Chevrolet Silverado 2500 Recalls
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.
The Antilock brake system pump motor may have an insufficient spring clip installed, which may cause an internal bearing retention issue. This could affect pump motor operation, and may cause brake pressure differentiation issues between the front and rear brakes. Dealers will replace the brake pressure module valve assembly.
