The South Korean automaker saw its U.S. market share declining since it had reached a record-high 5.1 percent in 2011, stymied by a lack of manufacturing capacity and newer models, and as U.S. and Japanese rivals made a comeback.

David Zuchowski, Hyundai's former U.S. sales chief who took over from John Krafcik this month, also said it expects U.S. industry sales to reach 15.9 million vehicles this year, from last year's 15.6 million vehicles.

He said the company would be able to "squeeze" more output from its manufacturing facilities in the United States and receive more cars from South Korea, as Hyundai plans to expand capacity in China and other countries.
