"Our Tucson sales are so good that dealers' top complaint is 'Why can't you get us more?'" said Mike O'Brien from the Korean automaker's U.S. unit, speaking at the Detroit auto show.

O'Brien said the company expects imports of Tucson SUVs in 2016 to double from the more than 40,000 vehicles it sold into the U.S. market in 2015.
