Overview
| MLIT filing number | 1153510 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | July 14, 2023 |
| Manufacturer(s) | Nissan |
| Component | Wiring |
| Production period | December 27, 2017 — August 25, 2021 |
| Vehicles affected | 126,800 units |
Defect
Insufficient verification during development resulted in improper routing of the engine compartment wiring harness. When the tip of a bolt used to secure the engine control unit aligns with a slit in the harness protective sleeve, the bolt tip may penetrate the sleeve and contact the wiring inside directly. Continued operation causes the wire insulation to wear through at the contact point, allowing the bolt tip to touch the conductor and create a short circuit. In the worst case, the drive motor may stop while the vehicle is in motion, rendering the vehicle inoperable.
Corrective action
On all vehicles, install a resin cap on the tip of the engine control unit mounting bolt. If the harness insulation is found to be damaged, repair it.

状況
エンジンルームハーネスにおいて、開発時の検証不足によりハーネスの配策に不備があり、エンジン制御用コントロールユニット固定用ボルトの先端がハーネス保護材のスリット部に位置した場合、ハーネス保護材内側に入り込み、直接、電線配線と接触しているものが有る。そのため、このまま使用を続けると、電気配線の被覆が損傷し、ボルトの先端が芯線に接触することで短絡し、最悪の場合、走行中にモーターが停止し走行できなくなるおそれがある。
改善措置
全車両、エンジン制御用コントロールユニット固定用ボルトの先端に樹脂キャップを装着する。なお、当該ハーネス被覆が損傷していた場合は修理する。
