In certain environmental conditions, the fuel pump may vapor lock, causing the engine to stall. If this were to happen while moving, the driver would not be able to maintain speed or accelerate, increasing the risk of a crash. Dealers will install a resistor in the electrical line powering the fuel pump in order to prevent an occurrence of vapor lock. The recall began May 11, 2004.
