Honda plans to replace the replace driver’s air bag inflators on 2.6 million more vehicles as it expands repairs to the entire U.S. The Japanese automaker is the only company to comply with demand from the U.S. National Highway Traffic Safety Administration to do repairs nationwide. Honda says it’s doing so to address customer concerns. Air bags made by Japanese supplier Takata Corp. can inflate with too much force, blowing apart a metal canister and spewing shrapnel. At least five people have died due to the problem. Honda and other automakers have limited recalls to high-humidity states mainly along the Gulf Coast.
