On 12/15/16 I was driving my 2011 Nissan Murano awd and when braking for a left turn lane on a local street (going about 30 mph) the brake pedal all of a sudden had no pressure & went all the way to the floor. I could not stop the car & I had to veer to the right to avoid hitting a car in front of me. Towed the car to the Nissan dealer the next day, 12/16/16, & they said it was the master brake cylinder. They replaced the master brake cylinder for about $700 & it was working normally except for a slight whirring sound. On 2/6/17, approximately a month and a half later. I was entering a freeway on ramp (curving type of on ramp approximately 45 mph) and the brakes went to the floor again with no pressure. I had to sharply turn to the right to avoid hitting the car in front and coast to a stop. Took the car to the same dealer and they said the problem was now worn front brakes $400. Then they called a little later and changed their diagnosis and said the issue was now the abs actuator, $1900. Did some research online and found that Nissan has a recall for certain year Murano abs actuators. I believe they should expand the recall because it seems to be affecting my 2011 Murano and I have read many 2009 Murano owners experiencing many of the same issues I am. Interestingly both times the brakes failed were on very rainy days. I think this issue should be addressed before a bad accident occurs where there could be a fatality.
