2003 Ford F-150 RecallsPossible Corrosion of Fuel Tank Straps
Vehicles sold or currently registered in states using corrosive chemicals to de-ice the roads may have fuel tank straps that can rust prematurely and fail. If the fuel tank were to shift as a result of a broken strap, the fuel lines could separate or the fuel tank could contact the ground. In either case, a fuel leak could develop, increasing the risk of a fire. Dealers will replace the fuel tank straps with straps that have increased corrosion protection. Early in the campaign, if replacement straps are not available, dealers may install a cable support under the strap as an interim repair or a steel reinforcement over the existing strap as a permanent repair. This recall is expected to begin September 12, 2011. The Ford recall number is 11S21.
Ford has recalled 2003 Excursion and F150, F250, and F350 trucks because the speed control deactivation switch may leak and overheat, which can create a fire hazard. Dealers will install a fused wiring harness to the deactivation switch wiring.
Ford has recalled certain 2003 F150 trucks to inspect the retainer nut at the pitman arm where it mounts to the steering gear. On some trucks, the retainer may loosen, which can cause noise and lead to a possible detachment of the pitman arm. A loss of vehicle control could result. Dealers will tighten the pitman arm retainer nut to the appropriate specification.
