The 2000 GMC Sierra has 5 recalls, the most serious affecting 3500HD models where a steering drag link can fail to properly seat on the pitman arm, creating a loose connection in the steering linkage that can affect directional control.
Two other recalls involve safety systems. The airbag control module on certain trucks contains an anomaly that can prevent both front airbags from deploying in a frontal crash, leaving front-seat occupants with less protection. On trucks with four-wheel disc brakes, an out-of-spec clip inside the anti-lock brake system motor can allow the motor bearing to shift out of alignment, eventually disabling the ABS and the front-to-rear brake balance system, though the base brakes continue to work.
On the drivetrain side, a hydraulic pump driveshaft can fracture and cause power steering assist to disappear suddenly, requiring noticeably more effort to turn the wheel. On trucks equipped with hydraulic brake boosters, the same fracture can also reduce braking assist once the system's reserve pressure runs out. There is also a tailgate concern: the steel support cables that hold the tailgate open can corrode and snap under load, and the plastic sheathing around the cables can hide that corrosion until the cable breaks.
At a glance
What can fail
The hydraulic pump driveshaft can fracture, causing immediate loss of power steering assist. On some models with Hydro-Boost brakes, this also causes loss of power braking assist once reserve pressure depletes.
What the fix does
The hydraulic pump will be replaced at your dealer.

What can fail
The steel tailgate support cables can corrode and break over time, especially under load. If both cables fail, the tailgate drops suddenly and strikes the rear bumper. Someone on the tailgate could fall and be injured.
What the fix does
Dealers will replace the steel support cables with stainless steel cables that resist corrosion.

What can fail
The air bag sensing module contains a problem that could prevent the driver and passenger air bags from deploying during certain front-end crashes.
What the fix does
Dealers will recalibrate the air bag sensing module at no cost to restore proper air bag function.

At a glance
What can fail
The hole in the drag link that connects to the steering pitman arm may be drilled too deep, making it oversized. This prevents the pitman arm ball stud from seating properly, causing excessive friction. Over time, the joint may separate or the ball stud may break.
What the fix does
Dealers will inspect the steering linkage assembly and replace the drag link and pitman arm if necessary.

At a glance
What can fail
The antilock brake system motor contains a spring clip that may not meet specifications, causing the motor bearing to misalign. Over time, this misalignment can make the antilock braking system stop working.
What the fix does
The dealer will replace the brake pressure module valve assembly.
