The 2000 GMC Jimmy has 4 recalls, the most serious affecting 2-wheel-drive models where brake fluid can leak from the anti-lock brake system, increasing stopping distances.
The brake concern stems from ABS feed and crossover pipe fittings that may not have been fully seated, allowing them to work loose and leak fluid as the brakes are used over time. Even a partial loss of fluid pressure lengthens the distance the vehicle needs to stop, which reduces the margin in an emergency. The remaining recalls all describe the same underlying problem with the multifunction switch, which can develop an internal break in the hazard switch carrier circuit. When this happens, the rear brake lights and hazard lamps stop working, while the center high-mounted brake light and turn signals continue to function normally. A driver following the Jimmy would have no visual warning that the vehicle is braking or stopped, raising the risk of a rear-end collision.
