ORLANDO, Fla. -

Korean automakers Hyundai and Kia are recalling almost 1.9 million vehicles to fix problems with air bags and brake light switches.

The brake light recall covers the Hyundai Accent, Elantra, Genesis Coupe, Santa Fe, Sonata, Tucson and Veracruz.  The same problem has prompted the recall of Kia's Optima, Rondo, Sedona, Sorento, Soul and Sportage, as well. The Hyundai-Kia vehicles affected are from the 2007 through 2011 model years.

U.S. safety regulators say a faulty switch can stop the brake lights from illuminating when drivers press the pedal. Also, the cruise control may not turn off when a driver steps on the brake, push-to-start buttons may not work, and a feature that stops the driver from shifting out of park without a foot on the brake may fail.  These issues, according to the National Highway Traffic Administration, increase the risk of a crash.

The automakers will notify owners and replace the switches for free starting in June.

Separately, Hyundai is recalling the 2011 through 2013 Elantra. A bracket can come loose when the side air bag inflates, causing possible injury to passengers.
