What the notice says 可変容量オイルポンプにおいて、可変部のステータ（固定子）に採用した材質の耐久性検証が不十分であったため、運転状況に応じて油圧制御を繰り返すことで、ハウジングカバーのステータ摺動面が損傷・摩耗することがある。そのため、そのままの状態で使用を続けると、適正な油圧が確保できず、インストルメントクラスタに「エンジン油圧低下」の警告メッセージの表示及び警告灯の点灯とともにエンジン出力が制限され、さらにそのままの状態で走行すると、エンジンが焼き付き、走行不能に至るおそれがある。

Is your vehicle included? Check with your VIN at MLIT, or ask a dealer. This page is an independent copy of the notice, kept so you can see what changed after it was published. It is not the authority, and the authority’s own text is the one to act on.

Register
Japan — Ministry of Land, Infrastructure, Transport and Tourism

What the ministry says is wrong

可変容量オイルポンプにおいて、可変部のステータ（固定子）に採用した材質の耐久性検証が不十分であったため、運転状況に応じて油圧制御を繰り返すことで、ハウジングカバーのステータ摺動面が損傷・摩耗することがある。そのため、そのままの状態で使用を続けると、適正な油圧が確保できず、インストルメントクラスタに「エンジン油圧低下」の警告メッセージの表示及び警告灯の点灯とともにエンジン出力が制限され、さらにそのままの状態で走行すると、エンジンが焼き付き、走行不能に至るおそれがある。

What is to be done about it

全車両、オイルポンプを対策品へ交換するとともに、オイルコントロールバルブへの油路を変更する。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Source: Ministry of Land, Infrastructure, Transport and Tourism website （出典：国土交通省ウェブサイト）, used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

ＵＤトラックス elsewhere in this register

ＵＤトラックス is named on 230 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 潤滑装置

66 notices in this register name 潤滑装置. A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a UD Trucks: 231 in the register, and 201 Japanese vehicle recall notifications filed in 2026.
