An official CAA Japan notice concerns Passenger cars (Volkswagen Passat 1.5 TSI and 4 other models) - Repair. Defect in the braking system (electric brake booster). Defective part (component name): Braking system (electric brake booster). Condition and cause of the structure, equipment or performance deemed noncompliant with standards: Due to insufficient evaluation of the control program in the electric brake booster control unit, when the system detects for a certain period that the driver has taken their hands off the steering wheel while Travel Assist (*1) is operating, it may incorrectly recognize a brief braking operation performed by the system as a braking operation performed by the driver, causing Travel Assist to be disabled. Consequently, if the driver becomes unable to drive, the system does not switch from Travel Assist to Emergency Assist (*2) and does not sound an audible warning to the driver, failing to comply with safety standards. (*1) Travel Assist: A driving assistance system that supports accelerator, brake and steering operations. (*2) Emergency Assist: An emergency stopping assistance system that automatically brings the vehicle to a safe stop if the driver becomes unable to drive. Published 2025-10-30.
What to do now
