The 1991 GMC Jimmy has 6 recalls, the most serious being a fuel tank sender seal that can sit out of position and allow fuel to spill during a rollover, creating a fire risk if that fuel reaches an ignition source.
Windshield and side window glass bonding is also a concern: the adhesive primer used on the window openings may not hold the glass securely, meaning the windshield or side windows can give way in a crash and fail to keep occupants inside the vehicle. On the restraint side, the rear seat belt buckles on 4-door models can develop a problem where the buckle assembly shifts inside its cover, causing the release button to stick in the unlatched position. When that happens, the belt cannot be latched at all, leaving rear-seat occupants without a working restraint if a crash occurs. The anti-lock brake system on 4-wheel drive models equipped with ABS can also malfunction in a way that reduces braking effectiveness, potentially extending stopping distance without any warning to the driver, which raises the risk of a collision when hard braking is needed most.
