| MLIT filing number | 1133332 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 4, 2014 |
| Manufacturer(s) | Mitsubishi |
| Component | Computer (Engine) |
| Production period | January 17, 2013 — March 27, 2013 |
| Vehicles affected | 4,621 units |
Defect
The control programs in the engine control unit (engine ECU) and the PHEV system control unit (PHEV ECU), combined with an incorrect spark plug specification, may cause spark plug fouling when the engine is repeatedly started and stopped for short periods at low temperature. When fouling occurs, the EV system warning light illuminates and operation is restricted to EV driving within the remaining drive battery charge without engine recharging. If driving continues until the battery is depleted, the vehicle becomes inoperable.
Corrective action
On all vehicles, reprogram the engine ECU and PHEV ECU control programs with the corrected software. Additionally, replace the spark plugs with the revised-specification parts.

状況
エンジンを制御するコントロールユニット（エンジンＥＣＵ）とＰＨＥＶシステムを制御するコントロールユニット（ＰＨＥＶ ＥＣＵ）の制御プログラム、および点火プラグの仕様が不適切なため、エンジンが低温の状態で短時間の運転と停止を繰り返した場合、点火プラグのくすぶりが発生することがある。そのため、ＥＶシステム警告灯が点灯し、エンジンによる充電を行わない駆動用電池残量の範囲でのＥＶ走行のみに制限され、そのまま走行を続け電池残量が無くなると、走行不能になる。
改善措置
全車両、エンジンＥＣＵおよびＰＨＥＶ ＥＣＵの制御プログラムを対策品に書き替える。また、点火プラグを仕様変更品に交換する。
