Recalls for the 2000 GMC Sierra: 12
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
Certain cequent 90 degree 7-WAY right angle adaptors sold by distributors in tow packages for aftermarket sales to tow 5th wheel RV travel trailers. Due to incorrect wiring of the harness, the trailer lights may not operate properly. If the trailer lights are not working properly, a vehicle crash can occur.
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. 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.
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 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. If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
Some pickup trucks, vans, and sport utility vehicles equipped with a hydraulic pump driveshaft that can fracture, resulting in immediate loss of hydraulic power steering assist. An inoperative pump can cause increased steering effort, and in hydro-boost equipped vehicles also increased braking effort, but does not completely eliminate the ability to steer or slow the vehicle.
Aftermarket pickup truck over-the-rail bedliners manufactured for installation on 1999-2004 Chevrolet silverado and GMC sierra pickup trucks. The toggle wing assembly used to attach the bedliner to the truck bed is not engaging fully in the stake pocket of the pickup truck. The bedliner can become detached from the pickup while it is motion, possibly endangering following motorists or pedestrians.
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. 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.
On certain pickup and utility trucks, some of these vehicles have an air bag sensing diagnostic module (SDM) which contains an anomaly that could result in the driver and passenger's air bag failing to deploy during certain frontal crashes. In a vehicle crash, front seat occupants may receive more severe injuries.
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. 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.
However, it is deemed a safety improvement campaign by the agency. Vehicle description: 1/2 ton light duty pickup trucks. This contact with the wheel rim could, in time, cause the brake hose to become worn to the point that brake fluid leakage could occur. If this occurred, loss of front brakes is possible.
Vehicle description: light duty pickup trucks equipped with 4-WHEEL disc brakes. Some of these vehicles have an antilock brake system (ABS) motor containing an out-of-specification spring clip. This clip could allow the motor bearing to become misaligned. The base brakes would remain fully functional, but the dynamic rear proportioning (Drp) system, which optimizes front to rear brake balance, would become inoperative.
