What the ministry says is wrong

大型トラック用エンジンにおいて、ターボチャージャのタービンインペラの二次共振時の最大応力部に微小空孔が存在した場合に、微小空孔を起点とした疲労破壊によりタービンインペラが破損して異音、白煙排出、出力不足等が発生し、エンジン警告灯が点灯することがある。そのため、そのままの状態で使用を続けると、ターボチャージャに異常振動が発生し、ターボチャージャ給油パイプが疲労により亀裂してオイルが漏れ、高温部に付着して火災に至るおそれがある。

What is to be done about it

全車両、給油パイプ、給水パイプおよびパイプ固定用ブラケットを対策品に交換する。なお、上記原因によりタービンインペラが破損した場合には、ターボチャージャを無償で交換する。

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

いすゞ elsewhere in this register

いすゞ is named on 823 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 過給機

76 notices in this register name 過給機. 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 an Isuzu: 834 in the register, and 439 Japanese vehicle recall notifications filed in 2021.
