For scale, 4,255 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 1 month.
Defect
The impeller of the low-pressure fuel pump is a resin component manufactured under incorrect molding conditions, resulting in insufficient resin density. This causes the impeller to swell and deform when exposed to fuel. The deformed impeller contacts the pump cover, causing the fuel pump to malfunction. In the worst case, the engine may stall while driving.
Corrective action
On all vehicles, replace the low-pressure fuel pump with a corrected part.

状況
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、インペラがポンプカバーと接触して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。
改善措置
全車両、低圧燃料ポンプを対策品と交換する。
