Contact states: at very low speed anti lock brakes would kick in when consumer would brake instead of braking the vehicle would keep moving, it doesn't matter what the weather condition is. It has been repaired at contact's expense. Contact called gm, they said it needed two new hubs, including the bearings (left and right). Gm covered 1/2 of the cost.
