In November 2021, Mazda filed a statutory recall with Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) concerning the Fuel pump, covering the Atenza, Axela and 7 more models. The filing affects 42,505 vehicles manufactured between April 2018 and August 15, 2019.
Overview
| MLIT filing number | 1150430 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 12, 2021 |

Filing in context
The Fuel pump is the most frequently cited component category in this archive, appearing in 37 of its 4,890 filings. This filing is one of 21 Mazda notifications from 2021 in this archive. For scale, 824 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 4 months.
Defect
The impeller (plastic vane wheel) of the low-pressure fuel pump on gasoline-fueled vehicles was molded under incorrect conditions, resulting in insufficient resin density. The low-density impeller absorbs fuel and swells, causing deformation. The deformed impeller contacts the pump case, causing the low-pressure fuel pump to malfunction and, in the worst case, resulting in an engine stall while driving.
Corrective action
On all vehicles, the low-pressure fuel pump is replaced with a corrected part. Because repair parts require time to procure, owners will be notified separately to schedule service once parts are available.

状況
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。
改善措置
全車両、低圧燃料ポンプを対策品に交換する。なお、修理部品の準備に時間を要するため、部品の準備ができ次第、使用者に改めて修理入庫を通知する。
