Hyundai Motor Co. is recalling 139,500 Sonata sedans in the U.S. because of a manufacturing defect that could cause drivers to lose steering control, according to AP. The recall affects 2011 models built between Dec. 11, 2009, and Sept. 10, the National Highway Traffic Safety Administration said on its website Sunday. Some of the cars have steering column shafts with connections that may not have been tightened enough or were improperly assembled. As a result, the steering wheel could become separated from the column or a driver could lose the ability to properly steer the car. Owners of affected vehicles can go to their dealers for inspection. Dealers also will update power steering software. The South Korean automaker did not immediately return messages left seeking comment Sunday. In February, Hyundai announced a recall of about 47,000 Sonata midsize sedans to replace front door latches following a handful of customer complaints. The car maker said it had discovered a mechanical problem with the latches which, in rare instances, would not close properly. So far this year, U.S. sales are up 17 percent for Hyundai Motor America, though August sales fell 11 percent from a year-earlier record sparked by federal Cash for Clunkers rebates. The new Sonata has been selling well and nearly doubled its sales numbers to 21,399 in August.
