Andrea,
In reference to your post: http://www.priusonline.com/22-toyota-prius-technical-q/32890-exclamation-warning-light-occasional-goes-stays-day.html
I haven't personally observed this symptom in my Prius, and I doubt anyone will be able to give you much assistance without knowing what engine codes are stored when the exclamation symbol is displayed. Next time you see it, take you car in to the nearest auto parts store and ask them to read out your codes. (AutoZone will do this for free, for example.) There may be several codes, and they will be in a format like "P3191". Post that information and see if you get more help.
