On certain vehicles, the fuel lines may weep or leak fuel due to an error in the assembly process. Fuel leaks may potentially occur at any location along the fuel line due to the introduction of foreign particles between the metal fuel line and plastic fuel line during the connection process. This could cause scratches on the plastic fuel line portion, and over time can increase the risk of an underhood fire causing injury and/or property damage.
On certain vehicles, an underhood fuel connector may not have been securely attached to the fuel supply line and could result in a fuel leak into the engine compartment. A fuel leak, in the presence of an ignition source, could create the risk of a fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the fuel line connection and ensure it is securely attached.

Remedy
Dealers will inspect the fuel line connection and ensure it is securely attached.
On certain vehicles, fuel may weep or leak from one of the lower connecting points of the fuel hose. If this occurs, a fuel odour may be detected inside the vehicle. Fuel leakage, in the presence of an ignition source, could increase the risk of fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the hose and clamp at the lower connecting point of the transition hose, between the underbody fuel line and the Schrader valve, and replace the hose at the upper connection of the fuel line to the fuel pump.
Certain vehicles with a cracked (but not leaking) fuel pump flange were repaired with butyl tape only under a previous recall (please see Transport Canada Recall 2016-443 / Audi campaign 20W9). This is because replacement fuel pump flanges were not available at the time of repair (the butyl tape was used an interim repair). If the fuel pump flange is not replaced, a fuel leak could still occur. A fuel leak, in the presence of an ignition source, could lead to a fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace fuel pump flange and reapply the protective butyl tape.
On certain vehicles, the low fuel warning light may not turn on at the correct time to warn of a low fuel level. The driving range indicator in the multi-information display may also indicate a remaining distance-to-empty when the fuel tank is empty. While the low fuel warning light will eventually turn on and the fuel gauge will eventually display “E” (empty), if the driver continues to operate the vehicle based on the range indicator, the vehicle may run out of fuel, causing the engine to stall and increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the combination meter (gauge cluster) software.
On certain vehicles, the Canister Purge Valve (CPV) may stick open and cause excessive vacuum in the fuel system that could deform the fuel tank. If this were to occur, it could cause: a malfunction indicator light (MIL) to illuminate, erratic readings on the fuel gauge, and/or the engine may stall. This could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the Powertrain Control Module (PCM) with new software and replace the CPV as necessary. If the CPV is replaced, dealers will inspect and replace the carbon canister, fuel tank and fuel delivery module as necessary.
On certain 4x2 flex fuel (E85) vehicles equipped with a 2.4 L engine, a problem with the fuel pump could cause a loss of fuel pressure under certain operating conditions. This may lead to an engine stall, resulting in a sudden loss of motive power, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the fuel pump with an updated part.
On certain motorcycles, the fuel pump O-ring may have been twisted during installation and may not seal properly. This could result in a fuel leak, which in the presence of an ignition source, could increase the risk of fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the fuel pump O-ring and fuel tank inner vessel with improved parts.
On certain trucks built with a Cummins X15 or ISX15 engine equipped with nylon fuel lines and a banjo bolt on the fuel pump, a blockage in the fuel cooling system may cause a fuel line to burst. This could result in a significant fuel leak onto the roadway, which would create a road hazard for other motorists. Additionally, this condition could also cause an engine stall without warning, without the ability to restart the engine. Both of these conditions may increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Cummins-authorized dealers will replace the affected nylon line with a steel line.
Certain vehicles may have been built with a defective fuel tank crossover pipe connecting the left and right tanks. Over time, the crossover pipe could separate and cause a fuel leak which, in the presence of an ignition source, could create the risk of a fire causing injury and/or damage to property.
On certain vehicles, a crash protection plate was not installed beside the high pressure fuel pump in the engine compartment. In the event of a severe crash, the high pressure fuel pump could become damaged and cause a fuel leak, which in the presence of an ignition source, could result in a fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will install the missing crash protection plate.
On certain BMW M5 models, the fuel level sensor may contact an in-tank fuel line, causing the fuel gauge to display an incorrect fuel level. This may create a situation where the vehicle could run out of fuel while the gauge still displays that there is fuel remaining. As a result, the engine could stall without warning and increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will secure the fuel line so that it does not contact the fuel level sensor.
On certain vehicles equipped with a 3.5L V6 engine, the fuel pulsation dampers located in the fuel delivery pipe could develop a leak over time. A fuel leak in the presence of an ignition source could increase the risk of fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the fuel delivery pipe with an updated part.
On certain vehicles, the fuel supply line for the high pressure fuel pump may become porous over time. This could cause a fuel smell or a fuel leak, which in the presence of an ignition source, could result in a fire causing property damage and/or personal injury.
On certain vehicles, the high-pressure fuel pump may have been improperly manufactured and could fracture at its mounting flange. This could cause an oil or fuel leak which, in the presence of an ignition source, could increase the risk of fire, causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the high-pressure fuel pump, high-pressure discharge tube and mounting bolts.
On certain motorcycles, the airbox blow-by and fuel tank overfill hoses could melt, as they may be too close to the horizontal exhaust manifold. If a hose melts, it could cause a fuel leak which, in the presence of an ignition source, could increase the risk of fire, causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will re-route the hoses to ensure they are away from the exhaust manifold.
On certain vehicles, a joint on the high-pressure fuel pump may have been improperly welded during the manufacturing process. Over time, this could cause the weld to crack and create a potential fuel leak. A fuel leak in the presence of an ignition source could increase the risk of fire, causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the high-pressure fuel pump and high-pressure fuel pipe.
On certain BMW M5 models, an error in the engine control unit software may cause the fuel pump to stop working. This could cause the engine to stall, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will update the engine control unit software.
On certain vehicles, the thickness of fuel tank walls may not be adequate due to an issue in the manufacturing process. This could result in fuel leaking from the tank, which in the presence of an ignition source, could result in a fire causing property damage and/or personal injury.
