LOS ANGELES, Calif. -

Chrysler is recalling nearly half a million cars and SUVs due to a problem with head restraints.

The recall involves approximately 442,000 vehicles in the U.S., 25,000 in Canada and 10,000 in Mexico.

Owners with affected cars will be notified, and the company will fix the problem for free.

The vehicles affected by the recall are:

    2011 to 2012 Dodge Nitros

    2011 to 2013 Chrysler Sebring 200S
