Ford Motor is recalling 39,000 SUVs after reports of 16 fires, the automaker said on Thursday.
The automaker has advised owners to park their vehicles outside and away from structures until a fix is finished.
The recall covers the 2021 model year Ford Expedition and Lincoln Navigator vehicles.
It was initiated after the report of an engine compartment fire that could occur while the car is parked or being driven, even with the ignition off.
There was one injury but no accidents related to the fires, it said, and 14 of the 16 affected vehicles were owned by rental car companies.
A remedy was still being developed and Ford was working to establish the cause.
This year, the automaker has issued 30 recalls in the United States that cover 3.5 million vehicles, higher than any other automaker.
