shift lever on f-250 shifting with keys out of ignition, brake not compressed

What is your question?

question: My wifes grandpa has a 2002 F-250. My two year old son was sitting in the drivers seat pretend driving in the driveway, and he pulled down on the gear shift and the truck rolled about 5 feet impacting my wifes jeep. He did not have the keys, nor is he able to press the brake pedal. Is this a common problem or is there a recall that could be affecting this year and model of truck?
