Overview
| MLIT filing number | 1133333 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 4, 2014 |
| Manufacturer(s) | Mitsubishi |
| Component | Drive Power Supply (Battery) |
| Production period | January 17, 2013 — November 2013 |
| Vehicles affected | 6,517 units |
Defect
In the Cell Monitor Unit (CMU) inside the drive battery, the control program is incorrect, causing power consumption to continue even after the power switch is turned off or charging is complete and the vehicle is stationary. This causes the battery cell voltage to keep dropping. As a result, the vehicle enters a fail-safe state in which external charging is disabled, the EV system warning light illuminates during driving, operation is restricted to EV driving within the remaining drive battery charge without engine recharging, and both driving output and maximum speed are limited. If driving continues until the battery is depleted, the vehicle becomes inoperable. Depending on the degree of cell voltage drop, the vehicle may also fail to start.
Corrective action
On all vehicles, reprogram the CMU control program with the corrected software.

状況
駆動用電池内のセルモニターユニット（ＣＭＵ）において、制御プログラムが不適切なため、パワースイッチオフもしくは充電が終了して車両が停止していても電力消費が継続し、電池セル電圧が低下し続けることがある。そのため、フェイルセーフ状態（外部充電ができなくなり、走行時はＥＶシステム警告灯が点灯し、エンジンによる充電を行わない駆動用電池残量の範囲でのＥＶ走行のみに制限されるとともに走行出力と最高速度が制限）に入り、そのまま走行を続け電池残量が無くなると、走行不能になる。また、電池セル電圧の低下状態によっては、始動できなくなるおそれがある。
改善措置
全車両、ＣＭＵの制御プログラムを対策品に書き替える。
