Overview
| MLIT filing number | 1137450 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | January 28, 2016 |
| Manufacturer(s) | Isuzu, Nissan |
| Component | Turbocharger |
| Production period | August 2007 — May 24, 2012 |
| Vehicles affected | 29,871 units |
Defect
On vehicles equipped with a diesel turbo engine, the vacuum hose for the turbocharger has insufficient durability against engine heat, and may develop a crack. Additionally, the DPF (Diesel Particulate Filter) particulate matter (PM) removal control program is improperly designed, and DPF regeneration may be triggered even when excessive PM has accumulated. Continued use may allow abnormal combustion—caused by reduced vacuum pressure from the cracked hose—to further accumulate PM. When the DPF then attempts regeneration, the filter may overheat and sustain damage. In the worst case, the undercover may catch fire.
Corrective action
On all vehicles, the vacuum hose is replaced with a corrected part and the engine control computer is updated to a corrected program. The DPF PM accumulation level is also inspected, and if accumulation is excessive, a forced regeneration is performed.

状況
ディーゼルターボエンジン搭載車において、過給機の負圧ホースの耐久性が不足しているため、エンジンからの被熱により当該ホースに亀裂が発生するおそれがある。また、ＤＰＦ（ディーゼル粒子状物質除去装置）のＰＭ（黒煙等からなる粒子状物質）除去制御プログラムが不適切なため、ＰＭが過度に多量に堆積した場合であってもＤＰＦの再生を行うことがある。そのため、そのまま使用を続けると、当該ホースの亀裂による負圧低下のために発生する異常燃焼によりＰＭが過度に堆積され、そのＤＰＦの再生時にＤＰＦが過度に高温となって破損し、最悪の場合、アンダーカバーが焼損するおそれがある。
改善措置
全車両、当該負圧ホースを対策品と交換するとともに、エンジン制御コンピュータを対策プログラムに修正する。また、ＤＰＦのＰＭ堆積量を点検し、堆積量が多い場合には再生処理を行なう。
