ENGINE AND ENGINE COOLING — Tailpipe may Activate CNG Pressure Relief Device · December 7, 2015

The problem

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2013-2015 Freightliner Cascadia vehicles manufactured March 27, 2015, to November 4, 2014, and powered by compressed natural gas (CNG). The affected vehicles have a tailpipe that allows hot exhaust to exit near the CNG tank pressure relief device (PRD).

Risk

Hot exhaust in close proximity to the PRD may cause the PDR to activate and CNG to be unexpectedly released from the tank. Discharge of CNG in the presence of an ignition source can increase the risk of a fire.
