In the presence of an ignition source, a complete discharge of a full CNG tank in an enclosed environment or adjacent to certain structures can increase the risk of a fire.
Daimler Trucks North America, LLC (DTNA) is recalling certain 2018-2019 Freightliner Business Class M2 and 114SD compressed natural gas (CNG) vehicles equipped with Agility Pressure Relief Devices (PRD). A damaged o-ring may cause the PRD to vent at a lower pressure, potentially resulting in a complete discharge of a full CNG tank.
DTNA will notify owners, and Agility authorized service facilities will install a new pressure regulator kit, free of charge. The recall is expected to begin December 3, 2018. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-798.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
