RepairPal Expert Overview:
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.
