The brake actuator/master cylinder has been diagnosed as malfunctioning and failing to maintain hydraulic pressure. The brake booster pump initially began cycling approximately every 10 seconds while the vehicle was in READY mode, stationary, and without the brake pedal being applied. The cycling subsequently increased to approximately every 3 seconds. The affected components remain installed and are available for inspection upon request prior to repair. Because this condition involves the braking system, I am concerned about the potential for reduced brake assistance or further brake system failure, as well as excessive wear on the booster pump from repeatedly restoring lost pressure. I have limited use of the vehicle while arranging repair. An independent repair facility reproduced and diagnosed the problem. Diagnostic testing produced DTC C1391 (Accumulator Leak Malfunction), and the brake actuator/master cylinder was diagnosed as the source of the pressure loss and recommended for replacement. The vehicle has not been inspected for this condition by the manufacturer, police, or insurance representatives. The primary symptom was increasingly frequent brake booster pump operation without brake application. Toyota previously established a Customer Support Program addressing certain brake booster/brake booster pump assembly failures in 2011–2015 Prius vehicles, including conditions associated with C1391. The vehicle is below 150,000 miles but outside the program's time limitation.","products":[{"type":"Vehicle","productYear":"2011","productMake":"TOYOTA","productModel":"PRIUS","manufacturer":"Toyota Motor Corporation"}]}]}
