Overview
| MLIT filing number | 1155530 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 10, 2024 |
| Manufacturer(s) | Honda |
| Component | Fuel Pump |
| Production period | June 2022 — September 11, 2024 |
| Vehicles affected | 62,844 units |
Defect
On hybrid vehicles, an improper machining process for high-pressure fuel pump components allowed metal particles generated during machining to become trapped between the component and the machining fixture. This causes cracks to form on the machined end face. Continued use allows vibration during pump operation to propagate the cracks through the material, resulting in a fuel leak.
Corrective action
On all vehicles, measure the HC concentration near the high-pressure fuel pump. On any vehicle where the concentration exceeds the specified value, replace the pump with a corrected/revised part.

状況
ハイブリッド車において、高圧燃料ポンプ構成部品の加工工程が不適切なため、加工時の金属粉が当該ポンプの構成部品と加工治具の間に噛み込むものがある。そのため、加工部端面に亀裂が発生し、そのまま使用を続けるとポンプ作動時の振動で亀裂が貫通し、燃料漏れに至るおそれがある。
改善措置
全車両、高圧燃料ポンプ付近のＨＣ濃度を測定し、濃度が基準を超えているものは対策品と交換する。
