I'd be driving down the street when my brakes would apply by them selves slowing my car down . after that my dash would bong and the ABS light would come on . I took it to my Chevy dealer and they replaced the brakes and said it was fixed . I pulled out of the dealers lot and was driving at 35MPH when the brakes locked and a skidded to a stop . If I hadn;t been buckled in I would have gone thru the windshield . I held the gas pedal to the floor and returnd to the dealer at about 20 MPH and some salesman came running out and said my van was on fire .I got out of my van but I didn't see any fire but there was heavy smoke coming from around the brakes . THE cHEVY DEALER HAD MY VAN APPROXIMATELY 7 MONTHS AND SAID THEY REPAIRED IT TWICE MORE , bUT EVERYTIME i PICKED IT UP THE BRAKES WOULD GO ON A SHORT DISTANCE AWAY AND i WOULD HAVE TO TAKE IT BACK . I have been driving the car because the chevy dealer says they can't get the ABS Module to fix it and I can't drive more than a mile or so from home because the brakes apply themselves and I'm afraid the car will break down or catch on fire . I need a safe car to drive and the chevy dealer says they can't fix it because they can't get the part .
