Filing in context
The Other (electrical equipment) is the most frequently cited component category in this archive, appearing in 23 of its 4,890 filings. This filing is one of 24 Isuzu notifications from 2025 in this archive. For scale, 2,635 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 7 months.
Defect
In the high-voltage circuit, the sub-junction box is improperly designed, causing connector terminals to overheat abnormally and sustain melt damage. This reduces insulation resistance, illuminating the EV system warning lamp and activating the fail-safe function, which cuts drive motor output and may render the vehicle inoperable. Additionally, connector damage may cause the harness to separate, cutting power to the hybrid inverter and drive motor. In the worst case, the vehicle may become inoperable.
Corrective action
On all vehicles, replace the sub-junction box with the corrected part. If specific fault codes are confirmed, also replace the harness, hybrid inverter, and drive motor with new parts.

状況
高電圧装置回路において、高電圧中継器（サブジャンクションボックス）の設計が不適切なため、コネクタの端子が異常発熱し、端子部が溶損することがある。そのため、絶縁抵抗が低下してＥＶシステム警告灯が点灯するとともに、フェールセーフ機能が作動して駆動用モータの出力を停止し、走行不能に至るおそれがある。また、コネクタ部が破損してハーネスが外れインバータ及び駆動用モータへの電力供給が遮断され、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、サブジャンクションボックスを対策品に交換する。また、特定の故障コードが確認された場合は、ハーネスおよびインバータと駆動用モータを新品に交換する。
