General Motors is recalling 15,575 Cadillac, Buick and Chevrolet cars to correct potential safety flaws.

The recalls, posted earlier this week by the National Highway Traffic Safety Administration, involve 2,949 2012 model Buick Verano, Chevrolet Cruze and Chevrolet Sonic compacts with driver side air bags that might not deploy in a crash.

Also involved are 12,626 2013 model Cadillac XTS sedans with rear-seat head restraints that might not lock in position. The problems could increase the risk of injury to occupants, NHTSA said.

GM said it will replace the steering wheel airbag coil on the compact cars and replace the head restraints on the Cadillacs. GM dealers will provide the repairs free of charge.
