On certain scooters, should the fuel tank be overfilled, or the motorcycle be tipped-over on it's side, raw fuel may be allowed to enter the hoses of the evaporative emissions system. This could cause a litany of drivability concerns including: difficulty starting, random stalling, low power, reduced top speed, float bowl overflowing, etc. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the rider's reactions, could increase the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealers will re-route emission system hoses and replace the "Hose Routing Diagram" sticker.
On certain trucks, incorrect software installed during vehicle assembly will cause the Diesel Particulate Filter (DPF) inhibit function to be disabled. As such, the driver may not be able to stop, or be aware that, DPF regeneration is occurring. Should this happen while the vehicle is in a location that presents a hazardous situation, it could result in a fire.
Safety Risk
No risk description available.
Remedy
Dealers will change electronic module control parameters.
Certain vehicles do not comply with the requirements of CMVSS 1101 - Emission Device. The Injector Pressure Sensor (IPS), located on the end of the fuel rail, may become contaminated with water during shipping to the assembly plant. This water could freeze in low ambient temperatures and cause the IPS membrane to crack or burst, resulting in possible illumination of the Malfunction Indicator Light (MIL), engine no start and internal engine damage due to hydro-locking.
Certain vehicles equipped with LPG or CNG fuel systems do not comply with the requirements of CMVSS 1101 - Emission Device. The Malfunction Indicator Lamp (MIL) may illuminate when no problem exists, or not light when one does.
Safety Risk
No risk description available.
Remedy
Dealers will install (reflash) the proper Powertrain Control Module (PCM) calibration.
Certain vehicles equipped with a 3.5L engine do not comply with the requirements of CMVSS 1101 - Emission Device. These vehicles were built with incorrect emission control labels.
Safety Risk
No risk description available.
Remedy
Dealers will install a new vehicle emission control label on the radiator support.
On certain vehicles, the crankshaft position sensors may fail and cause an intermittent engine chuggle, stall or possible long starting crank time and/or a no-start condition, as well as illumination of the Malfunction Indicator Lamp (MIL).
Safety Risk
No risk description available.
Remedy
Dealers will replace both crankshaft position sensors.
Certain vehicles do not comply with the requirements of CMVSS. 1105 - Evaporative Emissions. Vehicles may have an OBD-II (On Board Diagnostics) calibration that causes a false evaporative emission system code to set under certain conditions, resulting in Malfunction Indicator Lamp (MIL) illumination.
Safety Risk
No risk description available.
Remedy
Dealers will reflash the vehicle PCM (Power Control Module) with new calibration software.
Certain vehicles do not comply with the requirements of CMVSS. 1103 - Exhaust Emissions. The average CO of the subject vehicles may exceed the standard due to insufficient robustness of emission control logic, and calibration of emission parts with extended usage.
Safety Risk
No risk description available.
Remedy
Dealers will install an engine intake kit, which will allow additional air to enter the engine, improving combustion efficiency and lowering the levels of carbon monoxide.
Certain V6 Rodeo do not comply with the requirements of CMVSS 1105 - Evaporative Emissions. The rubber purge hose of the Enhanced Evaporative Emission Control System (EVAP) may crack, due to proximity of the exhaust pipe.
Safety Risk
No risk description available.
Remedy
Dealers will install an EVAP pipe and hose assembly using a clearance template, and will inspect routing clearances after installation.
On certain vehicles equipped with 3.0 litre engines, the Vehicle Emission Control Information (VECI) labels are those required by the US federal standard.
Safety Risk
No risk description available.
Remedy
The correct VECI label, along with installation instructions will be mailed to owners.
Certain CNG vehicles do not comply with the requirements of CMVSS 1105 - Evaporative Emissions. The natural gas fuel fill valve may leak due to flaking of the nickel plating inside the valve. This will allow natural gas to escape into the atmosphere at a rate that exceeds the limits prescribed in the standard.
Safety Risk
No risk description available.
Remedy
Valve will be replaced with one of an alternative design.
On certain Mustang GT vehicles equipped with 4.6 litre, 2-valve engines, the transmission control wire harness may chafe against the EGR tube and sleeve possibly damaging the harness convolute and wires. This damage could cause powertrain and emission control concerns such as illumination of the Malfunction Indicator Lamp (MIL), engine not starting and the transmission failing to upshift.
Safety Risk
No risk description available.
Remedy
Transmission harness will be inspected for damage and repaired or replaced and rerouted as necessary.
Certain vehicles may not comply with the requirements of CMVSS 1105 - Evaporative Emissions. Fuel vapour may leak from between the fuel cap and the fuel filler pipe.
Safety Risk
No risk description available.
Remedy
Filler cap will be replaced with one that incorporates an o-ring that will positively seal the suspect fuel filler pipes.
Certain vehicles do not comply with the requirements of CMVSS 1101 - Emission Device. Vehicles were built with incorrect emission control labels. The emission control (tune up) labels have an incorrect emission vacuum hose routing schematic.
Safety Risk
No risk description available.
Remedy
Dealers will install a new vehicle emission control label on the radiator support.
Certain vehicles equipped with the 5.9L Heavy Duty gasoline engine do not comply with the requirements of CMVSS 1101 - Emission Device. The emission system was not correctly programmed within the Powertrain Control Module (PCM) and the Emission Maintenance Reminder Light (EMR) does not illuminate as required.
Safety Risk
No risk description available.
Remedy
The PCM will be reprogrammed (reflashed) with the proper EMR light calibrations.
Certain vehicles equipped with 4.8 litre or 5.3 litre engines do not comply with the requirements of CMVSS 1103 - Exhaust Emissions. Engines may have been built with the wrong Linear Exhaust Gas Recirculation (LEGR) valve which could limit the required air flow rate. A failed valve could cause the vehicle to fail to meet applicable emissions standards.
Safety Risk
No risk description available.
Remedy
Vehicles will be inspected and LEGR valve will be replaced with a new valve where required.
Certain Spirit and Acclaim with a 2.5 litre flex-fuel engine and Intrepid with a 3.3 litre flex-fuel engine do not comply with the requirements of CMVSS 1101 - Emission Device. The methanol fuel sensor may fail due to grounding of the circuit board and a software problem.
Safety Risk
No risk description available.
Remedy
An improved methanol concentration sensor will be installed on affected vehicles.
Certain full size pickups equipped with the Cummins Encore 24 valve diesel engine do not comply with the requirements of CMVSS 1103 - Exhaust Emissions. The fuel management system which advances fuel injector timing for better steady highway fuel economy, also increases the NOx emissions.
Certain vehicles do not comply with the requirements of CMVSS 1101 - Emission Device. Vehicles may have been built with a Vehicle Emission Control Information (VECI) label that has an inaccurate evaporative hose routing.
Safety Risk
No risk description available.
Remedy
A correct VECI along with installation instructions will be mailed to involved vehicle owners. Dealers will be instructed to assist owners needing help with label installation.
