Recall 1149360 — Ignition coil

Filed April 15, 2021 · Subaru

Overview

MLIT filing number1149360
TypeStatutory Recall (government-mandated recall)
Date filedApril 15, 2021
Manufacturer(s)Subaru
ComponentIgnition coil
Production periodOctober 2016 — March 22, 2019
Vehicles affected137,449 units

Defect

The engine control unit's control program improperly manages the shutdown sequence, causing the ignition coil to remain energized longer than specified. This excess current flow raises the ignition coil's internal temperature, leading to a short circuit and blown fuse. In the worst case, the engine may stall while the vehicle is in motion. Additionally, ignition coils that have already experienced prolonged energization may continue to fail even after the control program is updated, due to accumulated internal damage.

Corrective action

On all vehicles, replace the ignition coil with a new part.

状況

エンジンコントロールユニットの制御プログラムにおいて、エンジンが停止する際の制御が不適切であったため、イグニッションコイルへ必要以上に通電することがある。そのため、イグニッションコイルの内部温度が上昇し回路がショート、ヒューズ切れを起こし、最悪の場合、走行中エンジンが停止するおそれがある。この場合において、既に長通電を経験したイグニッションコイルでは、対策プログラムに書き換えても、内部ダメージの蓄積により不具合に至るおそれがある。

改善措置

全車両、イグニッションコイルを新品に交換する。
