Vehicle description: passenger vehicles built with 3.5l engines. The fuel injection delivery system can leak fuel from some of the sealing o-rings or from hair line cracks in the thermoset fuel injection rail.
Risk and remedy
Risk: Fuel leakage in the presence of an ignition source can result in a fire.
Remedy: Dealers will replace the fuel rail o-rings and reinforce the outlet (passenger) side fuel rail. Vehicles showing fuel leakage on the outlet fuel rail must have the outlet rail replaced which includes changing the upper and lower injector o-rings. However, if a vehicle is leaking fuel from the o-rings or from a cracked fuel line, the vehicle should be taken into a dealer to have this repaired as soon as possible.
Vehicle description: passenger vehicles built with 3.3l engines. The 'o-rings' used to seal the interface of the fuel injector rail supply, return and cross over tubes are not as robust as those used in later model years. Deterioration of the 'o-rings' can cause fuel leakage.
Risk and remedy
Risk: In the presence of an ignition source, fuel leakage in the engine compartment could result in a fire.
Remedy: Dealers will replace the engine fuel rail.
Rear brake tube routing is contacted by fuel tank heat shield when suspension is in full jounce position. This damages the brake fluid tube, causing a leak.
Risk and remedy
Risk: Loss of fluid from half of the diagonally split brakehydraulic system affects braking capability, which could result in an accident.
Remedy: Modify heat shield to eliminate potential for shield contacting brake tube.
