Overview
| MLIT filing number | 1127710 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | June 29, 2011 |
| Manufacturer(s) | Toyota |
| Component | Other (Electrical Equipment) |
| Production period | January 31, 2005 — August 2006 |
| Vehicles affected | 11,164 units |
Defect
In the hybrid system, solder joints on the control circuit board of the DC-AC inverter (power converter) are insufficiently bonded. During high-load driving, heat generated by high current flow may damage components on the board. In the worst case, high-voltage current flows into the control circuitry and blows the power circuit fuse, causing the hybrid system to shut down suddenly while driving and rendering the vehicle inoperable.
Corrective action
On all vehicles, verify the serial number of the power converter. On affected units, replace the module with one incorporating a conforming circuit board.

状況
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。
改善措置
全車両、電力変換器の製造番号を確認し、該当するものは基板の良品が組み込まれたモジュールと交換する。
