My Sienna 2005 experience intermittent complete brake failure 3 times within 18,000 miles,the brake pedal goes to the floor and it does not slow down, so I coast until I stop. However, when I release the brake pedal and then reapply the brakes, it works fine. A non-Toyota mechanic thinks it's due to malfunction of ABS. The dealership is unable to finds error codes and brakes work fine when the Sienna is in their hands. I scared that the brakes will not work the next time I reapply the brakes.
Has anyone else experience similar problem or have suggestings?
