On certain vehicles, a weld on the fuel tank may be insufficient, resulting in a fuel leak. If this were to occur the operator may notice a strong fuel smell and some dampness on the ground. If a sufficient amount of fuel were to leak out and if an ignition source were present, a vehicle fire could occur.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the fuel tank, and replace, if necessary.
On certain vehicles, the fuel pump impeller may be deformed by alcohol included in fuel, causing the impeller to contact the fuel pump body. This condition could increase the rotation resistance of the impeller and, in the worst case, the fuel pump may lock, which may result in the engine stalling.
On certain vehicles equipped with an 8-cylinder engine, the circular retention clip at the quick-release coupling along the fuel supply line was inadvertently omitted. As a result, it is possible that in a severe frontal crash, the quick-release coupling could separate. If this happens, a small amount of fuel could leak and potentially ignite.
On certain Saturn Ion Red Line vehicles equipped with the supercharged 2.0L engine, the fuel feed pipe may crack near the fuel rail, which would result in a fuel leak and a noticeable fuel odour around the vehicle. If an ignition source is present, a fire could result.
On certain vehicles, the fuel cut valve at the fuel tank may not close properly. If a vehicle with a defective fuel tank assembly cut valve were to roll over, fuel spillage could occur. Fuel spillage in the presence of an ignition source may result in a fire.
Safety Risk
No risk description available.
Remedy
Dealers will install an additional fuel cut valve.
On certain motorcycles, if the plastic fuel pump flange comes into contact with a sufficient amount of acid or chemical compounds containing acidic elements, such as battery acid or certain cleaning products, the flange may become brittle. Over time, the flange may crack, and eventually allow fuel to escape from the fuel tank.
Safety Risk
No risk description available.
Remedy
Dealers will install an acid-resistant cap over the fuel pump flange.
On certain vehicles, the fuel pump terminal on the fuel sending unit can develop a crack. When exposed to heavy concentrations of road salt in the winter, if road salt enters the crack, the terminal strip will corrode and eventually could break due to corrosion. This will cause the fuel pump to stop operating and will result in not being able to start the engine or cause the engine to stop running without warning.
On certain vehicles, a fuel vapour tube hose clamp may not be positioned properly. The spring-type hose clamp contains ears that may be squeezed together with a tool to increase the diameter of the clamp to allow it to be installed on the vapour tube hose. Hyundai's specification requires the vapour tube hose clamp ears to not be directed toward the fuel tank. If a vehicle contains a vapour tube hose clamp that is mispositioned so one of its ears is facing toward the fuel tank and that vehicle is involved in a severe high speed crash, the damage to the vehicle may cause the mispositioned clamp ear to damage the fuel tank and fuel spillage may occur. Fuel spillage in the presence of an ignition source may result in a fire.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the position of the vapour tube hose clamp ears and will correctly position the clamp, if necessary.
On certain motorcycles, the male fuel connector linking each of the feed and return fuel hoses to the fuel pump mounting plate may be found to contain a fracture following in-service handling. Fuel could escape from the fractured body of the connector onto the engine or side of the bike. Fuel leakage, in the presence of an ignition source, can result in a fire.
On certain vehicles, localized depressions in the fuel tank wall at the seam between the top and bottom halves of the tank may allow fuel to permeate resulting in a fuel odour, and/or a Malfunction Indicator Lamp (MIL) illumination.
On certain vehicles, stress cracks can be initiated in the plastic fuel tank at the vent valve welding ring, the breather pipe weld or at the filler pipe stub. Owners may notice a fuel smell emanating from their vehicle. If these cracks continue to propagate, fuel leakage could result. Fuel leakage in the presence of an ignition source could result in a fire.
Safety Risk
No risk description available.
Remedy
Dealer will replace the fuel tank with one of an improved design.
On certain vehicles, the fuel tank assembly valve may not close properly. If a vehicle with a fuel tank assembly valve that is not properly closed were to roll over, fuel spillage could occur. Fuel spillage in the presence of an ignition source may result in a fire.
Safety Risk
No risk description available.
Remedy
Dealer will install an additional fuel tank assembly valve.
Certain vehicles contain a defect involving the electric fuel pump. Under certain environmental conditions, for example, driving during high outside temperatures in combination with high altitudes (over 5,000ft.), vapor lock in the fuel pump could occur. This could cause the engine to stall. If this were to happen, the engine could be unable to be restarted for approximately 15 to 20 minutes.
Safety Risk
No risk description available.
Remedy
Dealer will install a resistor in the electrical line leading to the fuel pump. This will reduce the power output of the fuel pump and preclude an occurrence of vapor lock.
On certain vehicles, the potential exists, following disconnection, for the quick connector not to be fully re-engaged. This would eventually result in a loss of fuel that, in the presence of an ignition sources, creates a risk of a vehicle fire. Disconnection is a requirement for some service operations.
Safety Risk
No risk description available.
Remedy
Dealer will remove the quick release collar, ensure full engagement and fit a safety clip.
On certain vehicles, the ground connection between the spiral ring of the fuel tank filler neck and the connecting pipe to the tank is not sound. If this ground connection is inadequate, the flow of fuel when refuelling can create and electrostatic charge and a spark which could ignite fuel vapours.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the ground connection and, if necessary, correct it.
On certain motorcycles, the crimp-type hose clamps along the fuel line may not have been installed properly and could leak. Fuel leakage in the presence of an ignition source could result in a fire.
Safety Risk
No risk description available.
Remedy
Dealer will inspect, and if necessary, adjust all crimp-type hose clamps.
On certain motorcycles, the accelerator pump diaphragm may be damaged by excessive assembly clamping pressure, thus allowing fuel to leak from the pump actuating rod area. Fuel leakage in the presence of an ignition source could result in a fire.
Safety Risk
No risk description available.
Remedy
Dealers will replace the accelerator pump diaphragm.
On certain vehicles, the rubber section of the fuel lines could deteriorate and disconnect from the metal fittings, causing a fuel leak which may result in a fire in the engine compartment.
Safety Risk
No risk description available.
Remedy
Dealer will replace the fuel lines and attachments.
On certain vehicles, the fuel filter assembly may corrode prematurely on the exterior surface. If corrosion on the exterior surface of the fuel filter assembly progresses to the point of creating a hole in the shell, fuel droplets would form and drop to the ground. There would be a noticeable fuel odour around the vehicle. If an ignition source is present, a fire could result.
