Service bulletin 511274

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

Fuel module options FS90301 and FS90453 contain an electric fuel heater. Internal electrical heating within the fuel heater may create sufficient heat inside the fuel heater to cause plastic in the fuel heater to melt and potentially catch fire. It may also cause an engine stall. A fire, if undetected and uncontained, presents an increased risk of personal injury. An unexpected engine stall may increase the risk of a crash. If this condition exists, melting of the fuel heater or fuel seepage from around the fuel heater may be visible during a service event, smoke may precede or accompany a fire, or the engine may become increasingly difficult to start.
