(CNN) - Ford is recalling half-a-million vehicles.
The company says they're at risk of rolling unexpectedly.
The recall affects 2013 to 2016 Fusions and 2013 to 2014 Escapes
Ford says the problem is cushions called "bushings" that help reduce vibrations.
In the affected vehicles, the ones that attach the shifter cable and transmission can come apart.
That can cause the vehicles to roll while in park.
Ford says no one has reported an injury due to the defect.
