While driving the brake lights came on and the brakes made a loud clunking noise. i had to slow down and stop and turn off the car. after conducting an inspection of the brakes, i restarted the car. the brakes were released and the brake light went off. this has happened several times since then, not only with me but also with my wife who was driving with my daughter in the vehicle too. after looking at the online forum (club armada) i determined that the vdc system needed reprogramming (according to all of the many other posts about the same incident). i'm here at the dealership now and it should cost about $100 to fix. we'll see..... *tr
