An official CAA Japan notice concerns Passenger cars (Mitsubishi eK, Nissan Sakura) - Repair. Braking system (brake master cylinder) defect. ■ Defective component: Braking system (brake master cylinder). ■ Structure, equipment or performance deemed noncompliant with standards, and its cause: Due to an inappropriate piston shape in the brake master cylinder, the piston may fail to return to its normal position when the brake auto hold function (*1) or hill start assist function (*2) is released, causing brake drag. If the vehicle continues to be used in this condition, it may decelerate more than intended when the accelerator pedal is released. The driver may also press the accelerator pedal further because the vehicle does not accelerate. In the worst case, if the brake drag clears while driving, unintended acceleration may occur. *1: A function that keeps the vehicle stationary after the driver stops by applying the brake, even when the driver's foot is removed from the pedal. *2: A function that maintains braking for up to 2 seconds while the driver moves their foot from the brake pedal to the accelerator pedal, to prevent the vehicle from rolling backward during a hill start. Published 2025-06-12.
What to do now
Recall notification number: 5663. ■ Corrective measures: Replace the brake master cylinder with an improved part on all vehicles.
