- Summary
- 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.
- Remedy
- 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.
