On certain vehicles, variations in the manufacturing process or exposure to high ambient temperatures may lead to fracture of the fuel tank inlet check valve (icv).
Rischio: A fracture may allow fuel vapors to pass through and allow droplets of fuel to accumulate on the side of the fuel tank. Fuel leakage, in the presence of an ignition source, could result in a fire.
Rimedio: Dealers will replace the fuel tank. The recall will be mailed in two phases with the first phase beginning on december 4, 2007. The second phase will be mailed on december 13, 2007.
