Consumer Description

Hi- I have a Toyota Prius 2010 model and I encountered a braking failure yesterday. My ABS lights, brake lights and another light came up on my dashboard of the car. Upon diagnosis, I was informed by Toyota dealership that my car has a faulty C1391 - Abnormal leak in accumulator. This condition may be caused by small internal brake fluid leak inside the brake booster assembly with master cylinder. This is a known issue by Toyota and lots of press coverage on this issue since the past few years. I was told today that if this issue occurred within 10 year or purchase or <150K then the repair work would be covered by Toyota. I purchased the car in 2010 and I past the 10 year mark but mileage coverage is 125K (<150K). Toyota is unwilling to bear the cost and would want me to pay for the fix. This is a known issue with Toyota and the braking system can fail anytime before/or after 10 year mark. It is now costing me $3000 to repair. I am shocked with the Toyota's response in this matter. There are lots of blogs I read online who have similar issue.
