What's wrong?
The affected 2015 Freightliner 1085D and M2 refuse trucks use compressed natural gas instead of only liquid fuel. The CNG tank stores fuel under high pressure, and the tank valve controls when that gas flows out of the tank. The valve handle is supposed to stop after one turn, so the valve parts stay seated and retained.
On these trucks, the valve design allows the handle to be tightened beyond that stop. When the handle is turned too far, torque and pressure load the snap ring inside the valve. That snap ring holds the valve stem, seal, and seat in place. If the ring fails, the valve stem can eject from the valve body instead of staying captured.
The warning sign is the handle itself. If the valve handle is being forced or tightened past one turn, stop using the handle and have the CNG system inspected before the valve is operated again.
Who's affected?
The VIN coverage is non-sequential, so the beginning and ending VINs do not include every VIN between them.

A matching 2015 Freightliner 1085D or M2 truck does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Overtightening the CNG valve knob can make the valve retaining snap ring fail and eject from the valve body, creating an injury risk for anyone in its path. An unintended CNG release also raises fire risk. Avoid overtightening the valve handle and schedule the repair soon. Repair is free at any franchised Freightliner dealer.
What should I do?
- Check your VIN to confirm your 2015 Freightliner 1085D or M2 is included in this recall.
- Contact a franchised Freightliner dealer to schedule the free CNG valve snap-ring repair.
- Ask the dealer to double the snap ring strength on the CNG tank valve, which helps keep the valve stem from ejecting and releasing CNG.
- Bring the recall notice if you have it. If not, reference recall number 19V146 when you call.
- Avoid overtightening the CNG valve knob until the repair is complete.
What happens at the repair
At the dealer, a Freightliner technician updates the CNG tank valve assembly by doubling the snap ring strength so the valve stem stays retained in the valve body. The recall repair is available now, and parts and labor are free. If you already paid for this valve or snap ring repair before the recall notice, the standard reimbursement plan is on file. Bring repair receipts and any related documentation to the service desk so the dealer can review the prior repair under that plan.
