Honda is recalling more than a million Accords because a battery sensor can short out and that could start a fire.
The recall covers 2013-2016 model years.
Honda says it has four reports of engine compartment fires but no injuries.
All reports were in states where salt is used on roads in the winter.
Salt can get in and cause an electrical short in the battery, leading to a fire.
Dealers will inspect the sensors and replace faulty ones.
Those without problems will be replaced when more parts are available.
