BEIJING/TOKYO (Reuters) – Japan’s Takata Corp (7312.T), whose potentially defective car air bags have been linked to four deaths in the United States, is unlikely to be dumped by its automaker customers given the cost and disruption of such a move – for now. Some business is leaking to rivals, but the industry doesn’t have the spare capacity to make a significant dent in Takata’s contracts. “Takata’s not going away,” said Scott Upham, a former executive at Takata and at third-ranked TRW Automotive Holdings Corp (TRW.N) and now president of Valient Market Research.
