TOKYO/WASHINGTON (Reuters) – Honda Motor Co said it was ditching air bag inflators made by Japan’s Takata Corp (7312.T), after the top U.S. auto safety regulator on Tuesday fined the supplier $70 million and ordered it to stop using a potentially dangerous propellant. Regulators have linked eight deaths – all in cars made by Takata’s biggest air bag customer Honda – to the inflators, which use ammonium nitrate and can explode with too much force, spraying metal fragments inside vehicles.
