NHTSA lists 2 safety recalls covering the 1998 GMC Sierra. Open recalls don't stop you from selling or junking the car, but check your VIN at nhtsa.gov/recalls to see which apply to yours.
Vehicle description: crew cab pickup trucks. The front, inner corner of the fuel tank can contact the body sill either intermittently or constantly. This movement can cause a discernible noise and, over time, can wear a hole in or crack the fuel tank at point of contact.
Risk: This condition can result in fuel leakage and a distinct fuel odor if the tank were filled above the level of the hole or crack. In the presence of an ignition source, a fire could result.
Vehicle description: light duty pickup trucks and multi-purpose passenger vehicles. One or both front brake rotor/hubs were built with an out-of-specification gray iron that can fail during the life of the vehicle.
Risk: If a driver continues to drive with a cracked rotor, the cracks could continue around the wheel mounting bolt circle and ultimately result in a wheel separation.
