I have a 2017 F-350 SuperDuty with the Engine Block Heater option, two recalls have been issued related to a condition that can cause overheating of the power cord with the possibility of a fire. Recall 18V-894 and 19V-278 have both been applied and verified by Ford Customer Service. During the recent cold weather in the Houston, Texas area, the engine block heater was used to keep the engine warm to assist with starting. When I disconnected the power cord the was hot enough to have melted the plug to the point where the blades in the plug were loose and I had to use gloves to separate the engine heater cord from the extension cord. This should have been fixed under one or both of the previous recalls. It represents an electrical hazard that could lead to fire and loss of property. I asked Ford to remedy the situation under case XXX and they have declined to resolve the hazard. Please review this case and have Ford issue a third recall to remedy this safety issue. I have provided pictures to assist in your determination. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
