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, the electrical power cords of some dealer installed block heaters may have been improperly manufactured, causing the wires to contact each other, resulting in a short circuit. A short circuit could lead to a fire which would increase the risk of injury and/or damage to property. Correction: For vehicles where the subject block heater was approved for installation, the dealer will replace the block heater assembly with a new one of an improved design. For vehicles where the subject block heater was not approved for installation, dealers will remove the block heater assembly. In the interim, until the remedy can be performed, dealers will cut the plug end from the block heater cord to disable the block heater's operation.
