What's wrong?
The affected 2016-2018 Mcneilus and S-Series vehicles use MPVE-250 One-Turn Valves on their CNG fuel tanks. A CNG tank stores compressed natural gas under pressure, and this valve is the hand-operated shutoff point that controls fuel flow from the tank. The knob is designed to open or close the valve with one turn.
The problem starts when the valve knob is turned past that intended range. If it is turned more than one turn, the snap ring that holds the valve stem in place loses its hold, and the valve stem can eject from the valve body. Mcneilus also identified handle or valve-body separation under pressure. That means the shutoff valve itself no longer stays assembled while the tank is pressurized.
There is no warning sign before failure. An owner or operator should not expect a sound, light, or change in how the vehicle runs before the valve separates.

The year, make, and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A valve stem can be forcibly ejected, which puts nearby people at risk of injury. Unintended CNG release also raises fire risk. There is no warning sign before this happens. Schedule the recall repair soon and keep people away from the valve area during service or inspection. Repair is free at any franchised Mcneilus dealer.
What should I do?
- Check your VIN to confirm your 2016-2018 Mcneilus Xe Rear Loader, Standard Mixer, Bridgemaster V Mixer, Meridian Front Loader 78, Atlantic Front Loader, or S-Series is included in this recall.
- Contact a franchised Mcneilus dealer to schedule the free valve replacement that fixes the CNG tank valve stem ejection and gas-release risk.
- Bring the recall notice if Mcneilus mailed one. If not, reference recall number 18V858 when you call.
- Avoid turning the CNG tank valve knob more than one turn until the valve replacement is complete.
- Call Mcneilus customer service at 1-888-686-7278 with questions about scheduling or repair status.
