Ford Motor Co. said Thursday it is recalling about 39,000 large SUVs and advising owners to park affected models outside and away from structures, after receiving multiple reports of under-the-hood fires while the vehicles were parked and off.

Ford, filing a recall notice with the National Highway Traffic Safety Administration this week, said the recall campaign covers 2021 Ford Expedition and Lincoln Navigator SUVs built between late 2020 and early 2021.

The Dearborn, Mich., auto maker said it had yet to establish a cause, but advised drivers to take the precautions outlined in the recall, while the fire incidents are being investigated.

Ford said it is aware of 16 incidents in which a fire originated under-the-hood for the gasoline-powered SUVs. Twelve of those happened while the vehicle was parked and the ignition off. One occurred while the vehicle was parked but on, and three more fires ignited while the vehicle was in motion, the company said.

Ford said it has learned of one injury related to the fire incidents.

The safety recall comes as the auto industry is confronting a wave of fire reports in parked vehicles, many of them in electric-vehicle models where the blaze is suspected to have originated with the battery.

This latest recall stands out in that the affected models are more traditional gas-engine vehicles.

Earlier this year, Hyundai Motor Group recalled more than 468,000 vehicles, mostly gas-engine crossovers and SUVs, for a similar fire risk. It said it discovered a problematic anti-lock brake system that could malfunction internally. The problem could lead to an electrical short and potentially cause an engine compartment fire, including while the vehicles are parked, the company said in its recall reports.

As part of the recall, Hyundai has told affected owners to park their cars outside and away from structures, while it tries to identify a remedy. In April, Hyundai said it had a fix and advised owners to bring their vehicles to a dealership to have the defective part replaced.

Ford told the NHTSA that its investigation into the apparent problem began in March, after receiving reports of under-the-hood fires in multiple 2021 Ford Expeditions. It later uncovered other incidents linked to its Lincoln Navigator. Some customers reported a burning smell and smoke coming from the engine compartment on the passenger side, Ford said.

The vehicles were manufactured between Dec. 19, 2020, and April 20, 2021. Ford said there have been no reported incidents in vehicles built outside of that time frame.

While a remedy has yet to be completed, Ford said owners of the recalled vehicles can keep driving them in the meantime and that it is unaware of any accidents related to the fire risk.
