Nearly 200,000 Santa Fe vehicles made between 2007 and 2009 have been recalled. The company has received complaints from some adults under 130 pounds because the air bag did not deploy. The air bags were originally programmed not to go off to protect children.
Hyundai will reprogram the front passenger air bag sensors so they will accurately detect when a small adult is seated.
The company also recalled 22,500 Sonata sedans from the 2012 and 2013 model years because their side air bags could go off without warning.
Hyundai says it has received 16 complaints about the Sonata's air bags, but no injuries have been reported.
Owners may contact Hyundai at 1-800-633-5151.
