2000 GMC Envoy

On certain vehicles, the multifunction switch may develop an open circuit condition with the bottom contact of the hazard switch, causing the stop lamps and the hazard lamps to become inoperable (the center high mounted stop lamp and turn signal functions are not affected). The loss of stop lamp and rear hazard lamp function could fail to warn a following driver that the vehicle is braking and/or is stopped, which could result in a crash causing personal injury or death. Correction: Dealers will inspect and replace either the hazard warning switch, or the multifunction switch assembly. Note: This campaign expands the population of recall 2001285.
