(Reuters) - The ongoing upheaval in General Motors Co.'s (GM) executive ranks continued with the sudden resignation of Chris Perry as vice president of Chevrolet marketing. Perry, 53, spent just over three years in the job, after being wooed to GM in mid-2010 by Joel Ewanick, his former boss and colleague at Hyundai Motor America.
Earlier in 2010, Perry had replaced Ewanick as vice president of marketing at the Korean automaker's U.S. operation. Ewanick was fired by GM as its global marketing chief in August 2012 for not properly disclosing the full cost of a $559-million sponsorship deal with English soccer club Manchester United.
