Shanghai: Honda Motor Co. recalled about 143,000 vehicles in Japan after an air bag fitted with an inflator made by Daicel Corp. failed to deploy in a collision in which the driver was injured. The propellant used in the air bag inflators weren’t suitable and had “inappropriate velocity,” said Misato Fukushima, a spokeswoman for Honda. The recall is unrelated to Takata Corp., the supplier behind recalls of more than 28 million inflators in the US that have been found to rupture after exploding with excessive force. The Daicel inflators in the recalled vehicles are fitted into air bag modules made by Nihon Plast Co. and are not used as replacements for Takata, according to Fukushima. Daicel has stopped production of the inflator and is cooperating with Honda to conduct the recall, Daicel spokesman Masahiko Hirokawa said.
