The recall involves Chevrolet Malibus from model years 2008-2010, Pontiac G6 vehicles from the same years and Saturn Auras from model years 2007-2010, the National Highway Traffic Safety Administration said Monday.
The models recalled have four-speed automatic transmissions.
The faulty component is the gear position indicator, which relies on tabs at the end of a transmission shift cable to properly align the indicator with the shifter. When the tabs fracture, "the driver would be able to move the shifter to 'PARK' and remove the ignition key, but the transmission gear may not be in 'PARK.' The vehicle may not be able to be restarted and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning," the commission said in a statement.
GM will replace the shift cable or install a retainer over the cable end free of charge, the NHTSA said.
