NHTSA lists 7 safety recalls covering the 2003 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.
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.
On certain crew cab pickup trucks and sport utility vehicles, the 2nd row center occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants, especially smaller occupants, seated in this position. Appropriate use of a child seat or booster seat, as recommended for…
Risk: A lap portion of the seat belt routing that is not low and snug on the hips can allow the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal an
On certain vans equipped with sure-lok wheelchair securement systems, the sprocket teeth of the retractor assembly is out of alignment.
Risk: In the event of a vehicle crash, the wheelchair may not be adequately secured possibly resulting in injuries to a wheelchair occupant.
Certain extended and regular cab pickup trucks and cargo vans converted to compressed natural gas (cng) fail to conform to the requirements of federal motor vehicle safety standard no. 225, 'child restraint anchorage systems.' these vehicles have one seating position, the center rear seat, equipped with child restraint lower…

On certain pickup trucks and sport utility vehicles, the galvanized steel tailgate support cables that retain the tailgate in the full open (horizontal) position may corrode, weaken, and eventually fracture. If both cables fractured, the tailgate would suddenly drop and strike the top surface of the rear bumper.
Risk: Anyone sitting or standing on the horizontal surface of the tailgate when both cables fractured could be injured by falling from the tailgate. On vehicles that have had the bumper removed, the tailgate may drop even lower. Additionally, if
Certain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? Some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.
Risk: Consequently, the valve o-ring seal may fracture. Steering efforts may be slightly increased while braking or parking. Under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to ach
Certain pickup trucks fail to conform to federal motor vehicle safety standard no. 212, "windshield mounting." some of these vehicles lack a continuous urethane bonding bead between the body surface and the windshield.
Risk: In vehicles with this condition, the windshield may not be retained in accordance with the safety standard during a vehicle crash.
