GMC vehicles included in the recall list for transmission problems as of 2015 are model years 2008 through 2010 of the Chevrolet Malibu and Pontiac G6, along with the Saturn Aura in model years 2007 through 2010. These vehicles potentially have problems with the automatic transmission system that makes them roll away when parked. This recall affects over 425,000 vehicles in the models listed above, but applies only to those cars with a four-speed automatic transmission system.
Regardless of model, the problem in GM's transmission recall is the same. Tabs on the ends of the transmission shift cables in these cars may break. When drivers put their cars in "Park," cars with frayed cables do not register that information and can move suddenly when parked.
In response to concerns over faulty transmission systems, GM encourages owners of these models to contact authorized service centers for repairs, even if their cars have not yet exhibited symptoms. Professionals at authorized locations then either replace the faulty parts or repair them, at no cost to the customers.
Owners with affected models can contact either GM or the National Highway Traffic Safety Administration, notes Autotrader. People shopping for vehicles in those models should make sure the at-risk parts have been repaired or replaced prior to making a purchase.
