correction: Dealers will replace the spiral cable assembly.

On certain vehicles, due to improperly applied grease, the driver's side power window master switch could stick or become inoperative. If attempts are made to lubricate the switch, the switch assembly could overheat and melt. A melting switch may produce smoke and potentially lead to a fire causing property damage and/or personal injury. Correction: Dealers will inspect the driver's power window master switch and apply a specialized grease that inhibits heat build-up, or replace the power window master switch circuit board, as necessary.
