Warning lights for anti-lock brakes, brakes, and traction control come on and off randomly. Anti-lock brake feature is disabled when light is on. Brake performance is greatly reduced sometimes while warning lights are on. Traction control does not function when light is on. Dealer said GM had issued a service bulletin for corrosion in a wiring harness plug leading to the wheel rotation sensor. Dealer stated replacement wiring harness was $500. Dealer tried cleaning contacts on plug and applying conductive corrosion preventing. Did not fix problem. Severe safety issue when anti-lock feature is deactivated, traction control deactivated, and brake performance is reduced. Developed problem in December 2006.
