2004 Chevrolet Express 3500 RecallsFuel Leak Due to Corrosion in Area Near Gas Cap
On vehicles equipped with a left side cargo door, water and road contaminants may become trapped in the protective conduit that covers the fuel filler pipe, which can cause the pipe to corrode. Significant corrosion may allow fuel to leak during refueling, and in the presence of an ignition source, this could cause a fire. Dealers will install a new fuel filler neck to correct this concern. The General Motors recall number is 12166.
On certain vans, the front and rear seat belts will not latch or unlatch. In a crash, the risk of injury is increased if the seat occupant is not properly restrained. Dealers will inspect the seat belt buckles, and will replace the buckle assembly if the buckle is found to be inoperative. If the buckle is found to function, only the upper buckle cover will be replaced. The recall began March 15, 2006. The GM recall number is 05113.
On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
