|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | February 1, 2018 |

| Component | Pressure Control/Transmission Unit |
| Production period | August 2015 — December 11, 2017 |
| Vehicles affected | 14,615 units |
Defect
The master cylinder was designed without accounting for manufacturing variation in the booster's internal spring. This allows the piston to be pushed at an angle, increasing sliding resistance against the cup seal. When the brake pedal is depressed rapidly, the cup seal may roll over and fold. Brake fluid then leaks from the seal into the interior of the booster. Continued use causes the warning light to illuminate and, in the worst case, braking force decreases and stopping distance is extended.
Corrective action
On all vehicles, apply a dedicated lubricant to the master cylinder piston.

状況
ブレーキマスターシリンダにおいて、倍力装置内部のスプリングの製造のバラツキを考慮した設計をしていなかったため、ピストンが傾いて押されカップシールとの摺動抵抗が高くなり、ブレーキペダルを速く踏みこんだ際にカップシールが捲れることがある。そのため、シール部から倍力装置内部にブレーキ液が漏れ、そのままの状態で使用を続けると警告灯が点灯し、最悪の場合、制動力が低下して制動距離が長くなるおそれがある。
改善措置
全車両、当該マスターシリンダのピストンに専用の潤滑剤を塗布する。
