In a newer car you could have something like this if a module was incorrectly programmed with the wrong options, or if you replace / reprogram a module, you have to set-up / learn other modules to it. Maybe it's a cluster from a different car, or maybe the original was sent in for repairs, and the rebuilder did something wrong.... But that doesn't really help, since if it were anything along those lines there wouldn't be much todo without dealer info / tools
As for what to do about it, disconnect the battery(s) for 10min, I don't know how many batteries you may have, and see if it has any affect.
