11/10/10 while driving the brake light came on and the truck was not responding to the brakes I heard a grinding noise and the problem went away after I turned the truck off and restarted it. It has happen like 4 times to my wife while driving with my kids so im very concerned about this problem. I went to the dealer and all they could say was that they needed to get the code for them to try to find out was wrong with it. If there's someone out there that can help before its too late and something serious happens.
