Service bulletin TSB150196-031620
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This Technical Service Bulletin desribes the troubleshooting steps to diagnose natural gas leaks into the engine cooling system. Many natural gas fuel systems use engine coolant to warm the natural gas high pressure regulator and/or heat exchanger. A leaking original equipment manufacturer (OEM) high pressurer fuel system component can cause natural gas to leak into the engine cooling system. This is an update to a previously submitted communication.
