Adaptive Equipment problems of the 2008 Saturn VUE

Our 2008 Saturn Vue xe recently started locking up the abs and brakes while driving. It happens in stop and go traffic and most frighteningly at freeway speeds. The vehicle will apply the brakes at will for no reason and the abs and traction control indicators come on. We have had the vehicle serviced multiple times and we have replaced all brake hardware and the issue still exists. We have done countless hours of research and have found that hundreds of Saturn, Chevrolet, and commodore vehicles exhibit the same issues and general motors dealerships do not even have an answer. The vehicle brake issues render the vehicle inoperable and cause immediate slowness and inability to maneuver on the freeway when it locks up. We cannot use the vehicle and have exhausted all resources and options trying to fix the issue. It cannot be traded in with these issues either. Can somebody investigate possible recalls or dealer solutions so we can feel safe driving. . . With or without our small children. Please help.
