On certain vehicles, cracks may develop between the fuel delivery module filter housing and cap, causing a low fuel pressure condition. Low fuel pressure could result in engine stalling, reduced engine power, extended cranking and/or no-start condition. This could increase the risk of injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will replace affected fuel delivery modules.
On certain compressed natural gas (CNG) fuelled vehicles, the CNG high pressure regulator may leak natural gas. Should a leak occur in the presence of an ignition source, a fire or explosion could result, increasing the risk of injury and/or damage to property.
On certain vehicles, a particular type of spider may weave a web in the evaporative canister vent line which may cause a restriction in the line. If this occurs, the fuel tank pressure may become excessively negative when the emission control system works to purge the vapors from the canister. As the canister is purged repeatedly during normal operation, the stress on the fuel tank may eventually result in a crack causing a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the canister vent line and replace it with a line containing a filter. If a web is found in the old line, the fuel tank will also be replaced
On certain vehicles, deposits may collect on fuel pump connections and reduce fuel pump performance. This could cause the engine to stall, resulting in a loss of motive power and increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will update vehicle software to increase fuel pump pressure in order to prevent deposits from forming.
On certain vehicles, the fuel line was improperly manufactured, which could result in a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or property damage.
On certain vehicles, the fuel tank may have been manufactured incorrectly and could allow fuel to leak from the tank pinch seam. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or property damage.
On certain scooters, an improper installation of the fuel hose and hose clamp to the vehicle's carburetor could result in the fuel hose disconnecting during use and fuel leaking onto the vehicle's engine. Fuel in the presence of an ignition source may result in a fire.
Safety Risk
No risk description available.
Remedy
Retailers will inspect and re-install the fuel hose properly, as necessary.
On certain HD vehicles equipped with a diesel engine and dual fuel tanks, the fuel pipe tube nuts on each side of the diesel fuel transfer pump may not have been properly torqued. As a result, diesel fuel may leak at the fuel transfer pump if there is fuel in the rear tank and the transfer pump activates to transfer fuel to the forward fuel tank. Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or injury.
Safety Risk
No risk description available.
Remedy
Dealers will tighten the tube nuts to the proper torque.
On certain motorcycles, due to a defect in the fuel level indication system, the engine may run out of fuel when the fuel range indicator shows that there are still kilometers remaining, and in some cases before the low fuel warning lamp illuminates.
