Overview
| MLIT filing number | 1153750 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | September 19, 2023 |
| Manufacturer(s) | Isuzu |
| Component | Cooling system |
| Production period | June 29, 2018 — December 28, 2022 |
| Vehicles affected | 1,950 units |
Defect
On refrigerated/frozen transport vehicles equipped with a thermal management (heating) unit, insufficient design verification resulted in inadequate clearance between the refrigeration unit piping and the rear face of the cab. As the vehicle ages, settling of the cab suspension and related components causes repeated contact between the refrigeration unit piping and the cab rear surface, leading to coolant leak. If operation continues in this condition, the vehicle's coolant level warning message and buzzer will activate.
Corrective action
Inspect the refrigeration unit piping on all vehicles and replace the bracket with a redesigned part. If a coolant leak is present, also replace the refrigeration unit piping.

状況
冷蔵冷凍車の保温（加温）装置において、設計時の確認が不十分だったため、冷凍機配管とキャビン裏面の隙間が不足している。そのため車両の経年変化によるキャブサスペンション等のへたりにより、冷凍機配管とキャビン裏面が繰り返し干渉し、冷却水が漏れ、 そのままの状態で使用を続けると、車両側の冷却水量低下の警告メッセージ表示及びブザーが吹鳴する。
改善措置
全車両の冷凍機配管を点検し、形状を見直したブラケットに交換する。なお、冷却水が漏れている場合には、冷凍機配管も併せて交換を行う。
