My wife was driving my children on the highway at approximately 55mph and the �brake� icon suddenly flashed red on the dash. My wife attempted to apply the brakes and they did not function or respond other than by making a grinding noise. The pedal was able to go to the floor but with no braking accomplished. To stop the vehicle she had to downshift and let it coast to a stop in a parking lot that was fortunately on her path of travel. There are no leaks in the braking system and the nearby Nissan dealership said it had thrown a c1179 code for a brake booster sensor. Turns out this is a common issue with these models and Nissan lost a class action lawsuit about the issue in California in 2014. Several other owners have reported the exact same scenario on various Nissan forums. It is a wonder my wife and children were not in an accident.
