Overview
| MLIT filing number | 1129473 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | May 31, 2012 |
| Manufacturer(s) | Isuzu |
| Component | Engine Assembly |
| Production period | July 22, 2005 — September 25, 2011 |
| Vehicles affected | 23,693 units |
Defect
In the engines used in heavy-duty trucks, the fuel injection control software does not properly manage injection when coolant temperature is high, causing piston temperatures to rise and subjecting the pistons to excessive thermal load. Repeated operation under high coolant temperature conditions may cause cracks to form in the pistons and progress to perforation, resulting in reduced engine output and white smoke from the exhaust. In the worst case, the vehicle may become inoperable.
Corrective action
On all vehicles, reprogram the engine control software. Additionally, inspect the engine; if abnormal noise or white smoke is observed, replace the engine.

状況
大型トラック用エンジンにおいて、冷却水温度が高温の時の燃料噴射制御プログラムが不適切なため、ピストンの温度が高くなり、ピストンに過大な負荷がかかることがある。そのため、高水温状態で繰返し使用すると、ピストンに亀裂が生じ、穴が開き、エンジン出力の低下及び白煙を排出し、最悪の場合、走行不能に至るおそれがある。
改善措置
全車両、エンジン制御プログラムを書き換える。また、エンジンを点検し、異音または白煙排出が見られるものは、エンジンを交換する。
