National Highway Traffic Safety Administration Recall (Jan 07, 2005)
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.
Consequence
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.
Resolution
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.
