I've never had the problem, so consider this hearsay....  I've heard that the 
typical explanation is that the "multi-function" sensor has gone bad.  On the 
5000 it is located near the valve cover about one quarter of the way back from 
the engine.  If I were the owner of this car, I'd want to know if said sensor 
also controlled the radiator fan.  If it does, you might be a little concerned 
about taking a trip, paricularly if you will be doing stop and go driving in 
warm weather....
