Affected vehicles

Toyota Kluger Hybrid 2005–2006 Toyota Harrier Hybrid 2005–2006

Hazard

In the hybrid system, the power converter (DC-AC inverter) control board may have insufficient soldering, causing component damage on the board due to heat generation from high current during high-load driving. In the worst case, high-voltage system current may flow into the control circuit, causing the power circuit fuse to blow and resulting in sudden hybrid system shutdown during driving, rendering the vehicle unable to operate.

ハイブリッドシステムにおいて、電力変換器(DC-ACインバータ)制御基板の半田付けに不十分なものがあるため、高負荷走行時の大電流による発熱により基板上の素子が損傷することがある。最悪の場合、高電圧系統の電流が制御系回路に流れ、電源回路のヒューズが切れることで、走行中にハイブリッドシステムが突然停止して、走行不能となるおそれがある。

Remedy

Check the manufacturing number of the power converter on all vehicles and replace those identified with modules containing properly assembled boards.
