Issue
In the brake actuator control computer of these hybrid vehicles, insufficient consideration during development of the control program may prevent brake hydraulic pressure from being adjusted correctly during cornering braking events. As a result, the intended braking force may not be achieved momentarily, and stopping distance may be longer than expected.
Corrective action
Reprogram the brake actuator control computer on all vehicles with the corrected software.

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。
