DETROIT (AP) – Honda is recalling more than 300,000 Accord midsize cars in the U.S. because the side air bags can inflate if a door is slammed too hard. The recall covers Accords from the 2008 and 2009 model years. Honda says the side impact sensor can activate the side curtain and side seat air bags if there’s a non-vehicle impact to the lower body or a door is shut with extreme force. The ignition has to be on for the problem to happen. Nineteen people have filed injury claims with Honda because of the problem. The company says dealers will update software to adjust the threshold for air bag inflation. Customers will get recall notices in the mail starting in mid-December.
