Summary: General Motors (GM) is recalling certain model year 2007-2010 Saturn Aura and model year 2008-2010 Chevrolet Malibu and Pontiac G6 vehicles, equipped with a 4-speed automatic transmission. On these vehicles, the tabs on the transmission shift cable end may fracture and separate.
Consequence: If the tabs were to fracture and separate, the shift lever and the actual position of the transmission gear may not match. 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.
Remedy: GM will notify owners, and dealers will install a retainer over the cable end or replace the shift cable as necessary. This service will be performed free of charge. GM has not provided a notification schedule. Owners may contact General Motors at 1-800-521-7300.
