Defect
On certain trucks, the electric fuel heater could overheat. As a result, the fuel heater housing could melt, and fuel could leak into the connector. If this happens, the connection terminals could overheat and melt. Note: This problem could cause the engine not to start or to have trouble starting.
Safety Risk
A fuel leak and/or a connector that overheats and melts can increase the risk of a fire.
Remedy
Isuzu will notify owners by mail and advise you to take your truck to a dealership to replace the electric fuel heater. The dealer will also inspect and, if necessary, repair any damaged connector.
