2003 Chevrolet Express 1500 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.

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.
