Recall 19V656 covers 330 2013-2018 Mcneilus CNG work trucks with pressure relief devices that fail to vent. Repair is free at any franchised Mcneilus dealer.
Mcneilus is recalling 330 2013-2018 Autoreach, Standard Mixer, and Rear Loader vehicles with compressed natural gas tanks because the pressure relief device can fail to vent built-up pressure. If pressure builds and the PRD does not open, the CNG tank can explode, increasing the risk of fire and injury; Mcneilus dealers will complete the free repair.

What's wrong?
The pressure relief device on these 2013-2018 Mcneilus CNG refuse and mixer vehicles is a safety valve on the compressed natural gas tank assembly. Its job is to vent gas when heat, such as from a fire, drives tank pressure too high. That controlled venting helps prevent the tank from holding pressure beyond its design limit.
The recalled Emcara thermal pressure relief devices were built with a surface finish that did not meet the supplier's specification. That rough surface increases the force needed to pull the trigger inside the device. When the trigger does not move as designed, the valve fails to open and pressure stays trapped in the CNG tank.
There is no warning sign before failure. An owner or fleet technician will not have a dashboard light, sound, smell, or driving symptom that shows the device is unable to vent during a high-heat event.
