Swedish automaker Volvo is recalling 9,746 cars in the U.S. to repair driver's side airbags that may not deploy during a crash, the National Highway Traffic Safety Administration reported Wednesday.

Faulty wiring may prevent the driver's side airbag from deploying as intended or at all, increasing the risk of injuries during a crash, NHTSA said in a posting on its website. The models involved are the 2010 and 2011 S80 and XC70; the 2010 V70; and the 2011 XC60.

To remedy the defect, dealers will install a metal shim in the airbag's clockspring wiring connector, NHTSA said. The repairs will be done free of charge.

Owners of affected vehicles will begin receiving notices on Oct. 29 with instructions on where to bring recalled vehicles for repair.

Volvo was until recently a part of Ford Motor (F). The Dearborn, Mich., company completed the sale of the European luxury brand to China's Geely Holding Group in August.
