Just recently my interior lights come on automatically while I am driving. Sometimes it is when I drive over a bump such as a railroad crossing and sometimes it is when I make a turn. The dealer says he has never heard of it before.

Sounds like you have a defective door switch, that is why the lights come on when you go over a bump. The door switch turn on the interior lights when you open the door. I would check the driver's door and the tail gate first, as they get the most use.
