For a second time, Kia is recalling more than 440,000 vehicles in the U.S. to fix a problem that can cause engine fires.

The recall covers certain Optima sedans from 2013 through 2015 and Sorento SUVs from 2014 and 2015.

Kia is telling owners to park them outdoors and away from structures because fires could happen when the engines aren't running.

The same vehicles were recalled last year because brake fluid can leak into a control computer, causing an electrical short.
