Abs activation at low speed and then abs holding up. I almost got into 3 accidents with small children in car. I have replaced brake pads, rotors, abs sensors, calipers, brake lines and brake switch. Nothing works. Front tire area catches on fire if driven for long distances. Hard time stopping. Gm will not recall or repair. There is a TSB (020525006) on same problem but not for my state. Recall in other parts of country for same problem, but gm states not for my state even though it is for same problem. Very dangerous to drive.
