When the dealership disconnected our speed control (recall) the abs light came on and stayed on which eventually led to failure of the rear brake system. They would lock up while going down the road. We had to have the rear brakes and wheels rebuilt and spent over $1,000 on repairs. When the abs light came on immediately after disconnection of the cruise control the dealership check it out and said it would be fine. I have a hard time believing that this vehicle just developed a sudden brake issue that just happened to CO-inside with the disconnection of the cruise control. What is even harder to believe is that once it was fixed the brake light magically went off.
