Recalls for the 2003 Toyota 4Runner: 3
The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.
On certain sport utility vehicles equipped with V6 engines, the fuel pulsation damper, located on the fuel rail, may have been improperly assembled, causing a diaphragm in the pulsation damper to be damaged. If the diaphragm fails, fuel may leak. This could result in an engine compartment fire if a heat source or an ignition source is present.
On certain sport utility vehicles equipped with five factory alloy wheels (Model 6934 and 6936), with factory llat, and with port installed WR4, four alloy wheel upgrade processed at the jacksonville, florida port and distributed by southeast Toyota distributors in the states of alabama, florida, georgia… If the spare tire/wheel is installed on the vehicle using the wheel nuts provided for the upgrade alloy wheel, damage to the wheel could result and could eventually lead to a loose wheel.
