VIN may have been recalled. Check full report for more information
If the valve is stuck closed, the flow of fuel would be blocked from the fuel container to the engine. Such a condition poses a safety risk to service personnel as there is no safe way to depressurize the fuel system and service the subject valve when it is stuck in the closed position, increasing the risk of injury to the service personnel. There may also be a small fuel leak through the valve stem when the valve seat becomes detached, increasing the risk of fire. The affected fuel container may also become over-pressurized if the stuck valve goes undetected for a period of time, or is not repaired in a timely manner, and the ambient temperature increases significantly.
Daimler Trucks North America LLC (DTNA) is recalling certain model year 2013 Freightliner Business Class M2 vehicles manufactured May 29, 2012, to June 11, 2012, and equipped with certain compressed natural gas (CNG) fuel tank systems manufactured by Agility Fuel Systems. In the affected fuel systems, due to a separation of the valve seat from the valve stem, the manual tank shutoff valve can get internally stuck in the closed position while being opened, although the knob may indicate that the valve is open.
