The automaker says the engine block heater (part numbers GJ7T-6A051-AA and GJ7T-6A051-BA) can crack and leak coolant. This can cause a short circuit when the heater is plugged in, which can then cause a fire.
Take note of this from Ford:
"The risk of underhood fire is increased when the block heater is plugged into a 110-volt electrical supply without a functional circuit breaker or Ground Fault Circuit Interrupter (GFCI) power outlet."
Ford found the heater solder joints can crack and allow coolant to enter the engine block heater. The coolant evaporates and leaves behind salt deposits that can accumulate and corrode the electrical connections. The salt can also form a "salt bridge" that is electrically conductive, causing a short circuit.
Customers should be aware of leaked coolant, a loss of heat in the cabins, overheated powertrain units and low coolant warning lights. Those are in addition to odors or smoke.
According to Ford, the majority of the incidents occurred in Canada.
Considering this is Ford's 115th safety recall of 2025, dealers are behind on getting parts and performing repairs. Interim Ford engine block heater recall letters will be mailed between October 15 and October 24, 2025. Second recall letters will be mailed when dealers have the replacement heaters, expected to be in February 2026.
