Recall 14V589 affects 16 2013 Freightliner M2 trucks for a CNG tank shutoff valve defect. Repair is free at any franchised Freightliner dealer.
Freightliner is recalling 16 2013 M2 trucks because a CNG tank shutoff valve can appear open while stuck closed, blocking fuel flow to the engine. The stuck valve creates a service risk when the fuel system cannot be safely depressurized, and a detached valve seat can raise fire or over-pressure risk; the dealer repair will be free once available.

What's wrong?
The compressed natural gas (CNG) fuel tank system on the 2013 Freightliner M2 stores fuel under pressure and feeds it to the engine through tank valves and fuel lines. The manual tank shutoff valve is the hand-operated valve that opens or closes fuel flow from the tank. When the valve is open, CNG is supposed to leave the tank and move through the fuel system.
In this recall, referenced from NHTSA campaign 14V589, the valve seat can separate from the valve stem inside the shutoff valve. That separation lets the valve become stuck closed while someone is opening it. The outside knob can still look like it is in the open position, so the valve indication does not match the actual fuel flow.
There is no warning sign before failure. The owner or service technician can believe the tank valve is open even though the valve is closed internally, leaving the truck without the expected CNG supply from that tank.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
A stuck fuel valve can block fuel flow to the engine and leave service personnel without a safe way to depressurize the system before repair, increasing injury risk. A detached valve seat can also let fuel leak through the valve stem, increasing fire risk, and overpressure can build in the fuel container. Repair will be free at any franchised Freightliner dealer once available.
What should I do?
- Check your VIN to confirm your 2013 Freightliner M2 is included in this recall.
- Contact a franchised Freightliner dealer and ask about the free CNG shutoff valve-seat and stem assembly replacement.
- Reference recall number 14V589 when you call, and mention that the CNG tank shutoff valve can get stuck closed while the knob reads open.
- Bring the recall notice if Freightliner sent one, plus any service records tied to the CNG fuel tank system.
- Keep service work on the CNG fuel system to qualified repair personnel until the valve repair is complete.
What happens at the repair
At the dealer, a Freightliner technician replaces the valve seat and stem assembly in the compressed natural gas fuel tank system. That repair addresses the manual tank shutoff valve that can appear open at the knob while staying internally closed. The final dealer repair will be free once available, with parts and labor covered under recall 14V589. The filing says owner notices began in October 2014, so ask the dealer to confirm the campaign and parts handling before the visit.

Frequently asked questions
What is recall 14V589?
Recall 14V589 covers 16 2013 Freightliner M2 vehicles with CNG fuel tank systems where the manual tank shutoff valve can get stuck closed while the knob shows open. The defect can block fuel flow, complicate safe service, create a small fuel leak, or allow tank over-pressure.
What should I do if my 2013 Freightliner M2 is on this recall?
Check your VIN to confirm your specific truck is included in recall 14V589. If it is, contact a franchised Freightliner dealer and reference recall FL-669. The remedy calls for Agility Fuel Systems dealers to replace the valve seat and stem assembly for free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the campaign remedy says the valve seat and stem assembly replacement is free of charge. Ask the Freightliner dealer to confirm the service path for the Agility fuel-system repair.
What is the safety risk?
The safety risk centers on the CNG tank shutoff valve. If the valve is stuck closed, service personnel lack a safe way to depressurize and service that valve, increasing injury risk. A detached valve seat also creates fire risk from a small valve-stem fuel leak.
