2013 FREIGHTLINER M2
Check against the official notice below — it lists the full affected range.
Daimler Trucks North America is recalling certain 2013 Freightliner Business Class M2 vehicles manufactured between May 29, 2012, and June 11, 2012, that are equipped with compressed natural gas fuel tank systems made by Agility Fuel Systems. The recalled vehicles have a defect where the manual tank shutoff valve can become internally stuck in the closed position due to separation of the valve seat from the valve stem, even though the valve knob may appear to be open. This condition creates safety hazards including blocking fuel flow to the engine, preventing safe depressurization of the fuel system during service, and potentially causing fuel leaks and over-pressurization of the fuel container.
To remedy the defect, Daimler Trucks North America will notify owners, and Agility Fuel Systems dealers will replace the valve seat and stem assembly at no charge. The recall began in October 2014. Affected owners should contact Daimler Trucks North America customer service at 1-800-745-8000 or Agility customer service at 1-949-236-5520. Daimler's recall number for this issue is FL-669.

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.
DTNA will notify owners, and Agility Fuel Systems dealers will replace the valve seat and stem assembly, free of charge. The recall began in October 2014. Owners may contact DTNA's customer service at 1-800-745-8000 or Agility's customer service at 1-949-236-5520. DTNA's number for this recall is FL-669.
