|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 10, 2014 |
| Manufacturer(s) | Isuzu |
| Component | Computer (Powertrain) |
| Production period | June 16, 2009 — January 22, 2014 |
| Vehicles affected | 500 units |
Defect
On route buses equipped with an automatic transmission, the transmission control unit has insufficient thermal durability. This causes cracks to develop in the solder securing internal components within the unit. Continued operation allows the cracks to propagate, leading to an open-circuit condition and transmission shift faults. In the worst case, the tires may lock at low speed or the engine may become impossible to restart.
Corrective action
On all vehicles, the transmission control unit will be replaced with the corrected/revised part.

状況
自動変速機を搭載した路線バスにおいて、自動変速機を制御するユニットの温度に対する耐久性が不足しているため、ユニット内部の素子を固定しているハンダに亀裂が生じるものがある。そのため、そのままの状態で使用を続けると亀裂が進行し、絶縁状態となり、変速不良をおこし、最悪の場合、低速時においてタイヤがロックしたり、エンジンが再始動不能となるおそれがある。
改善措置
全車両、トランスミッション制御ユニットを対策品に交換する。
