What's wrong?
The engine block heater on 2023-2025 Bronco Sport, Escape, Maverick, Corsair, and Nautilus vehicles is an electric heater mounted in the engine block. Its job is to warm coolant around the 1.5L or 2.0L MPC engine when the vehicle is parked and plugged in, which helps cold-start performance and cabin heat.
In affected vehicles, the heater element design, its position in the engine block, and the installation angle leave the element vulnerable to trapped coolant vapor or air. When the block heater is plugged in, that trapped pocket lets the element overheat instead of staying surrounded by coolant. Ford's recall replaces the JL3T-6A051-AB block heater with a different design.
Owners have warning signs to watch for before the heater fails. Coolant leakage under the vehicle, a check engine light, weaker cabin heat, or heat damage at the block heater electrical connector all point to this condition.

What should I do?

- Watch for Ford's second owner notice before scheduling the final block-heater repair.
- Avoid plugging in the engine block heater while the vehicle is parked until the free remedy is available.

- Reference recall number 25V343 and Ford recall 25S52 when you call Ford customer service or the dealer.
What happens at the repair
The final dealer repair is still listed as under development, so do not treat it as ready to schedule until Ford opens it. Once available, a Ford technician will replace the engine block heater element and inspect the electrical cord, replacing the cord if it needs replacement. Ford also lists an option to install a threaded blanking plug and remove the block heater cord. Parts and labor are free under the recall. Ford's standard reimbursement plan applies to documented related repairs paid before the recall notice. Bring repair paperwork to the service desk or contact Ford customer service about a claim.
