(Reuters) - Hyundai Motor America is recalling over 49,000 U.S. vehicles over unintentional air bag deactivation or deployment, the National Highway Traffic Safety Administration (NHTSA) said on Wednesday.

"The main floor wiring harness may chafe against the passenger-side second-row bench seat assembly and become damaged, which can cause the air bags to deploy unintentionally or prevent the air bags from deploying in a crash," the U.S. auto safety agency said.

The recall affects certain 2024 Santa Fe and Santa Fe HEV vehicles.

Separately, Hyundai Motor America is also recalling over 12,000 U.S vehicles due to unintended vehicle movement.

A return spring in the ignition lock switch, in certain 2010-2013 Genesis Coupe vehicles, may fracture, which can result in unintended vehicle movement when the vehicle is started in gear, without the parking brake applied, the agency said.
