Kia and Hyundai recalling more cars in US

Kia Motors said on Friday it was recalling more than 507,000 vehicles in the US because an electronic glitch may prevent air bags from deploying in a crash.

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 Motors after crashes in which four people were killed and another six were injured.

The two Korean car makers have now recalled nearly 1.1million US vehicles to tackle the issue. NHTSA said in March it was aware of six serious crashes in which air bags failed to deploy in frontal crashes, including four in 2011 model Hyundai Sonatas and two in 2012 and 2013 Kia Forte vehicles. The crash of the 2013 Forte occurred in Canada.

Kia’s recall issued on Friday covers 2010-13 Kia Fortes, 2011-13 Kia Optimas and 2011-12 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.

The company said it did not yet have a fix, but was working with its supplier on the issue.

Kia spokesman James Bell said that it “is attempting to have a remedy by the scheduled owner notification date of July 27”. US cars made by Korea’s Kia are to be recalled due to airbag problems
