What the ministry says is wrong

運転支援装置において、衝突被害軽減ブレーキの制御プログラムが不適切なため、カーブ路にあるガイドポストや対向車の進行方向等を正しく認識できず、システムが衝突対象として過敏に反応することがある。そのため、意図しないところで障害物との接近を知らせる警報音が鳴り、衝突被害軽減ブレーキが作動するおそれがある。

What is to be done about it

全車両、運転支援装置の制御プログラムを書き換える。

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

スバル elsewhere in this register

スバル is named on 213 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: 装置その他

210 notices in this register name 装置その他. 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 Subaru: 213 in the register, and 439 Japanese vehicle recall notifications filed in 2021.
