2016 Toyota Tacoma

On certain vehicles, the seal between the rear differential and the axle housing could degrade due to contact variation. This could result in leaking differential oil. If the vehicle is operated in this condition, damage to the differential could occur, and could potentially result in noise, reduced motive power and rear axle lockup. These issues could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the rear differential for leaks. If no leaks are found, fastening nuts will be re-tightened. If leaks are found, the differential gasket will be replaced, and new differential fastening nuts installed. Note: This applies to vehicles equipped with automatic transmission and non-locking differentials only.

On certain vehicles equipped with a V6 engine, the crankshaft rotor may have been produced with an anti-corrosion coating that is too thick. This could cause interference with the crank position sensor, potentially causing the vehicle to stall, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the crank position sensor with one of an improved design.

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.

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: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 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.
