I have had this reoccurring experience off and on more than 10 times for at least the past 4 years. There is no known pattern of occurrence. It happens sometimes while I am driving and all of a sudden I hear popping or crunching noises below the vehicle and then the brake indicator light on the dash board will turn on. Then I feel I am loosing the ability to stop the vehicle as I carefully move over to the shoulder of the road with brake indicator light and popping noise still on. Due to this problem, my wife have stopped using this vehicle. Once safely off the road, this problem is often resolved by turning off and on the ignition and all will be well until the next occurrence. However, after yesterday's (09/27/2014) occurrence which was very scary, I called our nearest Nissan dealer and scheduled to have the vehicle inspected next Tuesday (10/01/2014). Out of curiosity, I decided to research this problem on the internet and was surprised to find hundreds of Armada owners with a similar problem and sense of helplessness with Nissan's reluctance to acknowledge this problem. I feel action should be taken immediately to address this potentially dangerous problem before someone losses their life.
