NHTSA lists 6 safety recalls covering the 1999 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.
Certain pickup trucks have galvanized-braided-steel tailgate support cables used to support the tailgate in the full open (horizontal) position. Over time these cables can corrode and fracture when loads are applied to them.
Risk: If one cable fractures, the remaining cable may retain the tailgate in a horizontal position. If both cables fracture, the tailgate would drop and strike the top surface of the rear bumper. If anyone is sitting or standing on the horizontal
Certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (ABS) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan…
Risk: This can cause increased stopping distances during low-speed brake applications, which could result in a crash.
On certain pickup trucks equipped with manual transmissions and built with either pbr parking brake systems or trw parking brake systems, the parking brake friction linings may wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.
Risk: If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
Vehicle description: light duty pickup trucks and sport utility vehicles. Some of these vehicles have a clearance condition between the front right-hand brake pipe and the body cross sill that could decrease to the point of allowing contact during the life of the vehicle. If contact occurs and the brake pipe becomes damaged, in half…
Risk: During braking, the pedal will be lower than normal and stopping distances will be longer. If this occurs when stopping distance is limited, a crash could occur.
Vehicle description: light duty pickup trucks and sport utility vehicles. These vehicles do not comply with the occupant protection requirements of fmvss no. 208, "occupant crash protection."
Risk: In the event of a vehicle crash, the right front passenger restraint systems may not meet the neck extension requirements.
Vehicle description: extended cab 4-wheel drive pickup trucks. Some of these vehicles have a lower than specified torque on all three of the steering gear to frame attachment bolts. The bolts can loosen over time allowing the steering gear to move. This loosening can result in some unresponsive steering feel and some noise to the…
Risk: If this condition is ignored, the steering gear to frame can wear and/or fatigue the attaching bolts to the point of breakage or the bolts backing out. If all the bolts break or back out, the steering gear would separate from the frame resu
