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.

Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
