Hazard
In hybrid vehicles, improper machining of high-pressure fuel pump components can allow metal particles to become trapped between pump components and machining fixtures during processing. This can cause cracks to develop at the machined edge, which may propagate through the pump under operating vibrations, potentially resulting in fuel leakage.

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。
Remedy
All vehicles: measure HC concentration near the high-pressure fuel pump and replace units exceeding the standard threshold with corrective parts.
