Defect
The master cylinder piston geometry is incorrect. When the brake auto-hold function (Note 1) or hill-start assist function (Note 2) releases, the piston may not return fully to its home position, causing brake drag. Continued operation with this condition may cause greater-than-intended deceleration when the accelerator pedal is released. The driver may respond by pressing the accelerator more deeply, and in the worst case, if the brake drag suddenly clears while driving, unintended acceleration may occur. Note 1: Auto-hold maintains the vehicle at a standstill after the driver releases the brake pedal following a stop. Note 2: Hill-start assist holds brake pressure for up to two seconds while the driver transitions from the brake pedal to the accelerator during a hill start, preventing rollback.
Corrective action
On all vehicles, replace the master cylinder with a corrected part.

状況
ブレーキマスターシリンダーにおいてピストン形状が不適切なため、ブレーキオートホールド機能（※１）、およびヒルスタートアシスト機能（※２）解除時に、ピストンが正規位置まで戻らず、ブレーキを引きずることがある。そのため、そのままの状態で使用を続けると、アクセルペダルを離した際に、意図した以上に減速することがある。また、加速しないことでアクセルペダルを踏みこむ時があり、最悪の場合、走行中にブレーキの引きずりが解消すると、意図しない加速をするおそれがある。 ※１：ブレーキを踏んで停車したときにペダルから足を離しても停車状態を維持する機能。 ※２：坂道発進での車の後退を防ぐため、ブレーキペダルからアクセルペダルに踏み替える間、ブレーキを最大２秒間キープする機能。
改善措置
全車両、ブレーキマスターシリンダーを対策品と交換する。
