Brake Sensor problems of the 2013 Chevrolet Equinox

Me and my wife own a 2013 chevy Equinox. We have had this vehicle for about 18months and purchased this brand new. While driving at various speeds, the foward collision sensor activated independently without any other vehicle within close proximity. Myself and my wife have both had this problem. It happens to her all the time since she is the primary driver. She has had this happen to her over 20 times in the past 1. 5 yrs. Forward collision warning will go off with no vehicle in front of her and then the brakes will momentarily engage. I have drove the vehicle and had this happen twice. I have been in the vehicle as a passenger on (3) occassions when this happened. We have had this SUV for 18months and she has taken it to (2) dealerships. Both stated they have no idea what is causing this and told us to DE-activate the system. Why have this safety feature and you are told to turn it off by dealership because they have no idea on how to fix it?? I dont even know if they have contacted Chevrolet to inquire. Dealerships we utilized were john jones from corydon, in and coyle Chevrolet located in clarksville, in. This is a safety feature but has become a safety issue. I have done research online and have found countless other owners that are having the same problem.
