Issue
In hybrid vehicles, the brake actuator control computer contains a program with insufficient consideration of control logic, which may prevent brake hydraulic pressure from being properly adjusted during braking in a turn. As a result, the intended braking force may be temporarily unavailable, and stopping distance may be longer than expected.
Corrective action
On all vehicles, update the brake actuator control computer program to the corrected specification.

状況
ハイブリッド車のブレーキアクチュエータ用制御コンピュータにおいて、制御プログラムの検討が不十分なため、旋回制動時にブレーキ油圧を適切に調整できないことがある。そのため、一時的に意図どおりの制動力を得られず、予測より制動停止距離が伸びるおそれがある。
改善措置
全車両、ブレーキアクチュエータ用制御コンピュータのプログラムを対策仕様に修正する。
