Hyundai is voluntarily recalling 139,500 of its Sonata sedans in the U.S. because steering columns in some of the vehicles may not have been properly assembled.
The manufacturing defect means steering column connections could become unattached, causing drivers to lose control of the vehicles, according to the National Highway Transportation Safety Board's Web site.
The affected automobiles were manufactured between Dec. 11, 2009 through Sept. 10, 2010.
Hyundai dealers will inspect the steering columns of those automobiles and update the power steering software free of charge. The recall is expected to begin in October.
In February, Hyundai also recalled 47,000 Sonata sedans following customer complaints that some front-door latches didn't close properly.
