Overview
| MLIT filing number | 1136292 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | September 3, 2015 |
| Manufacturer(s) | Mitsubishi, Nissan |
| Component | Fuel pump |
| Production period | April 25, 2013 — June 19, 2015 |
| Vehicles affected | 451,369 units |
Defect
During manufacturing, inadequate fuel flow control results in some fuel pumps delivering insufficient fuel flow. Separately, an inadequate control program in the engine control unit (engine ECU) may cause excessive fuel injection quantity. Compounded by an incorrect spark plug specification that promotes plug fouling, these conditions may cause extended cranking time or inability to start the engine.
Corrective action
On all vehicles, reprogram the engine ECU with the corrected/updated software. Depending on vehicle classification, if improvement of the fuel pump or spark plugs is required, inspect both components; replace the fuel pump with a conforming unit and replace the spark plugs with the revised-specification parts.

状況
燃料ポンプにおいて、製造時の燃料流量の管理が不適切なため、燃料流量が少ないものがある。また、エンジンを制御するコントロールユニット（エンジンＥＣＵ）の制御プログラムが不適切なため、燃料噴射量が過剰となることがある。これらに加えて、点火プラグの仕様が不適切なため、点火プラグのくすぶりが発生し、始動時間が長くなったり、始動不能に至ったりするおそれがある。
改善措置
全車両、エンジンＥＣＵのプログラムを対策品に書き替える。また、車両の類別により燃料ポンプおよび点火プラグの改善が必要な場合は、燃料ポンプおよび点火プラグを確認し、燃料ポンプは良品に交換、点火プラグは仕様変更品に交換する。
