Front Seat Belt Anchorage problems of the 2001 GMC Sierra

Brakes will go out while driving, and the pedal will go to the floor before the vehicle even starts to slow down. Contacted the dealer, and the dealer is not willing to do anything. The consumer states that the ride control will not go on; there is an internal short-replaced the ride control, the consumer states that the abs light stays on-faulty speed sensors, and right front seat belt is not retracting.
