Kia recalls over 500,000 vehicles in U.S.
The recall follows an announcement in March by the National Highway Traffic Safety Administration (NHTSA) that it was investigating why some air bags had failed to deploy in Kia vehicles and its affiliate Hyundai Motor after crashes in which four people were killed and another six injured involving the two automakers' vehicles.
Kia's recall issued on Friday covers 2010-2013 Kia Fortes, 2011-2013 Kia Optimas and 2011-2012 Kia Optima Hybrid and Sedona vehicles.
The company said the air bag control unit may short circuit because they may be susceptible to electrical overstress, preventing the frontal air bags and seat belt pretensioners, which pull the driver and front seat passenger firmly back into their seats, from deploying. ■
