Hazard

In the low-pressure fuel pump impeller (resin-molded rotor) of gasoline engine vehicles, improper molding conditions result in reduced resin density, causing the impeller to swell and deform when exposed to fuel. This can cause the impeller to contact the pump housing, leading to low-pressure fuel pump malfunction. In the worst case, this may result in engine stall while driving.

ガソリンエンジン車の低圧燃料ポンプのインペラ(樹脂製羽根車)において、成形条件が不適切なため、樹脂密度が低くなって、燃料により膨潤して変形することがある。そのため、インペラがポンプケースと接触して低圧燃料ポンプが作動不良となり、最悪の場合、走行中エンストに至るおそれがある。

Remedy

Replace the low-pressure fuel pump with a corrective-action unit on all vehicles. Due to the time required to prepare replacement parts, owners will be notified of the repair appointment once parts become available.
