2000 GMC Sierra Problems, Complaints & Recalls

Problem: 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 surface of the tailgate when both cables fractured, they could fall and be injured. On vehicles without a bumper, the tailgate may drop to a lower position.

Fix: Dealers will replace the galvanized support cables with stainless steel support cables. In addition, dealers are to inspect the tailgate hinge and replace it, if necessary. The recall is expected to begin during april 2006. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Problem: 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, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin and the district of columbia only.

Risk: This can cause increased stopping distances during low-speed brake applications, which could result in a crash.

Fix: Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The recall began september 22, 2005. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Problem: 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.

Fix: Dealers will install a low-force spring clip retainer for vehicles equipped with a pbr parking brake system. On vehicles equipped with the trw parking brake system, dealers will install a redesigned parking brake cable assembly. The recall began on july 29, 2005. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Problem: 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. On certain vehicles equipped with hydro-boost power brakes, the same condition can result in loss of power assist for braking after the reserve pressure is depleted.

Risk: 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.

Fix: Dealers will replace the hydraulic pump. The campaign began on february 14, 2005. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Problem: 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 there is cargo on the tailgate the cargo may fall off if the support cables fracture.

Fix: Dealers will replace the cables. Interim owner notification began on april 7, 20004. The recall began on september 24, 2004, when replacement parts were available, and will continue through october 29, 2004. Owners should contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463, or visit www.mygmlink.com, and enter your vehicle identification number.

Problem: 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.

Risk: In a vehicle crash, front seat occupants may receive more severe injuries.

Fix: Dealers will recalibrate the sdm on the affected vehicles. Owner notification began august 28, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020 or gmc at 1-800-462-8782.

Problem: 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 of the brake system there can be a loss of brake fluid and pressure. The brake warning lamp will be activated when the brake fluid level reaches the indicator limit.

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.

Fix: Dealers will inspect the front right-hand brake pipe for wear. If there are signs of wear, this section of the brake pipe will be replaced with a new designed brake pipe section. If there are not signs of wear on the brake pipe, the dealer will install a spacer clip to ensure sufficient clearance between the brake pipe and the body cross sill.

Problem: 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. If misalignment occurs, eventually the abs would be non-functional.

Risk: The base brakes would remain fully functional, but the dynamic rear proportioning (drp) system, which optimizes front to rear brake balance, would become inoperative.

Fix: Dealers will replace the brake pressure module valve assembly.
