The situation is especially concerning in Canada, where 46 vehicle fires have already been confirmed.
Winter is just around the corner, and auto giants Ford and Lincoln are warning owners not to use their engine block heaters. The reason: nearly 60,000 vehicles are being recalled due to a fire risk linked to potential coolant leaks from the heater components. The danger appears particularly acute in Canada, where 46 fires have already been reported.
The recall affects several popular models, including the Bronco (2021–2024), Bronco Sport, Escape (2020–2022), Maverick (2022–2024), Fusion (2019–2020), Ranger (2019–2024), and Explorer (2016–2018, 2020–2023). Lincoln vehicles on the list include the Corsair (2020–2022) and MKC (2016–2019).
According to Ford, the issue stems from solder joints in the heater assembly that may crack over time, allowing coolant to seep into the electrical connector. As the liquid evaporates, salt deposits can form, leading to corrosion or even a short circuit—especially if the heater is plugged into an improper outlet.
While engine block heaters are relatively uncommon in the U.S.—especially on gasoline-powered vehicles—the risk remains. Owners might notice signs of trouble such as coolant spots, engine overheating, reduced cabin heat, or even smoke from under the hood.
Ford launched an investigation in January following multiple incidents. Engineers discovered soldering defects in the heating elements, though the exact cause has yet to be determined.
Sales of the affected models have been suspended, and owners are urged not to use the heater until the part is replaced. Unfortunately, the fix won’t come soon — replacement components aren’t expected until February 2026.
