The hydraulic pump that controls power steering and in some cases hydro-boost power brakes may experience a fracture of its driveshaft. If this shaft breaks, power steering assist will cease immediately and hydro-boost brake power will also cease following depletion of stored reserve pressure. An increase in steering and brake effort may cause an accident. Dealers will replace the hydraulic pump.
Chevrolet Silverado 1500 Recalls
The bolt attaching the intermediate steering shaft to the steering gear may break, resulting in loss of steering ability, increasing the risk of a crash. Dealers will replace the intermediate shaft bolt to correct this concern. This recall is expected to begin on January 24, 2005. The General Motors recall number is 05010.
The engine fuel rail crossover tube retainer screws may not have been manufactured to specifications and can break. If the retainer screws break, fuel could leak from the crossover joint.

Owners were contacted by telephone beginning July 30, 2004. The General Motors recall number is 04066.
The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.
On 110 vehicles, the windshield may not have a full bead of urethane bond to the body surface. This is against the Federal Motor Vehicle Safety Standard and the windshield may not be retained during a crash. Dealers will remove, reseal, and reinstall the windshield. The recall began January 28, 2003. The GM recall number is 03001.
The air bag diagnostic module may contain a flaw that will prevent deployment of the air bags during a collision. This may result in severe injuries sustained by occupants during a collision. Dealers will recalibrate this module to correct the flaw.
The tire size and inflation pressure for the vehicle may be incorrectly listed on the certification label. Dealers can verify and install the proper label free of charge to correct the concern.
